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

- 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.
- You don’t always need paper and pencil if you use mental math strategies.
- Complete the BLUE Math in Focus packet pages 5 and 6.
