Try each quiz question before looking at the correct answer. Use the explanations to review missed ideas, then come back to similar questions until the pattern feels familiar.

All questions

Question 1

Use the number line to answer this question. Start at the number 8. Count forward 6 more numbers. Then count backward 3 numbers. What number are you at now?

  1. You are now at the number 11 (correct answer)
  2. You are now at the number 17
  3. You are now at the number 14
  4. You are now at the number 12
Explanation: Starting at 8, counting forward 6 numbers: 8 + 6 = 14. Then counting backward 3 numbers: 14 - 3 = 11. Choice B (17) represents only adding 8 + 6 + 3 without subtracting. Choice C (14) represents stopping after the forward count. Choice D (12) represents a common off-by-one error in the final calculation.

Question 2

Look at the two lines of buttons. The top line has red buttons and the bottom line has blue buttons. How many more red buttons are there than blue buttons?

  1. There are 3 more red buttons than blue buttons (correct answer)
  2. There are 5 more red buttons than blue buttons
  3. There are 2 more red buttons than blue buttons
  4. There are 4 more red buttons than blue buttons
Explanation: The top line has 12 red buttons and the bottom line has 9 blue buttons. To find how many more red buttons there are, subtract: 12 - 9 = 3. Choice B (5) might come from miscounting one of the lines. Choice C (2) represents an off-by-one error in subtraction. Choice D (4) represents a different miscounting error.

Question 3

Count the total number of shapes in both groups shown. Then count only the circles in both groups. How many shapes are NOT circles?

  1. There are 12 shapes that are NOT circles (correct answer)
  2. There are 8 shapes that are NOT circles
  3. There are 15 shapes that are NOT circles
  4. There are 10 shapes that are NOT circles
Explanation: Group 1 has 10 shapes (4 circles, 3 triangles, 3 squares). Group 2 has 8 shapes (2 circles, 3 triangles, 3 squares). Total shapes: 18. Total circles: 6. Shapes that are NOT circles: 18 - 6 = 12. Choice B (8) represents only counting one group. Choice C (15) represents miscounting the total shapes. Choice D (10) represents counting only the shapes in Group 1.

Question 4

Use the array to solve this problem. Count all the hearts in the array. If 4 hearts were removed from the array, how many hearts would be left?

  1. There would be 11 hearts left in the array (correct answer)
  2. There would be 19 hearts left in the array
  3. There would be 12 hearts left in the array
  4. There would be 10 hearts left in the array
Explanation: The array contains 15 hearts arranged in 3 rows of 5. If 4 hearts are removed, then 15 - 4 = 11 hearts remain. Choice B (19) incorrectly adds 15 + 4. Choice C (12) represents an off-by-one error in subtraction. Choice D (10) represents subtracting 5 instead of 4.

Question 5

Count the objects in the scattered group shown. If you put these objects into groups of 4, how many complete groups of 4 can you make?

  1. You can make exactly 3 complete groups of 4 (correct answer)
  2. You can make exactly 4 complete groups of 4
  3. You can make exactly 2 complete groups of 4
  4. You can make exactly 5 complete groups of 4
Explanation: There are 14 objects in the scattered group. When dividing 14 by 4, we get 3 complete groups of 4 (3 √ó 4 = 12) with 2 objects remaining. Choice B (4) would require 16 objects. Choice C (2) represents undercounting the objects or confusion about division. Choice D (5) would require 20 objects.

Question 6

Look at the circle of stickers below. Emma wants to give away exactly half of these stickers to her friend. After giving away half, how many stickers will Emma have left for herself?

  1. Emma will have 8 stickers left for herself (correct answer)
  2. Emma will have 9 stickers left for herself
  3. Emma will have 7 stickers left for herself
  4. Emma will have 6 stickers left for herself
Explanation: The circle contains 16 stickers total. Half of 16 is 8, so Emma gives away 8 stickers and keeps 8 stickers for herself. Choice B (9) represents a miscounting of the original total or confusion about what 'half' means. Choice C (7) represents an off-by-one error. Choice D (6) represents giving away 10 stickers instead of 8.
