Title
Exploring Perimeter and Area with Tile and Linear Pieces

Curriculum Source
Bridges, Grade 4, Unit One, Sessions 18-19

Pia Hansen Powell, Casper, WY

Contributor Notes
Casper K-8 math teachers participated in a professional development grant funded by the University of Wyoming. Teachers met in June of 2006 to experience algebraic thinking at multiple grade levels. This grant funded yearlong content coaching and monthly professional learning opportunities, powerful in creating a cohort of teacher leaders for the district. Here teachers are exploring area and perimeter concepts using colored tile and red linear pieces. Their dialogue and collegiality develops an understanding of best practice pedagogy and shores up content knowledge.

Contributor Notes
Fourth grade field tester Hannah Chandler sent me a collection of solutions her students wrote in response to a story problem about a quilt her sister was planning to make. Hannah made up the story problem herself and asked the students to follow their own class guidelines for solving problems. The solutions shown here illustrate a variety of strategies for solving double-digit multiplication problems, including repeated addition, the area model, ratio tables, and partial products. Hannah shared the ratio table strategy with her kids and it really caught on. I think it’s a really elegant way to solve multi-digit multiplication problems.
