In this 2-week unit students are provided opportunities to:
- solve problems involving duration, using 12- and 24-hour time
- investigate angles on a straight line, angles at a point and the relationships formed by the intersection of straight lines
- dissect two-dimensional shapes and rearrange them using translations, reflections and rotations.
Geometric measure A – MAO-WM-01, MA3-GM-03
- Angles: Estimate, measure and compare angles using degrees
- Angles: Use a protractor to measure and identify types of angles
Geometric measure B – MAO-WM-01, MA3-GM-03
- Angles: Investigate angles on a straight line and angles at a point
- Angles: Investigate the relationships formed by the intersection of straight lines
Two-dimensional spatial structure B – MAO-WM-01, MA3-2DS-01
2D shapes: Dissect two-dimensional shapes and rearrange them using translations, reflections and rotations
Non-spatial measure B – MAO-WM-01, MA3-NSM-02
Time: Solve problems involving duration, using 12- and 24-hour time
