Math Games: Variables
- Greater or Less?
Research shows that children as young as 5 are able to use statements like "A > B" to convey information about the relative lengths of 2 objects. This seemingly trivial accomplishment opens the door to an astonishingly powerful system of genuine mathematics; one that includes logic, proof, and symbolic manipulation, all without the introduction of a single numeral.
The Greater or Less activity has 5 levels of play. Each level is more abstract, and requires more logical analysis than the one before it. You can read more about this game by clicking the greater than/less than menu item.
