EDU330 Algebraic Thinking

We solve two problems today - investigating polygons made on geoboard and arranging five consecutive numbers in a certain arrangement.

I recall doing this lesson with a group of gifted students in The Netherlands.

I particularly enjoyed students' attempt at finding the area of their polygons. In this photograph, two boys were quite animated in trying to calculate the area of the triangle.
