- Associative property of addition (lesson 3): the property of operations that says the grouping of addends does not affect the sum; (a + b) + c = a + (b + c)
- Identity Property of Addition (lesson 2): the property of operations that says the sum of any number and 0 is that same number; a + 0 = a
4. Identify the correct definitions and models. Select all that apply. *
o - Commutative property of addition (lessons 3 & 6): the property of operations that says addends can be in any order and it will NOT change the sum; a + b = b + a
o - Distributive property of multiplication over addition (lessons 3 & 4): the property of operations that says multiplying the sum of two or more addends by a number is the same as multiplying the number by each of the addends individually and adding the products; a(b + c) = ab + ac and ab + ac = a(b + c)
- o Identity Property of Multiplication (lesson 6) – the property of operations that says that the product of any number and 1 is that same number; a ∙ 1 = a
