Introduction to Multiplication — Answer Key
Part A: Sort the Words
Sort each word or number into the correct category box.
1. Sort each sentence into the correct category.
Multiplication (Equal Groups)
2 x 35 x 12 x 6 Not Multiplication
4 + 23 + 78 - 3 Multiplication means equal groups. When items are split into groups of the same size, that is multiplication. Adding two different numbers or subtracting is not multiplication.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 3 groups of 4 means 3 x 4.
In 3 groups of 4, the number after 'of' tells how many are in each group. So 3 x 4.
2. 2 x 5 means 2 groups of 5.
The first number in a multiplication sentence tells how many groups. 2 x 5 means 2 groups of 5.
3. 4 groups of 2 equals 8.
4 groups of 2 means 2 + 2 + 2 + 2 = 8.
4. 5 x 3 means 5 groups of 3.
The second number tells how many are in each group. 5 x 3 means 5 groups of 3.
5. 1 x 6 means 1 group of 6.
The first number tells how many groups. 1 x 6 means 1 group of 6.
Part C: True or False?
Read each statement. Circle True or False.
1. 4 x 3 means 4 groups of 3.
True False
True. The first number is how many groups and the second number is how many in each group.
2. 3 + 3 + 3 is the same as 3 x 3.
True False
True. Adding 3 three times is the same as 3 groups of 3, which is 3 x 3.
3. 2 x 6 equals 14.
True False
False. 2 x 6 means 2 groups of 6, which is 6 + 6 = 12, not 14.
4. 5 groups of 2 equals 10.
True False
True. 5 groups of 2 means 2 + 2 + 2 + 2 + 2 = 10.
