This is not a full math program, but a supplement for families wanting to work on math facts.
Addition the Fun Way: Elementary, Storybook format, Workbook, Audio (storybook on tape, great for in the car). No manipulatives, basically each number is a character in the story so I guess they are the manipulatives, LOL.
Style of materials: The storybook, very colorful, each chapter is for a number, 1, 2, 3's, 4's etc., Each chapter either has a rule or trick or a story that the child reads. By remembering the story and the picture he remembers the rule/fact. The cool thing is after the addition facts have been memorized you remove a character from each story to do subtraction!
Multiplication the Fun Way: Same format except the CD is Music songs for each fact (different than the storybook) also there is a magnetic storyboard with all the characters available as well. Great for the fridge too.
