Beginning in the
Fall, a group of eight kindergarten, first and second graders took part in a
math class focusing on Equalizing. Using a variety of manipulatives they investigated
how to make different lengths and weights equal. They decided to add on or take
away from two different lengths of string or chain links to make them equal.
Using wooden cubes and a balance they decided how many cubes to add on or take
away from the balance to equalize the balance. This investigating led the
students to create their own addition and subtraction number sentences.
