This module focuses on comparing 2-D shapes and 3-D figures and sorting them by their geometric properties. Emphasis is also placed on identifying and describing the location and movement of objects on a grid map; exploring reflections, translations, and rotations; and investigating vertical, horizontal, and diagonal lines of symmetry.Also included: materials lists; activity descriptions; questioning techniques; problem-solving examples; activity centre and extension ideas; assessment suggestions; and activity sheets and visuals. All modules include a list of children's books and websites related to the mathematics topics introduced, a detailed introduction to the Hands-On Mathematics program (guiding principles, implementation guidelines, an overview of the skills that students use and develop during mathematics inquiry), and a classroom assessment plan and record-keeping templates.
