Lesson: Finding the Missing Number

Tip: Think PART- PART- WHOLE! whole - part = part ___ - 2 = 10 We are trying to find the missing WHOLE. We have two parts. To find the missing whole, let’s ADD the parts we do know! 2 + 10 = 12 So now put the 12 in front! 12 - 2 = 10 Our missing number was 12! CHECK YOUR WORK: Are both sides equal? Are my muscles equal? __- 2 = 10 12-2=10 10 = 10
