Introduction to Multiplication — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 4 x 3 equals 12.
4 x 3 means 4 groups of 3, which is 3 + 3 + 3 + 3 = 12.
2. 2 + 2 + 2 + 2 + 2 is the same as 5 x 2.
The number 2 is added 5 times, so it is 5 x 2.
3. 3 groups of 5 equals 15.
3 groups of 5 means 5 + 5 + 5 = 15.
4. 5 x 4 equals 20.
5 x 4 means 5 groups of 4, which is 4 + 4 + 4 + 4 + 4 = 20.
5. 6 + 6 + 6 is the same as 3 x 6.
The number 6 is added 3 times, so it is 3 x 6.
6. 2 x 8 equals 16.
2 x 8 means 2 groups of 8, which is 8 + 8 = 16.
7. 4 + 4 + 4 + 4 is the same as 4 x 4.
The number 4 is added 4 times, so it is 4 x 4.
8. 3 x 3 equals 9.
3 x 3 means 3 groups of 3, which is 3 + 3 + 3 = 9.
9. 7 + 7 is the same as 2 x 7.
The number 7 is added 2 times, so it is 2 x 7.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
2 + 2 + 2
→ 3 x 2
4 x 5
5 + 5 + 5 + 5
→ 4 x 5
3 x 4
3 + 3
→ 2 x 3
3 x 2
4 + 4 + 4
→ 3 x 4
2 x 3
Count how many times the number is added. 2+2+2 is 2 added 3 times = 3 x 2. 5+5+5+5 is 5 added 4 times = 4 x 5. 3+3 is 3 added 2 times = 2 x 3. 4+4+4 is 4 added 3 times = 3 x 4.
