All questions

Question 1

Use the bar graph of Favorite Fruits to answer the question. How many more students chose apples than chose grapes?

  1. 22
  2. 33 (correct answer)
  3. 55
  4. 1111
Explanation: When you see a bar graph question asking "how many more," think subtraction. You need to find the value for each bar mentioned, then subtract the smaller number from the larger one. The word "more" is your clue to compare two amounts. For this question, you'd look at the bar labeled "Apples" and read its height on the scale, then do the same for "Grapes." Based on the graph, apples had 88 students and grapes had 55 students. To find how many more students chose apples, subtract: 8−5=38 - 5 = 3. That matches choice B. Choice A (22) is a common slip-up if you misread one of the bars by a single unit — always double-check where the top of the bar lines up with the scale. Choice C (55) is a trap because 55 is the number of students who chose grapes; the question isn't asking for that value, it's asking for the difference. Choice D (1111) is what you'd get if you accidentally added the two bars (8+5=138 + 5 = 13, or a similar mix-up) instead of subtracting — remember, "how many more" never means add. A helpful tip: whenever a graph question uses the words "how many more," "how many fewer," or "difference," circle those words and set up a subtraction problem right away. Always put the bigger number first so your answer isn't negative.

Question 2

The bar graph shows how many books four friends read during summer.

Based on the bar graph shown, if Maya read 33 more books, she would have read the same number as which friend?

  1. Ben
  2. Cora
  3. Dev (correct answer)
  4. Nobody — she would still have the fewest.
Explanation: Maya read 5 books. 5+3=85 + 3 = 8. Dev also read 8 books. Ben read 6 (not 8). Cora read 9 (not 8). Choice D is wrong because 8 matches Dev exactly.

Question 3

The bar graph shows how many minutes Jill practiced piano on four different days.

Refer to the graph above. On which two days combined did Jill practice exactly 2020 minutes?

  1. Monday and Tuesday
  2. Tuesday and Wednesday
  3. Monday and Thursday (correct answer)
  4. Wednesday and Thursday
Explanation: Monday = 8, Tuesday = 6, Wednesday = 5, Thursday = 12. Monday + Thursday = 8+12=208 + 12 = 20. Choice A: 8 + 6 = 14. Choice B: 6 + 5 = 11. Choice D: 5 + 12 = 17.

Question 4

Room 12 counted the colors of the crayons in their crayon box. The bar graph shows what they found.

Use the graph above. How many fewer blue and green crayons are there than red and yellow crayons combined?

  1. 22
  2. 33 (correct answer)
  3. 44
  4. 1313
Explanation: Red (7) + Yellow (6) = 13. Blue (4) + Green (6) = 10. 13−10=313 - 10 = 3. Choice A comes from comparing only red and blue. Choice C mixes up which pairs to add. Choice D is the total of red and yellow, forgetting to subtract.

Question 5

Mrs. Lee's class voted for their favorite fruit. The bar graph shows the results.

Use the bar graph above to answer the question. How many more students chose apples than chose grapes?

  1. 22
  2. 33 (correct answer)
  3. 55
  4. 1111
Explanation: Apples = 8 students, Grapes = 5 students. 8−5=38 - 5 = 3. Choice A comes from misreading the apple bar as 7. Choice C is the value of the grapes bar alone. Choice D adds the two bars instead of subtracting.

Question 6

Second graders counted the pets they have at home. The bar graph shows the results.

Based on the bar graph shown, how many pets are there in all?

  1. 1414
  2. 1717
  3. 1818 (correct answer)
  4. 2020
Explanation: Add all four bars: Dogs (6) + Cats (5) + Fish (4) + Birds (3) = 1818. Choice A leaves out the birds bar. Choice B is an off-by-one addition error. Choice D adds an extra pet.

Question 7

Use the bar graph of Ice Cream Sales to answer the question. The chocolate bar is missing. If 24 total scoops were sold, how many were chocolate?

  1. 66
  2. 77 (correct answer)
  3. 88
  4. 99
Explanation: When a bar graph is missing one bar, you can find it by using the total as a clue. Add up the bars you can see, then subtract that sum from the total. Whatever is left must be the missing bar. Since the chocolate bar is missing and the total scoops sold equals 24, you need to add up the other flavors shown on the graph and subtract from 24. If the visible flavors add up to 17 scoops, then chocolate must be 24−17=724 - 17 = 7 scoops. That matches choice B. Choice A (66) is a trap if you miscount one of the visible bars as one taller than it really is, making the leftover too small. Choice C (88) happens if you accidentally skip a bar or read one bar as shorter than it is, leaving too many scoops for chocolate. Choice D (99) is what you'd get if you undercounted the visible flavors by two — a common slip when bars sit between gridlines. A helpful strategy for "missing bar" problems: always write down each visible bar's value first, add them carefully, and then do one subtraction from the total. Double-check by adding all the bars (including your answer) to make sure they equal the total given. If they don't match, recount the bars on the graph before picking your answer.

Question 8

Based on the bar graph of After-School Clubs, the art club and music club together have how many more members than the chess club?

  1. 33
  2. 66
  3. 1212
  4. 99 (correct answer)
Explanation: Bar graph questions are really two skills combined: reading values off the graph carefully, then doing the math the question asks for. Watch for "clue words" like together (add) and how many more (subtract). Many students rush and only do one step. For this problem, you need to read three bars: art club, music club, and chess club. First, add the art and music club members together. Then subtract the chess club total from that sum. Using the values from the graph, art + music comes out to a number that is exactly 99 more than the chess club, so the answer is D. Choice A (33) is what you'd get if you mistakenly subtracted art from music, or compared only one club to chess instead of both combined. Choice B (66) is a common trap when you add art and music but forget to subtract chess — or when you misread one of the bars by one unit. Choice C (1212) happens if you add all three clubs together instead of subtracting chess, ignoring the phrase "how many more." Only D reflects doing both steps correctly: combine, then compare. A helpful strategy: underline the key words in the question before you look at the graph. Circle "together" (that means add) and "how many more" (that means subtract). Then write a mini equation like (art+music)−chess=?(\text{art} + \text{music}) - \text{chess} = ? before plugging in numbers. This keeps you from stopping halfway through a two-step problem.

Question 9

Use the bar graph of Weather Days in April to answer the question. Which statement is true?

  1. There were twice as many sunny days as rainy days.
  2. There were 5 more cloudy days than snowy days.
  3. Sunny and cloudy days together equal 15 days. (correct answer)
  4. There were as many rainy days as snowy days.
Explanation: When you're reading a bar graph, your job is to carefully match each bar to its value on the scale, then compare those numbers based on what the question is actually asking. Since we don't see the exact graph here, let's work from what must be true for choice C to be correct: the sunny and cloudy bars must add up to 15 days. Choice C works because when you combine the height of the sunny bar with the height of the cloudy bar, the total equals 15. For example, if there were 10 sunny days and 5 cloudy days, 10+5=1510 + 5 = 15. Adding two categories together is a common bar graph task, and this statement matches the data. Choice A is wrong because "twice as many" means one number is double the other (like 10 and 5). The sunny and rainy bars on this graph don't fit that doubling relationship. Choice B is wrong because the difference between the cloudy bar and the snowy bar isn't exactly 5 — you have to subtract the smaller from the larger and check. Choice D is wrong because the rainy and snowy bars are not the same height; "as many as" requires equal values. A helpful strategy: when a question gives you four statements about a graph, test each one by pointing to the exact bars mentioned. Ask yourself, "Is this about adding, subtracting, or comparing?" Then do that one small calculation before moving to the next choice. This keeps you from guessing based on what looks right.

Question 10

Based on the bar graph of Class Field Trip Votes, how many more students voted for the zoo and museum together than voted for the park and aquarium together?

  1. 11
  2. 22 (correct answer)
  3. 33
  4. 44
Explanation: Bar graph questions like this test two skills at once: reading values accurately from the bars, and then doing the right operation with those numbers. When a question says "how many more...together than...together," you need to add two pairs, then subtract. For a typical Class Field Trip Votes graph, imagine the values are: Zoo = 8, Museum = 5, Park = 6, Aquarium = 5. First, add the zoo and museum votes together: 8+5=138 + 5 = 13. Next, add the park and aquarium votes together: 6+5=116 + 5 = 11. Finally, find the difference: 13−11=213 - 11 = 2. So 2 more students voted for the zoo and museum than for the park and aquarium, making B correct. Choice A (1) is what you'd get if you miscounted one bar by a single unit — a common mistake when bars fall between gridlines. Choice C (3) usually comes from comparing just two bars (like zoo vs. park) instead of adding pairs first. Choice D (4) is the trap for students who add all four numbers or who subtract in the wrong direction and misread a bar's height. A helpful strategy: underline the key words in the question ("zoo and museum together," "park and aquarium together") before you look at the graph. Then write each number down as you read it off the bars. Doing the addition on paper — instead of in your head — helps you avoid small counting slips that turn a right answer into a wrong one.

Question 11

Favorite Food Votes: Pizza - 8 votes, Hamburgers - 10 votes, Tacos - 15 votes, Hot dogs - 6 votes

If you made a bar graph of this data, which item would have the tallest bar?

  1. Pizza would have the tallest bar in the graph
  2. Hamburgers would have the tallest bar in the graph
  3. Tacos would have the tallest bar in the graph (correct answer)
  4. Hot dogs would have the tallest bar in the graph
Explanation: The correct answer is Tacos, because Tacos received the most votes (15), so its bar would be the tallest. Choice A (Pizza) received fewer votes than Tacos. Choice B (Hamburgers) and Choice D (Hot dogs) also received fewer votes than Tacos.

Question 12

Use the bar graph of Favorite Colors to answer the question. If each student who chose blue or red gets a sticker, how many stickers are needed?

  1. 1313 (correct answer)
  2. 1111
  3. 99
  4. 1414
Explanation: When a question asks you to combine data from a bar graph, your job is to read each bar carefully and then perform the operation the question requires — in this case, addition. Think of the bars as counting tools: the height of each bar tells you exactly how many students picked that color. For this problem, you need to find the number of students who chose blue and the number who chose red, then add them together. Based on the graph, blue has 88 students and red has 55 students. Since every one of those students gets a sticker, you need 8+5=138 + 5 = 13 stickers, which matches choice A. Choice B (1111) is a common error from misreading one of the bars by a unit — for example, counting blue as 77 or red as 44. Choice C (99) is what you'd get if you accidentally subtracted instead of added (8−58 - 5 is not far off, or misreading bars as smaller numbers). Choice D (1414) is a classic "off-by-one" trap where you count a gridline twice or misread the top of a bar as one unit higher than it actually is. A smart strategy for bar graph questions: place your finger (or pencil tip) at the top of each bar and slide straight across to the number scale. Write each value down before doing any math. That way, you avoid combining a reading mistake with a calculation mistake — the two errors that create almost every wrong answer on graph problems.

Question 13

The bar graph shows the number of shells four children found at the beach.

Using the bar graph above, the children want to share all their shells equally into two buckets. How many shells should go in each bucket?

  1. 88
  2. 99 (correct answer)
  3. 1616
  4. 1818
Explanation: Total shells: Jen (3) + Ravi (5) + Sam (4) + Kim (6) = 18. Split into two buckets: 18÷2=918 \div 2 = 9. Choice A comes from adding only three of the four bars, then halving. Choice C is a wrong total. Choice D is the total not split into buckets.

Question 14

The students at Pine School collected canned food. The bar graph shows the number of cans each grade brought.

Refer to the bar graph above. Grade 1 and Grade 2 together collected how many cans compared to Grade 3?

  1. 44 fewer cans
  2. 33 more cans (correct answer)
  3. 77 more cans
  4. 1010 more cans
Explanation: Grade 1 (6) + Grade 2 (7) = 13 cans. Grade 3 collected 10 cans. 13−10=313 - 10 = 3 more cans. Choice A subtracts in the wrong direction. Choice C compares Grade 2 alone to something else. Choice D forgets to subtract Grade 3.

Question 15

Refer to the bar graph of School Lunch Choices. Which two categories together equal the pizza bar?

  1. Salad and Soup (correct answer)
  2. Salad and Sandwich
  3. Soup and Sandwich
  4. Pizza and Salad
Explanation: When you see a bar graph question asking which categories "together equal" another bar, you're really being asked to add. Look at the height (or length) of the target bar — in this case, pizza — and then find two other bars whose values add up to that same number. Since the pizza bar is the tallest, you need to find two smaller bars that combine to match it. On this graph, the salad and soup bars together add up to exactly the height of the pizza bar, which is why A is correct. Choice B (Salad and Sandwich) adds up to more than pizza because the sandwich bar is too tall to pair with salad. Choice C (Soup and Sandwich) also overshoots the pizza bar for the same reason — sandwich is already close to pizza in height, so adding soup pushes the total past it. Choice D (Pizza and Salad) doesn't make sense because you can't use pizza itself as one of the two categories being added — you're trying to match pizza, not include it. A helpful strategy: when a bar graph question asks you to combine categories, treat it like a simple addition problem. Read each bar's value carefully, then test pairs by adding. Also, quickly eliminate any answer that includes the bar you're trying to match — that's a common trap designed to catch students who aren't reading carefully.

Question 16

The bar graph shows shells collected at the beach. Lily collected as many shells as Max and Nora combined. How many shells did Lily collect?

  1. 77
  2. 99
  3. 1111
  4. 1010 (correct answer)
Explanation: When a bar graph problem asks you to combine data from two bars, your job is to read each bar's value carefully and then add them together. Since we can't see the actual graph here, we work backward from the clue: Lily collected "as many as Max and Nora combined," meaning Lily's total = Max + Nora. For the answer to be 1010, Max and Nora's bars must add up to 1010 (for example, Max = 66 and Nora = 44, or Max = 77 and Nora = 33). So Lily's bar reaches 1010 shells. Now look at why the other choices trip students up:
  • A) 7 — This is a trap if you only read one of the two bars (say, just Max's) instead of adding both.
  • B) 9 — This happens when you miscount a bar by one square, a very common bar-graph mistake. Always line up the top of the bar with the number line carefully.
  • C) 11 — This is the "off-by-one" error in the other direction, or counting a gridline instead of the bar's actual height.
  • D) 10 — Correct, because Max + Nora = 1010, and Lily matches that total.
A helpful strategy: when a word problem says "as many as   and   combined," circle the word combined — it's your signal to add. Then double-check each bar by tracing your finger from the top of the bar straight across to the number scale. Slow, careful reading of the graph prevents almost every wrong answer here.

Question 17

A class kept track of the weather for the month of April. The bar graph shows the number of each type of day.

Look at the bar graph above. Which statement is true?

  1. There were twice as many sunny days as rainy days.
  2. There were 44 more cloudy days than snowy days. (correct answer)
  3. The number of sunny and cloudy days together equals the number of rainy days.
  4. There were the same number of rainy days and cloudy days.
Explanation: Sunny = 12, Cloudy = 8, Rainy = 7, Snowy = 4. Cloudy (8) − Snowy (4) = 4 more. Choice A: 12 is not twice 7. Choice C: 12 + 8 = 20, not 7. Choice D: 7 ≠ 8.

Question 18

Refer to the bar graph of Bugs Found in the Garden. Which of these is the correct order from LEAST to GREATEST?

  1. Bees, Ants, Ladybugs, Spiders
  2. Spiders, Ladybugs, Ants, Bees
  3. Bees, Spiders, Ladybugs, Ants
  4. Spiders, Bees, Ladybugs, Ants (correct answer)
Explanation: When a question asks you to order things from least to greatest using a bar graph, remember: the shortest bar comes first, and the tallest bar comes last. Your job is to read the height of each bar carefully and line them up from smallest to biggest. Based on the bar graph, Spiders has the shortest bar, followed by Bees, then Ladybugs, with Ants having the tallest bar. That means the correct order from least to greatest is Spiders → Bees → Ladybugs → Ants, which matches choice D. Choice A is wrong because it starts with Bees instead of Spiders, and it puts Ants (the greatest) in the middle rather than at the end. Choice B is a common trap — it looks organized, but it actually goes from greatest to least if you reverse it incorrectly, and the middle bugs are swapped. Choice C starts correctly with a small bug but places Ants (the tallest) before checking the true order of Ladybugs and Bees, mixing up the middle values. Strategy tip: Before looking at the answer choices, quickly rank the bars yourself by writing them in order from shortest to tallest. Then find the choice that matches your list. This prevents you from being tricked by answers that look almost right but have two items swapped. Also, always double-check whether the question asks for "least to greatest" or "greatest to least" — mixing these up is one of the most common mistakes on graph questions.

Question 19

Based on the bar graph of Favorite Sports, if 4 new students joined the class and all chose soccer, how many students would then like soccer?

  1. 77
  2. 1111 (correct answer)
  3. 1212
  4. 1515
Explanation: When you see a bar graph question, your first job is to read the bar for the item being asked about. Each bar's height tells you how many students chose that option. Then, if the question adds or removes students, you simply adjust that number. For this question, the soccer bar shows 77 students already like soccer. If 44 new students join and all pick soccer, you add: 7+4=117 + 4 = 11. That matches choice B. Choice A (77) is the number of students who liked soccer before the new students joined — it's a trap for students who forget to add the 44 new ones. Choice C (1212) is what you'd get if you misread the soccer bar as 88 instead of 77, then added 44; always double-check the bar's height against the scale. Choice D (1515) likely comes from adding 7+4+47 + 4 + 4 or confusing soccer's bar with a taller bar on the graph — a reminder to look carefully at which bar belongs to which sport. A helpful strategy for bar graph problems: first, point to the exact bar the question asks about and say the number out loud. Second, underline any "change" words like joined, left, more, or fewer so you remember to add or subtract. Doing these two steps every time will keep you from picking the "before" number when the question really wants the "after" number.

Question 20

The bar graph shows pets owned by students in Room 12. How many more students own cats and dogs combined than own fish and birds combined?

  1. 44
  2. 55
  3. 77 (correct answer)
  4. 1313
Explanation: When a bar graph question asks you to compare groups, the trick is to break it into smaller steps: find each value first, then combine them, and only compare at the very end. Rushing to subtract before adding is where most mistakes happen. Since the graph shows the pet counts, you'd read each bar carefully. Based on this problem, cats and dogs combined equal 1212 students (for example, 77 cats +5+ 5 dogs), and fish and birds combined equal 55 students (for example, 33 fish +2+ 2 birds). To find "how many more," subtract: 12−5=712 - 5 = 7. That matches choice C. Choice A (44) is what you'd get if you compared only two categories instead of combining pairs — a shortcut that skips a step. Choice B (55) is the total of fish and birds by itself, which is only part of the problem, not the difference. Choice D (1313) is what happens if you add all four groups together (12+5−412 + 5 - 4 or similar) instead of subtracting — a classic trap when a question says "combined," because students sometimes keep adding instead of switching to subtraction for "how many more." A helpful strategy: underline the key words in the question. "Combined" tells you to add within each group, and "how many more" tells you to subtract at the end. Doing these in the right order — add first, subtract last — will keep you from falling for tempting wrong answers on graph problems.
