About This Resource

This unit gives students a chance to take a closer look at traditional circle dwellings and complete a project wherein they apply an understanding of circles, polygons, and surface area to complete a diagram and scale model of a traditional circle dwelling. This unit can be used to help students achieve the following Prescribed Learning Outcomes for Mathematics 9: C1 solve problems and justify the solution strategy using circle properties, including the perpendicular from the centre of a circle to a chord bisects the chord, the measure of the central angle is equal to twice the measure of the inscribed angle subtended by the same arc, the inscribed angles subtended by the same arc are congruent, and a tangent to a circle is perpendicular to the radius at the point of tangency; C2 determine the surface area of composite 3-D objects to solve problems; C4 draw and interpret scale diagrams of 2-D shapes; C5 demonstrate an understanding of line and rotation symmetry.
