    Overview: Strategies for Mental Math

    Estimated Time: Approximately 45 minutes


    You can use mental math strategies to add 2-digit numbers


    Quick things to know:

    1. When no regrouping is needed, separate the smaller number by place value. Subtract the tens, then subtract the ones.
    2. When regrouping IS required, subtract a “close” number and add the extra back (because you subtracted too many).
    3. You don’t always need paper and pencil if you use mental math strategies.


    1. Complete the BLUE Math in Focus packet pages 3 and 4.


     Keep your work in a folder and you may turn it in when you come back to school.
