The book I chose, I will actually be using in class tomorrow. I am talking about benchmark numbers and this books gives great examples using items that we very rarely ever count out, like rice or Cheerios. The book will show one page of 100 pieces of rice and then school a page and ask the readers to estimate how many pieces are on a full page. I do have some kids who want to try and count, but they tend to loose patience after a few minutes. This books gives students real like items to estimate.
Check out all of the other great books people write about and maybe link up one of your own Mentor Texts!
