Do you want an engaging summative assessment for your geometry unit? This project has your students designing a space using only quadrilaterals. They must use each of the following quadrilaterals: parallelogram, rectangle, square, rhombus, and trapezoid. Once they create the design, they have to make a key for it, consisting of each shape and its properties, along with symbols and labels for each of the parts of their design that would be categorized with each shape. **Digital version in Google
