My eight year old daughter has a learning disability that really shows up in math. When learning a simple addition or subtraction fact, she’d perfect, and then forget. After flashcards, software, other workbooks, tutoring, manipulatives and summer school, I decided to try Two Plus Two is Not Five.  I can see now that she “gets it.” She can recall the trick when she sees the numbers. She is so excited about being successful and absolutely loves math. The book may anchor my daughter’s academic future. Thank you.

I just bought the book Five Times Five Is Not Ten from Mardel's, and love the strategies to teach multiplication.  The hands on activities, along with strategies will help my students to really "see" and know their facts, not just skip counting to get to the next multiplication facts.  I like the book so much I'm ordering the Two Plus Two Is Not Five to see how to help 1st and 2nd grade with their addition and subtraction.  It's obvious a lot of research has gone into these books.

Two Plus Two Is Not Five: This is an awesome book. I bought the book the summer after my son’s kindergarten year. I wanted him to be able to add some of the smaller numbers without having to count on his fingers or draw stick figures. I switched some of the chapters around because he was grasping some concepts faster than others. When we got to the “trick” for Number in the Middle, I made a car game out of it, and began asking numbers in the middle as we were driving. Once he mastered that, I began using the practice worksheets. A huge success! I didn’t try to have my son master each “trick” in one sitting; we have paced his learning, and this summer we will be working on some other add and subtraction facts as well as moving into the multiplication book. I told all of my friends about the book, how it has enhanced my son’s ability to add and subtract with accuracy and speed as well as build his confidence in math. Lastly, his teacher told me that he was one of her brightest math students.

We have an on-going tutoring program as a part of our school supply store. I have been using your book, Two Plus Two Is Not Five, as the basis for my math students. It is everything I need. Students get the practice they need to keep skills fresh and, as a result, they are able to transfer these skills into the classroom.  Students feel such a sense of success.  Thanks for a great book.

Have received the multiplication one and look forward to implementing the strategies from both books this year. Thanks for coming up with such appropriate and useable materials.
