The Robertson Program

Area and Perimeter

Graph papers overlapping with a title that reads, "Area and Perimeter".

Students use the sum of two dice to create the perimeter and area of shapes on a grid.

Perimeter Challenge

Two shapes made of blocks. A title reads, "Perimeter Challenge".

Students use square tiles to create various shapes and compare their perimeter lengths.

Pumpkin Math: Part 1

A student measuring a pumpkin with a measuring tape. A title reads, "Pumpkin Math".

A 2-part lesson exploring the relationship between a pumpkin's circumference, height, and weight.

Simulating Resource Sharing

A dock with yellow metal cages, ropes, and buoys, with a body of water and buildings in the background.

This lesson explores what happens when individuals act only in their best interests to get the greatest number of fish. The simulation will allow students to see the different possibilities of working together to conserve resources.

Spatializing Area

Two pieces of paper with blue and grey squares over top. A title reads, "Spatializing Area".

Students use cutout shapes to understand the relationship between size, area and relevant measurements.

Sum of Interior Angles of a Polygon

Three different math tools showing angles. A title reads, "Sum of Interior Angles of a Polygon".

In this lesson, students will explore the relationship between the sums of interior angles in different polygons.

Using maps and investigating catch rates to understand lobster abundance in Nova Scotia waters

A red lobster on top of a blue wooden lobster trap, surrounded by green vegetation.

Once students better understand the species, they can explore the interaction between lobsters and fishers.

Volume and Displacement of Water

Four plastic containers stacked. A title reads, "Volume and Displacement of Water".

Students explore displacement in large volumes of water by experimenting on a smaller scale.
