OPERATIONS WITH DECIMALS

Using Base Ten Blocks to Multiply Decimals Flat = one (1) Long = one tenth (0.1) rod = one hundredth (0.01)

Multiplying Decimals by Whole Numbers Tenths

Multiply 5 x 0.3 Shade in 0.3 five times using a different color each time. 5 x 0.3 = 1.5

4 x 0.6 4 x 0.6 = 2.4

3 x 0.7 Shade in 0.7 three times using a different color each time. 3 x 0.7 = 2.1

On Your Own Use tenth grids to do the following problems: 1. 2 x 0.92. 3 x 0.7 3. 9 x 0.24. 10 x 0.3 5. 7 x 0.56. 8 x 0.8

Multiplying Decimals by Whole Numbers Using Models Hundredths

Multiply 4 x 0.19 Shade 0.19 four times. 4 x 0.19 = 0.76

Multiply 5 x 0.25 Shade 0.25 five times. 5 x 0.25 = 1.25

Multiply 3 x.35 3 x.35 = 1.05

On Your Own Use hundredth grids do the following problems: 1. 4 x 0.632. 6 x 0.19 3. 2 x 0.944. 7 x 0.51
