2.6

Multiply Decimals  McGraw 58-61 Connections Pg 62-63

Multiply decimals by whole numbers and by decimals.

 

2.7 ** **

Properties of Multiplication McGraw pg 62-65

Use the properties of multiplication and mental math strategies to multiply whole numbers and decimals.

Students distinguish multiplicative comparisons from additive comparisons. Students use the commutative, associative, and distributive properties to show that two expressions are equivalent. They also illustrate properties of operations by showing that two expressions are equivalent (e.g., determining the area in two different ways for a rectangle whose dimensions

are x + 3 by 5).
