Can you make a square meter that’s not a square?

We did!

Last week, we enjoyed an investigation into area and perimeter. We were challenged to make two shapes with the same area of exactly 1 square meter but different perimeters. All our shapes looked different: triangles, hexagons, octagons and even an icosagon (20-sided polygon)! In each case, when we changed the form of the shape, the perimeter increased.

At the end of the task, we recorded our understanding in a mathematical reflection. Take a look at Kazuki’s excellent explanation of the task below.

Great mathematical thinking, Grade 4! It is wonderful to see you talking to each other, asking questions, checking measurements and solving problems!
