(G7M3L4) Concept Development: The Distributive Property allows you to rewrite specific expressions involving multiplication and addition/subtraction without changing the value of the expression. Examples: Non.Examples: 8 ! + 5 = 8 ! + 8 5 = 8! + 40 8 ! + 5 = 8! + 5 3 2! 5 = 3 2! 3 5 = 6! 15 Using an Array Model to Show the Distributive Property How can we use a tape diagram to represent ! + 2? What about 4(! + 2) Example: 3 ! + 3 Non.Example: 3(! + 3)

Examples:**

Non.Examples:*

'8 ! + 5 = 8 ∙ ! + 8 ∙ 5 = 8! + 40'

'8 ! + 5 = 8! + 5'

''

3 2! − 5 = 3 ∙ 2! − 3 ∙ 5 = 6! − 15''
