Big Ideas: Grade 4 

Draw and identify shapes, looking at the relationship between rays, lines and angles. Explore symmetry through folding activities

Problems (tasks which students do not already have the tools to solve) precede teaching of the focal mathematics necessitated by the problem.

That is, the major point of a problem is to raise questions that can be answered and encourage students to use their intuition to address the questions before learning new mathematical ideas (Deslauriers et al., 2019).

From the 2023 CA Framework

Draw a shape using 2 or more right angles that has:

• Just 1 line of symmetry
• At least 2 lines of symmetry
• 0 lines of symmetry
