In this 2-week unit, students are provided opportunities to:
- identify angles as measures of turn and compare angles to a right angle (Stage 2)
- compare and describe the features of two-dimensional shapes (Stage 2)
- represent and read analog time (Stage 2)
- classify two-dimensional shapes and describe their properties (Stage 3)
- estimate angles and use a protractor to measure, identify and compare angles using degrees (Stage 3)
- solve problems involving duration, using 12- and 24-hour time. (Stage 3).
