Casting Nines
A Quick Check for Math Computation

Help students eliminate careless mistakes from their math papers with a simple method of checking that works with addition, subtraction, multiplication and division. Most students view casting nines as a game or puzzle, and check their work more carefully than ever before. This reproducible book will enable you to learn to cast nines right along with your students!

The Casting Nines book has been excellent for the students. They are so happy to know when they are right when multiplying is done. I feel like I taught multiplying for 30 years in the dark without the casting nines method.
