Introduction to Multiplication — Answer Key

1. Sort each sentence into the correct category.
Repeated Addition
2 + 2 + 25 + 5 + 5 + 54 + 4 + 4 Multiplication Sentence
3 x 42 x 76 x 2 Repeated addition writes the same number added over and over. A multiplication sentence uses the x symbol to show the same idea in a shorter way.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 3 + 3 + 3 is the same as 3 x 3.
The number 3 is added 3 times, so it is 3 x 3.
2. 4 x 2 means 4 groups of 2.
The second number tells how many are in each group. 4 x 2 means 4 groups of 2.
3. 5 + 5 + 5 + 5 equals 5 x 4.
The number 5 is added 4 times, so it equals 5 x 4.
4. 2 x 7 equals 14.
2 x 7 means 2 groups of 7, which is 7 + 7 = 14.
5. 6 + 6 is the same as 2 x 6.
The number 6 is added 2 times, so it is 2 x 6.
