Bears and Squirrels: 2-digit Adding

Remember that expanded form is when you stretch a number out by its place value parts and turn it into an addition sentence?
134 is the same as 100 + 30 + 4.

Explain how you can use expanded form to solve this problem:  24 + 61 =

What is another way that you could solve the same problem?

  5. You can put it in expanded form and solve it.
    First you put it in expanded form like this
    20+4=24 60+1=61.Then you add 2+6=8.then you add
    4+1=5.Then you put 8 and 5.You get 85.

  7. So if I could 20-4=24
    60+1=61 so if I can add them together.
    Then I will add them together.So lets see
    what it eqls so 24+61=85.MB
