A 223 page paperback math workbook with answers in the back.  It is filled with comic book type space travellers who present and explain how to do math etc.  So much fun!

It starts with simple addition and subtraction and goes through multiplication and division.

It is published by Scholastic in  collaboration with Universtiy of Denver Mathematics Laboratory.

I will do a 2 for 1 for this book with any book I have posted.
