Grades 1 to 3 Geometry and Spatial Sense Every effort has been made in this publication to identify mathematics resources and tools (e.g., manipulatives) in generic terms. In cases where a particular product is used by teachers in schools across Ontario, that product is identified by its trade name, in the interests of clarity. Reference to particular products in no way implies an endorsement of those products by the Ministry of Education.

The expectations outlined in the curriculum documents describe the knowledge and skills that students are expected to acquire by the end of each grade. In Early Math Strategy: The Report of the Expert Panel on Early Math in Ontario (Expert Panel on Early Math, 2003), effective instruction is identified as critical to the successful learning of mathematical knowledge and skills, and the components of an effective program are described. As part of the process of implementing the panel’s vision of effective mathematics instruction for Ontario, A Guide to Effective Instruction in Mathematics, Grades 1 to 3 provides a framework for teach- ing mathematics. This framework includes specific strategies for developing an effective program and for creating a community of learners in which students’ mathematical thinking is nurtured. The strategies focus on the “big ideas” inherent in the expectations; on problem solving as the main context for mathematical activity; and on communication, especially student talk, as the conduit for shar- ing and developing mathematical thinking. The guide also provides strategies for assessment, the use of manipulatives, and home connections. 1 Purpose and Features of This Document This present document provides: • an overview of each of the big ideas in the Geometry and Spatial Sense strand; • three appendices (Appendices A–C), one for each of Grades 1 to 3, which provide learning activities that introduce, develop, or help to consolidate some aspect of each big idea; • an appendix (Appendix D) that lists the curriculum expectations in the Geometry and Spatial Sense strand under the big idea(s) to which they correspond. This clustering of expectations around each of the five big ideas allows teachers to concentrate their programming on the big ideas of the strand while remaining confident that the full range of curriculum expectations is being addressed; • a glossary that provides definitions of geometric terms used in this document. “Big Ideas” in the Curriculum for Grades 1 to 3 In developing a mathematics program, it is essential to concentrate on important mathematical concepts, or “big ideas”, and the knowledge and skills that go with those concepts. Programs that are organized around big ideas and focus on problem solving provide cohesive learning opportunities that allow students to explore concepts in depth. All learning, especially new learning, should be embedded in well-chosen contexts for learning – that is, contexts that are broad enough to allow students to investigate initial understandings, iden- tify and develop relevant supporting skills, and gain experience with varied and interesting applications of the new knowledge. Such rich contexts for learning open the door for students to see the “big ideas”, or key principles, of mathematics, such as pattern or relationship. This understanding of key principles will enable and encourage students to use mathematical reasoning throughout their lives. (Ontario Ministry of Education, 2005, p. 25) Students are better
