The ETC Place Value Game

Have you noticed the difficulties that your children have been having placing the tiles correctly on the decimal checkerboard? The reason for this is because the entire idea of multiplication between decimals results in a product that is smaller than what they started off with. This is counterintuitive to the fact that up until now they have become accustomed to the expectation that every time, they multiply by two numbers the results are much larger numbers. This work, in the form of a game, helps the children reinforce the idea that decimals originate and fan out from the unit. Acting as a bridge between the decimal fraction board and the decimal checkerboard, it lays the foundation for cementing whole numbers and decimal place value. Not only does it assist children in placement of tiles on the decimal checkerboard, but it indirectly exemplifies the numerical prefixes showing the place value moving to infinity.
