This is a great lesson to use to review how to identify an even and odd number and how to identify place value. My students loved getting to know their classroom number today!
Begin by thoroughly going over the details of the project. Teach the students how to curl cardboard (cereal boxes) by wrapping a strip around their finger tightly. This technique will help students with "curvy" numbers. Teach the students how to create multiple L-Braces with cardboard strips and tape by lining up a 4 cardboard strips vertically, connecting them each with a strip of tape, and wrapping them to create a rectangular prism. This technique will help students with "straight" numbers.
Students glued their design brief into their STEM journals and made 4 corners on the page next door. In boxes 1 and 2 students created two plans. They had to think about how they would build their number, their base, and how they would incorporate their tasty treat. Once they had two plans they were allowed to begin building. When students were finished building they reflected on their design. In box 3 students wrote one problem that they encountered and in box 4 they wrote how they solved their problem.
I was so impressed by the problem-solving and thinking that my students put into this project; never underestimate the creativity of a 7 year old!
