“when a number is added and subtracted by the same number, the result is the original number”

OBJECTIVE(S): Feb. 23, 2015Module 4

SWBAT: recognize when a number is added and subtracted by the same number, the result is the original number (Lesson 1)

a + b – b = a or b – b + a = a

recognize when a number is multiplied and divided by the same number, the result is the original number (Lesson 2)

a ÷ b b= a or a b ÷ b = a
