Introduction to Multiplication — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 7 groups of 2 equals 14.
Seven groups of 2 is 2 + 2 + 2 + 2 + 2 + 2 + 2, which totals 14. Skip counting by 2s seven times also lands on 14.
2. 3 + 3 + 3 + 3 + 3 is the same as 5 x 3.
Count how many 3s are being added: there are five 3s. That matches 5 x 3.
3. 4 x 6 equals 24.
4 x 6 means 6 + 6 + 6 + 6, which equals 24. Skip counting by 6s four times also reaches 24.
4. 8 + 8 + 8 is the same as 3 x 8.
Three 8s are being added together, and 'three groups of 8' is written as 3 x 8. Both equal 24.
5. 6 groups of 5 equals 30.
Six groups of 5 can be counted by 5s: 5, 10, 15, 20, 25, 30. The total is 30.
6. 2 x 9 equals 18.
2 x 9 means 9 + 9, which equals 18. Doubling 9 is a quick way to find it.
7. 10 + 10 + 10 is the same as 3 x 10.
There are three 10s in the sum, so this is three groups of 10. That matches 3 x 10, which is 30.
8. 5 x 5 equals 25.
5 x 5 is five groups of 5, which is 5 + 5 + 5 + 5 + 5. Skip counting by 5s five times gives 5, 10, 15, 20, 25.
9. 9 + 9 is the same as 2 x 9.
Two 9s are being added, so this is two groups of 9. That is written as 2 x 9, which equals 18.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
6 + 6 + 6 + 6
→ 24
25
7 + 7 + 7
→ 21
8
5 + 5 + 5 + 5 + 5
→ 25
21
4 + 4
→ 8
24
Count how many times each number repeats to turn addition into multiplication: four 6s = 24, three 7s = 21, five 5s = 25, and two 4s = 8.
