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.

I would definitely use this book as a teacher in my classroom to introduce and get students interested in the concept of subtraction.
