In keeping with Everyday Math instruction, the kids were given the option to round their measurements to the nearest centimeter. This method was also applied when calculating the half measurements. For example, if the actual measurement was 35 cm, the half measurement would be 17 1/2 cm. The kids were given the option to use either 17 or 18 as the measurement.
I was thrilled with how completely engaged the kids were in this project. The Mini Me Second Graders look fabulous!
