6 This guide provides teachers with practical applications of the principles and theories that are elaborated in A Guide to Effective Instruction in Mathematics, Kindergarten to grade 6, guide provides: an overview of each of the three big ideas , or major mathematical themes, in the Geometry and Spatial Sense strand. The overview stresses the importance of focusing on the big ideas in mathematical instruction to achieve the goal of helping students gain a deeper understanding of the mathematical concepts; three sections that focus on the important curriculum topics of two-dimensional shapes, three-dimensional figures, and location and movement.

7 Each of these sections provides a discussion of mathematical models and instructional strategies that have proved effective in helping students understand the mathematical concepts related to the topics; sample learning activities for Grades 4, 5, and 6. These learning activities illustrate how a learning activity can be designed to: focus on an important curriculum topic; involve students in applying the seven mathematical processes described in the mathematics curriculum document and reproduced on pages 10 11 of this document; develop understanding of the big ideas in Geometry and Spatial guide also contains a list of the references cited throughout the guide.

8 At the end of the guide is an appendix that discusses assessment strategies for teachers. There is also a glossary that includes mathematical and pedagogical terms used throughout the towards Equitable outcomes for diverse StudentsAll students, whatever their socio-economic, ethnocultural, or linguistic background, must have opportunities to learn and to grow, both cognitively and socially. When students can Geometry and Spatial Sense, Grades 4 to 66make personal connections to their learning, and when they feel secure in their learning environment, their true capacity will be realized in their achievement.

9 A commitment to equity and inclusive instruction in Ontario classrooms is therefore critical to enabling all students to succeed in school and, consequently, to become productive and contributing members of create effective conditions for learning, teachers must take care to avoid all forms of bias and stereotyping in resources and learning activities, which can quickly alienate students and limit their learning. Teachers should be aware of the need to provide a variety of experiences and to encourage multiple perspectives, so that the diversity of the class is recognized and all students feel respected and valued.

10 Learning activities and resources for teaching mathematics should be inclusive, providing examples and illustrations and using approaches that recognize the range of experiences of students with diverse backgrounds, knowledge, skills, interests, and learning following are some strategies for creating a learning environment that acknowledges and values the diversity of students and enables them to participate fully in the learning experience: providing mathematics problems with situations and contexts that are meaningful to all students ( , problems that reflect students interests, home-life experiences, and cultural backgrounds and that arouse their curiosity and spirit of enquiry); using mathematics examples drawn from diverse cultures, including those of Aboriginal peoples; using children s literature that reflects various cultures and customs as a source of math-ematical examples and situations.
