I am 39 and have some learning disabilities. Positive and negative numbers have ALWAYS confused me. I felt like I understood adding and subtracting and then they changed the math universe on me when they introduced the concept. I am not someone who can just do math by rote, I have to understand WHY it works the way it does, and if I don't I just cannot retain the rote rules they wanted me to memorize. This book explains negative numbers in a way that I really get it for the first time in my life.

The book is written for children, and I think it would be wonderful for kids, I so wish I was taught the concept like this to begin with. They use manipulatives to cement the the concept, which it really useful for kids. It takes an abstract concept and brings it into the real world. Being an adult I didn't actually use the manipulatives, but the explanation about why they work was invaluable to me.

They use a comic book style to explain each new step, and start out really simply, but if you were taught the traditional way it is a shift in how to look at negative numbers. It blew my mind a little at first, but in a really good way! As an adult the comic book part is a bit weird at first, but it really is a great way to show what they want you to understand without the risk of confusing someone with paragraphs of text, this is true especially for kids, but since it was a major shift in the way I understood the numbers it was very helpful for me to see it illustrated and not just written out.

The problems are broken up into a set of manipulative work with a mat you can copy and use, if you need it, and then a set to just do on paper. When you switch to the paper work you are given a rule to help you remember how to handle the problem, which is helpful for retention.

I was having trouble explaining positive and negative numbers. This is a different approach to teaching that concept, and it worked for my son. Since that was the whole point. The hands on approach and the different way of describing -4-4 as "negative 4, negative 4" rather than -4 minus 4 made it click for him.

Enjoy pre-algebra with the positrons and negitrons. I got this to help my son learn pre-algebra. He really enjoyed the comic at the front of the book and wanted more. Unfortunately, there were no more.

The book opens with a cool comic about positrons and negitrons (positive and negative number creatures), and then is followed by some lessons and tips. There are 2 games at the end of the book.

Each magic tip has a lesson to go with it. The book outlines everything very carefully and moves at a slow pace. We skipped in some areas but some students might need more and it's there. My son wanted to do some lessons and get another comic but the book didn't work that way.

There are a couple games in the back of the book though. I didn't think they were anything special but my 8YO thought they were amusing.

This book does not ship from Amazon. Ours was shipped in a brown paper envelope which allowed the book to get all bent up. I had to put it under some heavy books for a few days to get the wrinkles out enough to use it. Try to get if from a local bookstore if you can.
