The first part of the book goes through several simple examples explaining things like a factor tree, what prime and composite numbers are, and how the monsters help.
The next part of the book goes through each number 1 to 100, using those crazy monsters. This was of course, my daughter's favorite part. We actually went through the whole book in one sitting. She loved trying to figure out why that particular monster was used for his number. For instance, the monster to the right represents the prime number 2. Can you tell why?
Here is the prime number 7. Again, can you figure out why?
These first two are pretty easy, but they do get a little harder.
Now check out the composite number 14 below. Can you tell what two prime numbers are represented?
Some of the monsters can get pretty distorted. Below is the composite number 56. You can see on the left that the factor tree breaks the number 56 down to it's prime numbers. In the picture, you should be able to pick out three 2s and one 7. Can you?
My Thoughts: I think this is a great book, especially for the child who is a visual learner. It teaches a subject that is honestly, quite boring, and makes it fun and easy to learn. I think the best part about it is that the children are learning about prime numbers and they don't even realize it.
Thoughts of an 8-Year Old: The book is a good one. It tells about the number tree, which is like a family tree. The "Math Monsters" help with this. I drew the 1, 2, 3, and 5 monsters. They all have something in common about their numbers. For instance, on the number 1 Monster, it has one eye. The monsters are cute. Check out my drawing to the right.
