Ms. Montgomery’s third grade Title I math students at Holy Cross are learning about perimeters. As a group activity, they worked on estimating the perimeter. The objective was to guess the perimeter of a desk.

We estimated the length and width, then they drew their figures on the table to see how close they came to the correct size.

The third graders practiced problem solving by

  • estimating,
  • drawing and
  • checking their answers.

Estimating the perimeter, drawing and checking their answers was a cooperative effort!
