We'll be moving to a brand new standard! This week I'll introduce NBT.2.4 which says students should be able to "add and subtract multi-digit whole numbers using the standard algorithm." To work on this standard, we'll be discussing strategies to help up add and subtract, such as counting on, counting up, using doubles and near doubles. We'll also work on regrouping and adding numbers that are multiples off 10, 100, 1,000, etc.

To help your child with this standard, you can make up some problems and see if they can solve it. For example: 45,392 + 39, 795.
Happy Adding and Subtracting!
