Grade 7Mathematics

Focus: To begin grade 7, students extend their prior knowledge about geometry and geometric measurement. Doing this draws on abilities developed in earlier grades to identify, compose, and decompose shapes, as well as to extend their knowledge of length and area measurements. Students build on these abilities and their knowledge of geometry to study scaled copies of pictures and plane figures. They move on to apply this knowledge further to scale drawings, e.g. maps, scale figures/models, and floorplans. This unit specifically provides the learner with geometric preparation for later learning, for example, Grade 7 Unit 2 Introducing Proportional Relationships and Grade 8 Unit 2 Dilations and Similarity.

Throughout the unit, students discuss their mathematical ideas and respond to the ideas of others.

Number of Lessons: 13

Lesson Time: Approximately 45 minutes. Please note that each lesson is designed for one instructional block, and may be divided into shorter segments based on teacher pacing and student needs.
