Students use their knowledge of vertically opposite angles, adjacent angles on a straight line, and angles at a point to identify unknown angles in everyday shapes.
Students match descriptions of how many corners and sides 2-dimensional shapes have with their corresponding pictures and then describe one shape this way.
Students write short paragraphs using geometrical terms to describe two pictures. The terms equilateral, scalene, and isosceles are to be used to describe a castle. The words circumference, diameter, and radius are to be used to describe a bicycle.
Students calculate the size of marked angles using their knowledge of angle properties: the angle between a tangent and a radius, the sum of angles in a triangle and the sum of angles in a quadrilateral.
For this NEMP task students calculate the amount of pipe length and the minimum number of corners needed to make a cube-shaped frame with 1 metre edges.
