Students identify the viewpoint from which an isometric drawing of a plan of blocks has been drawn and then make their own isometric drawing from a different viewpoint.
Students use the angle between a tangent and a radius property and the base angles in an isosceles triangle property to find an unknown angle and to explain why line segments are of equal size.
Students use their knowledge of the interior angles of regular polygons, isosceles triangles, and parallelograms to work out unknown angles for a variety of 2-dimensional shapes.
Students complete a table showing the number of matchsticks used in a spatial pattern, identify the number of matchsticks required for a given shape, and describe the rule for the pattern.
Students are provided with a diagram of a bag used in solar showers. They answer questions about this bag relating to heat absorption, heat transfer, and radiation.
