March 14 (3/14) is often referred to as Pi Day (3.14 in the math world). In the preschool class, the students learned a little about fractions on this day. No, Pi 3.14 is not a preschool concept but fractions can be to a certain point.
We used a large round circle with a big number 1 written on it. That was the pie. Then we cut a second round circle in half making 2 halves. We cut a third round circle into 1 half and 2 quarter pieces.
The students were able to put the pieces together on top of the big round whole circle to see that the 2 halves matched the whole and the 1 half and 2 quarters matched the whole as well.
