Today I want to share with you 3 different solutions to a three digit addition problem that I posed this week to a group of third graders who are a bit behind where they should be but are working hard to construct their own knowledge about addition.
|This idea is one I see many second and third graders try out. It works on every problem and is fairly efficient. They are adding numbers by place value and it is a strategy many students invent for themselves.|
I was surprised to learn a few weeks ago that another book by the same author existed that I did not know about. I saw this book on a colleagues shelf and knew I had to have it. It has a WEALTH of mini lessons for working on addition and subtraction and had I had this book a few years ago it would have made my journey to being a better math teacher much smoother!
What opportunities are you providing for your students' to develop their number sense?
