I am interning in first grade, and I am having trouble teaching the concept of subtraction. I do not want to simply drill students into memorizing subtraction facts.

This book is another good book from the author. It shows different scenarios to match the subtraction problems that come with the book. The colorful illustrations make it very easy and engaging for students. There is also a really great "extra" activity page at the end that would be a great way to extend learning. I would definitely use this book as a teacher in my classroom to introduce and get students interested in the concept of subtraction.

This book is good for a math lesson on subtraction. It has examples of subtraction problems, using the traditional algorithm and also the horizontal method. Mainly subtracts single digit numbers. It creates simple word problems and equations it has a glossary of terms in the back and also has helpful web sites to future explore. Can be used as a workstation or as an introduction to odd numbers.
