Steps:
1. Circle the greater factor.
2. Write the greater factor in expanded
form above the area model.
3. Write the lesser factor on the outer
left side of the area model.
4. Write each equation in the corre-
sponding place value section and
find the product of each.
5. Add the products to solve.
Area model:
479 × 8 =
400 + 70 + 9
8 400 × 8 = 3200 70 × 8 = 560 9 × 8 = 72
400 × 8 = 3,200
70 × 8 = 560
+ 9 × 8 = 72
3,832
Factors: numbers that are multiplied to
create a product
Product: the result of multiplying factors
together
