This is a 2-3 week maths project for anyone from Grade 3-6. Done in pairs or small groups the project entails students designing and building their own Lego house. In the project students will cover a range of maths concepts including area, perimeter, counting, money, graphing and interpreting data. The project includes a detailed teacher booklet with photographs of student's work and examples for each of the lessons. The student book is also included for students to work from, although we found sometimes it was easier to work out of a grid paper book for some concepts. I welcome any feedback on the project.
