This lesson is based on the results of a performance task in which we realized that students' understanding of area and perimeter was mostly procedural. Therefore the purpose of this re-engagement lesson was to address student misconceptions and deepen student understanding of area and perimeter. The standards addressed in this lesson involve finding perimeter and area of various shapes, finding the perimeter when given a fixed area, and using a formula in a practical context. Challenges for our students included decoding the language in the problem and proving their thinking. (7th Grade Math)

This short video and interactive assessment activity is designed to teach second graders an overview of area.

This project is best completed prior to reading the novel, Mistasiniy:  Buffalo Rubbing Stone by Mary Harelkin Bishop to avoid influence of references in the text.  The original size of the Lake Diefenbaker mistasiniy is introduced in the novel's preface, while the size of the mistasiniy on Danny’s family’s land is mentioned on page 109 as part of Rose’s diary.   Students will work individually on a math inquiry problem challenging students to solve questions using estimation, approximations, geometry, analytical thinking, creative thinking, communication, and technology skills. Cross-curricular connections can be made with ELA, Social Studies, Science, and Arts Education. More information on bison/buffalo rubbing stones

Students will have to solve the real world problem of locker smell leakage by building an air filter that will cover the vents on the top of a locker. This project goes well with a curriculum on the particle nature of gases and phase changes.
