Mental math is math you do inside your head. We have been working on our mental math skills in the classroom. The boy and girls should practice mental math at home. Once they solve the answer they should be able to show or articulate what they did to solve.
For example:
28 + 36 = 64
I turned 28 into 30 by giving two of the ones from 36. That gave me 30 + 34.
30 + 30 is 60. Plus 4 more ones is 64.
