5.0 out of 5 stars A must for math teachers!!!, August 12, 1998

By A Customer

This review is from: Arithmetricks: 50 Easy Ways to Add, Subtract, Multiply, and Divide Without a Calculator (Paperback)

I plan on using this book to enhance my students mental math abilities. This book is a great way to do the mental math and focus on that higher order thinking. This book is organized well, and is well-suited for classroom use. There were many tricks that I didn't even know existed and everything is still based on basic math. This can work from the slowest to the most advanced learner.

5.0 out of 5 stars She loves math now!, November 8, 2002

This review is from: Arithmetricks: 50 Easy Ways to Add, Subtract, Multiply, and Divide Without a Calculator (Paperback)

My 9 year old had always loved math but this year we moved and neither of us liked the math curriculum the new school used. She began hating math! We began homeschool (there were other problems too) BUT she continued fighting with the math work. I purchased this book and after only 4 lessons she's hooked on math again! She loves the tricks and VOLUNTARILY makes up her own problems to solve! She's already seeing how the "tricks" help her in her "normal" math work.

It is plainly a superb book, I'm amzaed that the mathematical tricks in this books are so useful in everyday life. It liberates one from growing dependency on calculators. It's a treat now to be able to do complex multiplication & division calculations in ones mind. Regular practise of tricks is a must for max benefits.
