Question 1

At the farm, there are chickens in three coops. The first coop has 55 chickens. The second coop has the same number of chickens as the first coop. The third coop has 22 more chickens than the second coop. How many chickens are at the farm?

  1. 1212 chickens at the farm
  2. 1919 chickens at the farm
  3. 1717 chickens at the farm (correct answer)
  4. 2222 chickens at the farm
Explanation: When you see a word problem with multiple groups and different amounts, you need to carefully figure out how many are in each group, then add them all together. Let's work through each coop step by step. The first coop has 55 chickens - that's given directly. The second coop has "the same number" as the first coop, so it also has 55 chickens. The third coop has 22 more chickens than the second coop, so that's 5+2=75 + 2 = 7 chickens. Now add up all three coops: 5+5+7=175 + 5 + 7 = 17 chickens total at the farm. Looking at the wrong answers: Choice A gives 1212 chickens, which you'd get if you forgot to add the third coop entirely (5+5+2=125 + 5 + 2 = 12) - this misses that the third coop has 22 more than the second coop, not just 22 chickens. Choice B gives 1919 chickens, which might come from adding incorrectly or misreading one of the amounts. Choice D gives 2222 chickens, which could happen if you mistakenly thought the third coop had 22 more than both other coops combined. The key strategy for multi-step word problems is to work through each piece of information in order, writing down what you know after each step. Don't try to do all the math in your head - keep track of each group's amount before adding them together.

Question 2

There are 5 apples in a basket, 5 apples on the table, and 4 apples on the counter. How many apples are there in all?

  1. 14 (correct answer)
  2. 10
  3. 13
  4. 15
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to identify doubles (like 5+55+5), add them first, then the third; grouping helps, and addition is commutative and associative. The story presents three quantities: 5 apples in a basket, 5 on the table, and 4 on the counter. Choice A is correct because adding all three gives 5+5+4=145 + 5 + 4 = 14; we can add the doubles 5+5=105+5=10, then 10+4=1410+4=14. Choice B is a common error where students only add two numbers, like 5+5=105+5=10, forgetting the third; this is due to challenges in tracking multiple addends. To help students: Use fruit manipulatives in groups; teach doubles explicitly; demonstrate groupings like (5+5)+4(5+5)+4; use pictures of locations; practice with similar problems and discuss errors.

Question 3

Read the problem. Maya got 6 stickers on Monday, 4 stickers on Tuesday, and 6 stickers on Wednesday. How many stickers did Maya get altogether?

  1. 16 (correct answer)
  2. 12
  3. 10
  4. 15
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for doubles (like 6+6), add those first, then the third number; another is to make 10 with pairs (like 6+4) and use commutative and associative properties. The story presents three quantities: 6 stickers on Monday, 4 stickers on Tuesday, and 6 stickers on Wednesday. Choice A is correct because adding all three numbers gives 6 + 4 + 6 = 16; for example, add 6+4=10 first, then 10+6=16, or add the doubles 6+6=12 then 12+4=16. Choice B is a common error where students add only two numbers, like 6+6=12 and forget the 4; this happens because keeping track of three numbers is challenging and students may focus on two. To help students: Use physical objects in three groups that students can count and combine; teach doubles facts explicitly (6+6=12); practice making-10 strategy; model different groupings using parentheses like (6+6)+4; use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; connect to real contexts with three groups.

Question 4

In a game, Chen scored 8 points in round 1, 2 points in round 2, and 1 point in round 3. How many points did Chen score altogether?

  1. 10
  2. 11 (correct answer)
  3. 12
  4. 9
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 6+4 or 7+3), add those first, then add the third number; another strategy is to look for doubles (like 4+4) or numbers that are easy to add together, combine those first, then add the remaining number; students can add in any order because of the commutative and associative properties. The story presents three quantities: 8 points in round 1, 2 points in round 2, and 1 point in round 3. Choice B is correct because adding all three numbers gives 8 + 2 + 1 = 11; we can add 8+2=10 first, then 10+1=11. Choice A is a common error where students only add two of the three numbers, such as 8+2=10, and forget to add the third; this happens because keeping track of three numbers is challenging. To help students: Use physical objects in three groups that students can count and combine; teach making-10 strategy explicitly with pairs that sum to 10; practice doubles facts (3+3, 4+4, 5+5); model different groupings using parentheses: (8+2)+1 or 8+(2+1); use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; practice with various number combinations; connect to real contexts with three groups.

Question 5

Lisa is reading a book with three chapters. Chapter 1 has 99 pages. Chapter 2 has 33 fewer pages than Chapter 1. Chapter 3 has 44 pages. How many pages does Lisa's book have?

  1. 1616 pages in the book
  2. 1919 pages in the book (correct answer)
  3. 2222 pages in the book
  4. 2525 pages in the book
Explanation: Chapter 1: 9 pages. Chapter 2: 3 fewer than Chapter 1 means 9 - 3 = 6 pages. Chapter 3: 4 pages. Total: 9 + 6 + 4 = 19 pages. Choice A (16) occurs if student adds 9 + 3 + 4, misunderstanding 'fewer'. Choice C (22) occurs if student adds 9 + 9 + 4, ignoring the 'fewer' completely. Choice D (25) occurs if student adds 9 + 12 + 4, thinking '3 fewer' means '3 more'.

Question 6

Maya has 33 red balloons. Her friend gives her 44 blue balloons. Then her mom gives her some yellow balloons. Now Maya has 1111 balloons in total. How many yellow balloons did her mom give her?

  1. 44 yellow balloons (correct answer)
  2. 55 yellow balloons
  3. 77 yellow balloons
  4. 88 yellow balloons
Explanation: Maya starts with 3 red balloons, gets 4 blue balloons, so she has 3 + 4 = 7 balloons. She ends with 11 total, so the yellow balloons = 11 - 7 = 4. We can check: 3 + 4 + 4 = 11. Choice B (5) gives 3 + 4 + 5 = 12, which is too many. Choice C (7) gives 3 + 4 + 7 = 14, which is too many. Choice D (8) gives 3 + 4 + 8 = 15, which is too many.

Question 7

Emma has 3 toy cars, 3 toy trucks, and 4 toy blocks. How many toys does Emma have in all?

  1. 6
  2. 9
  3. 10 (correct answer)
  4. 11
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 6+4 or 7+3), add those first, then add the third number; another strategy is to look for doubles (like 4+4) or numbers that are easy to add together, combine those first, then add the remaining number; students can add in any order because of the commutative and associative properties. The story presents three quantities: 3 toy cars, 3 toy trucks, and 4 toy blocks. Choice C is correct because adding all three numbers gives 3 + 3 + 4 = 10; we can add the doubles 3+3=6 first, then 6+4=10. Choice A is a common error where students only add two of the three numbers, such as 3+3=6, and forget to add the third; this happens because keeping track of three numbers is challenging. To help students: Use physical objects in three groups that students can count and combine; teach making-10 strategy explicitly with pairs that sum to 10; practice doubles facts (3+3, 4+4, 5+5); model different groupings using parentheses: (3+3)+4 or 3+(3+4); use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; practice with various number combinations; connect to real contexts with three groups.

Question 8

Jamal has 4 pencils. Sofia has 4 pencils. Chen has 5 pencils. How many pencils do they have altogether?

  1. 8
  2. 12
  3. 13 (correct answer)
  4. 5
Explanation: This question tests 1st grade ability to add three whole numbers with sum≤20sum \leq 20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 6+46+4 or 7+37+3), add those first, then add the third number; another strategy is to look for doubles (like 4+44+4) or numbers that are easy to add together, combine those first, then add the remaining number; students can add in any order because of the commutative and associative properties. The story presents three quantities: 4 pencils from Jamal, 4 pencils from Sofia, and 5 pencils from Chen. Choice C is correct because adding all three numbers gives 4+4+5=134 + 4 + 5 = 13; we can add the doubles 4+4=84+4=8 first, then 8+5=138+5=13. Choice A is a common error where students only add two of the three numbers, such as 4+4=84+4=8, and forget to add the third; this happens because keeping track of three numbers is challenging. To help students: Use physical objects in three groups that students can count and combine; teach making-10 strategy explicitly with pairs that sum to 10; practice doubles facts (3+33+3, 4+44+4, 5+55+5); model different groupings using parentheses: (4+4)+5(4+4)+5 or 4+(4+5)4+(4+5); use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; practice with various number combinations; connect to real contexts with three groups.

Question 9

Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 6+4 or 7+3), add those first, then add the third number; another strategy is to look for doubles (like 4+4) or numbers that are easy to add together, combine those first, then add the remaining number; students can add in any order because of the commutative and associative properties. The story presents three quantities: 6 red marbles, 4 blue marbles, and 3 green marbles. Choice C is correct because adding all three numbers gives 6 + 4 + 3 = 13; we can add 6+4=10 first, then 10+3=13. Choice A is a common error where students only add two of the three numbers, such as 6+4=10, and forget to add the third; this happens because keeping track of three numbers is challenging. To help students: Use physical objects in three groups that students can count and combine; teach making-10 strategy explicitly with pairs that sum to 10; practice doubles facts (3+3, 4+4, 5+5); model different groupings using parentheses: (6+4)+3 or 6+(4+3); use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; practice with various number combinations; connect to real contexts with three groups.

Question 10

There are 2 books on the desk, 3 books on the shelf, and 6 books on the table. How many books are there altogether?

  1. 11 (correct answer)
  2. 9
  3. 10
  4. 12
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to pair easy adds (like 2+3=5), then add the third; order is flexible. The story presents three quantities: 2 books on the desk, 3 on the shelf, and 6 on the table. Choice A is correct because adding all three gives 2 + 3 + 6 = 11; we can add 2+3=5, then 5+6=11. Choice B is a common error from misadding, like 2+3+4=9 instead of 6; fact errors cause this. To help students: Use book piles; teach small pairs; model groupings; location visuals; practice verbalizing.

Question 11

At breakfast, Maya ate 3 grapes. At lunch, she ate 7 grapes. At dinner, she ate 4 grapes. How many grapes did Maya eat in all?

  1. 10
  2. 13
  3. 14 (correct answer)
  4. 15
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to pair numbers to make 10 (like 3+7), then add the third; order doesn't matter. The story presents three quantities: 3 grapes at breakfast, 7 at lunch, and 4 at dinner. Choice C is correct because adding all three gives 3 + 7 + 4 = 14; we can add 3+7=10, then 10+4=14. Choice B is a common error from adding only two, like 3+7=10, forgetting the third, or miscalculating 10+3=13; tracking issues cause this. To help students: Use meal-time visuals; teach making-10; model (3+7)+4; connect to daily eating; practice with counters and verbalize.

Question 14

Emma collected stickers on three different days. On Monday she found 66 stickers. On Tuesday she found 22 fewer stickers than Monday. On Wednesday she found 33 stickers. How many stickers did Emma collect in total?

  1. 1111 stickers in total
  2. 1313 stickers in total (correct answer)
  3. 1515 stickers in total
  4. 1717 stickers in total
Explanation: Monday: 6 stickers. Tuesday: 2 fewer than Monday means 6 - 2 = 4 stickers. Wednesday: 3 stickers. Total: 6 + 4 + 3 = 13 stickers. Choice A (11) occurs if student adds 6 + 2 + 3, misunderstanding 'fewer'. Choice C (15) occurs if student adds 6 + 6 + 3, ignoring the 'fewer' completely. Choice D (17) occurs if student adds 6 + 8 + 3, thinking '2 fewer' means '2 more'.

Question 15

At a birthday party, there are 33 tables. The first table has 66 children. The second table has 11 more child than the first table. The third table has 22 children. How many children are at the party?

  1. 99 children at the party
  2. 1414 children at the party
  3. 1515 children at the party (correct answer)
  4. 1616 children at the party
Explanation: First table: 6 children. Second table: 1 more than the first table means 6 + 1 = 7 children. Third table: 2 children. Total: 6 + 7 + 2 = 15 children. Choice A (9) occurs if student adds 6 + 1 + 2, misunderstanding the second table. Choice B (14) occurs if student adds 6 + 6 + 2, ignoring the 'more'. Choice D (16) occurs if student adds 6 + 8 + 2, thinking '1 more' means '2 more'.

Question 16

Sofia has 6 red stickers, 4 blue stickers, and 3 green stickers. How many stickers does Sofia have in all?

  1. 10
  2. 12
  3. 13 (correct answer)
  4. 9
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 6+46+4 or 7+37+3), add those first, then add the third number; another is to look for doubles or easy pairs, and students can add in any order due to commutative and associative properties. The story presents three quantities: 6 red stickers, 4 blue stickers, and 3 green stickers. Choice C is correct because adding all three numbers gives 6+4+3=136 + 4 + 3 = 13; we can add 6+4=106+4=10 first, then 10+3=1310+3=13. Choice A is a common error where students only add two of the three numbers, like 6+4=106+4=10, forgetting the third; this happens because keeping track of three numbers is challenging for young learners. To help students: Use physical objects in three groups that they can count and combine; teach the making-10 strategy explicitly with pairs that sum to 10; practice with visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy.

Question 17

Keisha has 7 marbles. Carlos has 3 marbles. Yuki has 6 marbles. How many marbles do they have altogether?

  1. 10
  2. 15
  3. 16 (correct answer)
  4. 14
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to find pairs that make 10 (like 7+3), add first, then the third; doubles or easy adds work too, with flexible ordering. The story presents three quantities: 7 marbles from Keisha, 3 from Carlos, and 6 from Yuki. Choice C is correct because adding all three gives 7 + 3 + 6 = 16; we can add 7+3=10 first, then 10+6=16. Choice D is a common error from misadding after pairing, like 10+4=14 instead of 6; this stems from non-automatic facts or distraction. To help students: Use marble bags for groups; teach making-10 explicitly; model with parentheses (7+3)+6; connect to sharing games; have students practice and explain.

Question 18

Read the problem. Marcus scored 4 points in round 1, 6 points in round 2, and 5 points in round 3. How many points did he score in all?

  1. 10
  2. 14
  3. 15 (correct answer)
  4. 16
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 4+6), add those first, then the third number; another is to add in any order using commutative and associative properties. The story presents three quantities: 4 points in round 1, 6 points in round 2, and 5 points in round 3. Choice C is correct because adding all three numbers gives 4 + 6 + 5 = 15; for example, add 4+6=10 first, then 10+5=15. Choice A is a common error where students only add two numbers, like 4+6=10 and forget the 5; this happens because keeping track of three numbers is challenging and applying strategies requires practice. To help students: Use physical objects in three groups that students can count and combine; teach making-10 strategy explicitly with pairs that sum to 10; practice doubles facts; model different groupings using parentheses like (4+6)+5; use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; connect to real contexts with three groups.

Question 19

Yuki has 7 cookies after lunch, 3 cookies after snack, and 2 cookies after dinner. How many cookies does Yuki have in all?

  1. 10
  2. 12 (correct answer)
  3. 13
  4. 7
Explanation: This question tests 1st grade ability to add three whole numbers with sum≤20sum \leq 20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 6+46+4 or 7+37+3), add those first, then add the third number; another strategy is to look for doubles (like 4+44+4) or numbers that are easy to add together, combine those first, then add the remaining number; students can add in any order because of the commutative and associative properties. The story presents three quantities: 7 cookies after lunch, 3 cookies after snack, and 2 cookies after dinner. Choice B is correct because adding all three numbers gives 7+3+2=127 + 3 + 2 = 12; we can add 7+3=107+3=10 first, then 10+2=1210+2=12. Choice A is a common error where students only add two of the three numbers, such as 7+3=107+3=10, and forget to add the third; this happens because keeping track of three numbers is challenging. To help students: Use physical objects in three groups that students can count and combine; teach making-10 strategy explicitly with pairs that sum to 10; practice doubles facts (3+33+3, 4+44+4, 5+55+5); model different groupings using parentheses: (7+3)+27+3)+2 or 7+(3+2)7+(3+2); use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; practice with various number combinations; connect to real contexts with three groups.

Question 20

Read the problem. Carlos has 1 cookie at breakfast, 8 cookies at lunch, and 6 cookies at dinner. How many cookies did Carlos have in all?

  1. 14
  2. 15 (correct answer)
  3. 9
  4. 16
Explanation: This question tests 1st grade ability to add three whole numbers with sum ≤20≤20 (CCSS.1.OA.2). When adding three numbers, students can use helpful strategies to make it easier. One strategy is to look for two numbers that make 10 (like 6+46+4 or 7+37+3), add those first, then add the third number; another strategy is to look for doubles (like 4+44+4) or numbers that are easy to add together, combine those first, then add the remaining number; students can add in any order because of the commutative and associative properties. The story presents three quantities: 1 cookie at breakfast, 8 cookies at lunch, and 6 cookies at dinner. Choice B is correct because adding all three numbers gives 1+8+6=151 + 8 + 6 = 15; we can add 1+8=91+8=9 first, then 9+6=159+6=15, or group 8+6=148+6=14 and 14+1=1514+1=15. Choice A is a common error where students only add two of the three numbers, such as 8+6=148+6=14 and forgetting the 1, or make a calculation error like 1+8=91+8=9 and 9+5=149+5=14 by miscounting the 6; this happens because students may focus on two numbers and lose track of the third. To help students: Use physical objects in three groups that students can count and combine; teach making-10 strategy explicitly with pairs that sum to 10; practice doubles facts (3+33+3, 4+44+4, 5+55+5); model different groupings using parentheses: ((1+8)+6(1+8)+6 or 1+(8+6)1+(8+6)); use visual representations showing three groups; emphasize that order doesn't matter; have students explain their strategy; practice with various number combinations; connect to real contexts with three groups.
