Represent Decimal Addition Using Concrete Models or Drawings

Which problem is represented in the model?

• 0.32 - 0.17

• 0.49 - 0.32

• 0.32 + 0.17

• 0.49 - 0.17

Which equation matches the model?

• 0.73 - 0.23 = 0.50

• 0.50 + 0.23 = 0.73

• 0.73 + 0.23 = 0.50

• 0.73 - 0.50 = 0.23

What equation matches this model?

• 0.32 + 0.17 = 0.49

• 0.32 - 0.17 = 0.49

• 0.49 - 0.17 = 0.32

• 0.49 + 0.17 = 0.32

What equation matches this model?

• 0.7 - 0.44 = 1.14 

• 1.14 - 0.44 = 0.7

• 1.14 + 0.7 = 0.44

• 0.7 + 0.44 = 1.14

Add.

You may use the models shown to help find the sum.

0.32 + 0.4 =

• 0.72

• 0.36

• 3.24

• 0.34

The decimal grids below are shaded to model an expression. What is the value of the expression modeled by the decimal grids ?

• 3.29

• 3.32

• 4.10

• 4.13
