I love to teach geometry because students must combine logic, visual perception, and math to solve problems. Why not add art and history into the mix as well?
Here is a challenging unit to reinforce basic understanding of calculating the area of complex figures. It will challenge the brightest students in your classroom!
We use vintage hotel and restaurant signs to solve problems about calculating the area of complex figures.
We begin with the basics and then ramp the level of challenge up and up and up—moving to multi-step problems and ending with an engaging and STEAMy model sign project. Along the way, you or your students can choose their appropriate level of challenge. Your younger GATE kids can get through all of it with teacher support, and your older students will hit an appropriate level of frustration . . . hopefully just enough to help them learn persistence.
My students are excellent at all sorts of calculations, but can they EXPLAIN processes of mathematical thinking as well? Can they use logical-mathematical thinking to make a plan about how to solve real-world sorts of math problems? In this unit, we challenge mathematical thinking and even (heaven forbid!) sometimes throw precision out the window (sort of).
You get ready-to-print activity sheets with sample answers, Common Core Math references, and pretty much everything you need to get going here. Start today!
