The Mole as a Large Number or an Exercise in Dimensional Analysis
Students complete an activity and make "provable estimates." In this dimensional analysis lesson students use dimensional analysis and complete an activity.
Curated OER
Shapes Around Us
Students identify basic two-dimensional shapes. They are able to identify the four basic two-dimensional shapes: squares, rectangles, triangles, and circles. Students write/draw in their learning logs a reflection of what they noticed...

Finding Polygons in Cubist Art
Fourth graders explore geometric properties and relationships in a two-dimensional work of art. They first search for and identify polygons in a Cubist painting and then use polygons to create their own Cubist portrait of a classmate.
Curated OER
A GREAT SPORT
Students explore how diverse groups and individuals have contributed to the cultural development of Canada, and then produce two-dimensional works of art.

Straws and Shapes
Students investigate the concepts related to observing two dimensional objects. They also build three dimensional objects using the two dimensional objects. The students give an oral or written explanation for how the pieces fit together...
Curated OER
Shape & Form
Students analyze the difference between shape and form. They identify, explain and use the basic elements of design and determine that forms are three-dimensional and shapes are two-dimensional. They sketch it on their paper and then...
