    Overview: More Strategies for Mental Math

     

    Estimated Time: Approximately 45 minutes

     

    Explanation:  

    When adding numbers close to 100, add 100 and then subtract the extra ones.

     

    Quick things to know:

    1. Look for the higher number … the number closer to 100.
    2. Count from that number up to 100. Then subtract those extra ones. 

    *Look at the example on the top of page 5 in your blue packet.

    1. You don’t always need paper and pencil if you use mental math strategies.

     

    Tasks:

    1. Complete the BLUE Math in Focus packet pages 5 and 6.

     

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