Multifixx is a toy and teaching aid at the same time. On a square base are 100 balls in ten rows of 10 balls arranged. The string is then wrapped around the balls, with the inside being the product of the two numbers. For example, if the string goes around the balls in row 6 and in column 4 and you bring the string back to the starting pointing, this is the product of 6 x 4 = 24, which are how many balls are in the enclosed area. Comes with a handy carrying case.
Multifixx is very simple and practical to use. It is especially suitable for children over 5 years in kindergarten and elementary school.
