The development of number sense includes such concepts as counting. Rote counting is the first step but children need to realize that as they count, the amount is increasing. Conservation of number is another important concept. The number of bears is still six, even if they are spaced farther apart.
We experimented with different arrangements of six counters. We placed them in a square shape, in a straight line, and in different combinations (3 and 3, 4 and 2, 5 and 1) which will help us to better understand when we begin adding numbers.
