Decimal Add Model

Consider the area models. What is the value of the expression modeled by the area models?

• 1.59

• 2.73

• 3.24

• 4.41

Solve using the models.

• 0.85

• 0.75

• 0.41

• 0.39

Which model represents the sum of 0.6 + 0.03?

• 
• 
• 
• 

Use the models to find the difference.

• 0.42

• 0.48

• 0.52

• 0.58

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

0.8 + 0.09 =

• 0.89

• 0.017

• 0.17

• 0.809

Add.

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

0.32 + 0.4 =

• 0.72

• 0.36

• 3.24

• 0.34

• 2.85

• 3.87

• 3.85

• 2.87

• 7.08

• 7.18

• 5.67

• 6.98

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
