The Wonder Number Spinner
The various colors and shapes, and the terminology associated with them, are introduced to children through the use of the Wonder Number Spinner. In the beginning, children do not necessarily need to understand what factors, primes, and square roots are in order to play the various games. They just need to be able to match colors, circles, and squares. As your children become more proficient in the individual games, they will understand the definitions of factors, primes, and square numbers.
The Wonder Number Spinner is broken into twentyfour different sections whose colors and shapes correspond to those on the board (see fig 6). Each colorcoded factor from 2 to 10 has two sections. Square, Prime, and Odd each occupy two as well. The size of each section represents the probability of spinning that number, or type of number, based on how many blocks on the Wonder Number Board contain that information. For example, there are fifty blocks on the board that have a Blue 2 as a factor and only eleven that have 9 as a factor. So, there’s a much greater chance of spinning a 2 than a 9. Recognition of the fact that some numbers have a greater probability to spin has important strategic implications when playing various games.
