Repeated Addition as Multiplication Up to 99
See how adding the same number over and over is really just multiplication, worked through with equal groups and numbers up to 99.
What You'll Learn
Recognize that adding the same number several times, such as \( 5 + 5 + 5 + 5 \), is repeated addition
Rewrite a repeated addition sum as a multiplication statement, since \( 5 + 5 + 5 + 5 = 4 \times 5 \)
Identify the number of equal groups and the size of each group before writing the multiplication
Write a general pattern such as \( g + g + g = 3 \times g \), using a letter to stand for the group size
Check answers by counting the addends and comparing the sum to the product for totals up to 99
Connect repeated addition to arrays and skip counting to build fluency with larger multiplication facts
What You'll Practice
1
Describing models using repeated addition and multiplication
2
Converting addition statements to multiplication form
3
Counting dots in arrays to write multiplication equations
Why This Matters
Understanding repeated addition as multiplication builds the foundation for all multiplication skills you'll need throughout math. This connection helps you solve problems faster, understand area and grouping in real life, and prepares you for division, fractions, and algebra.
