Barnhart School Second Graders Playing the “Exchange Game”



Barnhart School 2nd graders are playing the “the exchange game” and developing place value concepts in math. For school children to understand place value, they need to first be able to name small numbers, do simple additions and subtractions with small numbers, and understand about groups in counting (or skip-counting). If you have lots and lots of objects, the efficient way is to count them in groups, not individually.

A key indicator of the extent to which students have developed a sound basis for place-value is the extent to which they can efficiently count large collections and confidently make, name, record, compare, order, sequence, count forwards and backwards in place-value parts, and rename 2 and 3 digit numbers in terms of their parts.
