We have updated to the Everyday Math "aligned to the Common Core," but it is the same old book with Common Core standards marked into each lesson. It will take me a while to decide what to wean out and what to stress so that my classroom gets deep enough into Common Core. Everyday Math naturally does much of the deep thinking, but I want to be sure to go deep enough into the standards.
Anyway, Chapter 1 is a lot of review, so we move pretty quickly, but I want some activities to go with it. The first one I made is here. If you are familiar with Everyday Math, you will recognize the number puzzles based on the 100s grid. Each puzzle has three parts: An answer key, the puzzle, and the number choices to use with the puzzles. I am going to laminate the puzzle into a file folder, and laminate the numbers. Students can work to complete the puzzle then check their answers. I have tried to make some different levels of puzzles to use.

Hope you can find a way to use this in your classroom. Thanks!
