Multiply Decimal Numbers using Number Bonds 5-105

Use number bonds to multiply by applying the distributive property. Find and add partial products to get the total products. What's 2 x 35.46? Since 2 x 30 = 60, 2 x 5 = 10, 2 x .40 = .80, 2 x.06 = .12, and 60 + 10 + .80 + .12 = 70.92. Leverage understanding of fractions and the area model to multiply and make sense of decimals.
