For both activities, students need to visualise the shape they are trying to make. You could help students by relating the shapes to their use in the environment, for example, a stop sign (octagon), a hazard sign (rhombus), and a road patrol sign (circle).
For this activity, students need to consider these features of a square: four equal sides and four right angles. (The comments for page 1 provide further details on the right angle.) Ask students, “Where are the right angles in a square?”
This activity is useful for introducing polygons. Poly means many and gon means angles. If a polygon is regular, all its angles are equal and all sides are equal.
Polygons that students might use include:
Polygons with sides and angles that are not equal are called irregular polygons.
