Find the quotient:
72 \({ \div }\) 8 \({ = }\) ?
- 9
- 7
- 6
- 8
This is correct! 72 \({ \div }\) 8 = 9.
This is incorrect. 8 \({ \times }\) 7 = 56, not 72. Remember to think about the multiplication fact that answers 8 times what equals 72?
This is incorrect. Remember that 8 \({ \times }\) 6 = 48. Think about the multiplication fact that answers 8 times what equals 72.
This is incorrect. Remember that 8 \({ \times }\) 8 = 64. Think about the multiplication fact that answers 8 times what equals 72.
Find the quotient:
24 \({ \div }\) 6 \({ = }\) ?
- 8
- 4
- 6
- 5
This is incorrect. Remember that 6 \({ \times }\) 8 \({ = }\) 48. Think about the multiplication fact that answers 6 times what equals 24.
Great job! 24 \({ \div }\) 6 \({ = }\) 4.
This is incorrect. 6 \({ \times }\) 6 \({ = }\) 36. Remember to think about the multiplication fact that answers 6 times what equals 24.
This is incorrect. 6 \({ \times }\) 5 \({ = }\) 30. Think about the multiplication fact that answers 6 times what equals 24.
Which division sentence matches the array?
- 22 \({ \div }\) 10 \({ = }\) 2
- 18 \({ \div }\) 9 \({ = }\) 3
- 20 \({ \div }\) 9 \({ = }\) 3
- 18 \({ \div }\) 9 \({ = }\) 2
This is incorrect. Look at the number of groups and the number in each group again.
This is incorrect. It is the correct number of groups but not the correct number in each group. Look at the number in each group again.
This is incorrect. Count the number of groups and the number in each group. Remember to think of the multiplication fact to help if you need it.
This is correct! There are 9 groups of 2 snowflakes.
Find the quotient:
90 \({ \div }\) 10 \({ = }\) ?
- 9
- 8
- 7
- 10
That is correct! 90 \({ \div }\) 10 \({ = }\) 9.
Try again. 8 \({ \times }\) 10 \({ = }\) 80. Think of the multiplication fact that answers 10 times what equals 90.
Try again. 7 \({ \times }\) 10 \({ = }\) 70. Remember to think of the multiplication fact that answers 10 times what equals 90.
Try again. Remember to think of the multiplication fact that answers 10 times what equals 90.
Which division sentence is represented in the following array?
- 27 \({ \div }\) 9 \({ = }\) 3
- 21 \({ \div }\) 7 \({ = }\) 3
- 24 \({ \div }\) 8 \({ = }\) 3
- 30 \({ \div }\) 10 \({ = }\) 3
This is incorrect. Look at the number of groups and the number in each group.
That is correct! There are 21 helmets divided into 7 groups of 3.
This is incorrect. Count the number of groups and the number in each group again.
This is incorrect. Look at the number of groups and the number of helmets in each group.
Read the word problem below and solve.
Mary is making a schedule for activities she wants to do every day during the 7 days she is on vacation. She has 28 activities she wants to do equally during the 7 days. How many activities should she schedule for each day?
- 4
- 3
- 2
- 5
That is correct! 7 \({ \times }\) 4 \({ = }\) 28, so the quotient is 4. She should schedule 4 activities a day.
Try again. 7 \({ \times }\) 3 \({ = }\) 21. Think about the multiplication fact that answers 7 times what equals 28. That is your quotient.
Try again. 7 \({ \times }\) 2 \({ = }\) 14. Think about the multiplication fact that answers the question 7 times what equals 28.
Try again. 7 \({ \times }\) 5 \({ = }\) 35. Think about the multiplication fact that answers 7 times what equals 28.
Read the word problem below and solve.
Seth has $80 and wants to share his money evenly between him and his 8 friends. How much will each person receive?
- $10
- $8
- $9
- $6
That is correct. 80 \({ \div }\) 8 \({ = }\) 10.
Try again. Remember that 8 \({ \times }\) 8 \({ = }\) 64. Think about the multiplication fact that answers 8 times what equals 80.
Try again. 8 \({ \times }\) 9 \({ = }\) 72. Think about the multiplication fact that answers 8 times what equals 80.
Try again. 8 \({ \times }\) 6 \({ = }\) 48. There are 7 friends plus Seth, which equals 8 people sharing the $80. Think about the number that would answer the question 8 times what equals 80.
Read the word problem below and solve.
16 people will be riding in bobsleds. How many people are in each bobsled if there are 8 bobsleds total?
- 1
- 3
- 2
- 4
This is incorrect. 8 \({ \times }\) 1 \({ = }\) 8. Think about the multiplication fact that answers 8 times what equals 16.
This is incorrect. 8 \({ \times }\) 3 \({ = }\) 24. Think about the number that would solve the problem 8 times what equals 16.
This is correct! 16 \({ \div }\) 8 \({ = }\) 2. 2 people are in each bobsled.
This is incorrect. 8 \({ \times }\) 4 \({ = }\) 32. There are only 16 people riding in the bobsleds. Think about the multiplication fact that would answer 8 times what is equal to 16.
Find the quotient:
81 \({ \div }\) 9 \({ = }\) ?
- 9
- 8
- 10
