Addition Tuesday

Last week we started to add 3 numbers together.  Remember – you can add numbers in any order, the answer will always be the same.

When you are adding 3 numbers, look for easy numbers to add together first:

• numbers that add to 10, then add the last number

• look for doubles and near doubles to help you add

• start with the largest number and add on the smaller numbers

Warm Up:
