I have used guided math in my classroom for over ten years. I begin my teaching time block teaching/spiraling math concepts as a whole group, but most of my math block is devoted to guided practice in small groups followed by independent or small group practice, centers and intervention. I begin my math time every day with a page from my popular Number of the Day series. You may find more math in this “printable” format in my store.

I hope that you and your kids enjoy this fun resource. Check out my store for lots of fun math units including my popular Number of the Day units for grades K-Second.
