Multiply Decimals by Decimals, Modeling and Expressions

If a 100 block acts as a 1, then what decimal expression is being shown in this model?

• 1

• 0.1

• 9

• 0.9

If a 100 block acts as a 1, then what decimal expression is being shown in this model?

• 7

• 0.7

• 3

• 0.3

Based on the last questions, what expression would best fit this current picture?

• 0.9 + 0.3

• 0.9 x 0.3

• 0.9 - 0.3

• 0.9 / 0.3

Based on the previous questions, what would be the area shaded in green?

• 27 units

• 60 units

• 90 units

• 93 units

What would be another way to write 0.9 x 0.3 = 0.27

• .9 x .3 = 27

• .9 x .3 = 27 ÷ 10

• .9 x .3 = 27 ÷ 100

• .9 x .3 = 27 ÷1,000

If a 100 block acts as a 1, then what decimal expression is being shown in this model?

• 4

• 0.4

• 5

• 0.5

If a 100 block acts as a 1, then what decimal expression is being shown in this model?

• 4

• 0.4

• 6

• 0.6

Based on the last questions, what expression would best fit this current picture?

• 0.5 + 0.6

• 0.5 x 0.6

• 0.5 - 0.6

• 0.5 / 0.6

Based on the previous questions, what would be the area shaded in green?

• 30 units

• 50 units

• 70 units

• 80 units

What would be another way to write 0.5 x 0.6 = 0.30

• .5 x .6 = 30

• .5 x .6 = 30 ÷ 10

• .5 x .6 = 30 ÷ 100

• .5 x .6 = 30 ÷1,000
