I have really had math on the brain lately! And I have found some great math books recently that I have incorporated into our Guided Reading time (this book is a level N). The one I want to share with you is called Spaghetti and Meatballs for All! by Marilyn Burns.
It is a great book about a couple having their family and friends over for a spaghetti dinner. They carefully plan how many tables and chairs they will need, but things go awry when their guests start pushing the tables together.
We've had great discussions about geometry and standard units while improving our reading skills. My students were engaged by the story, and eager to share their mathematical ideas about how to solve the problems that the characters in the story encountered each time the tables were rearranged.
