ActivePaperMath - The Jammed Board Triangle Similarity Challenge Silver
This geometry challenge poses three levels of problems. I typically assign the first level to all students with the other two as a challenge. The problem involves a board that becomes jammed in a box. The students enter their answers into the spreadsheet and the cell will turn green if correct. Level 1 (box width) is solved using similar triangles and the Pythagorean Theorem. It should be accessible to most students. Level 2 (jam height) starts out the same but leads into some fairly intense app

Problem of the Month - Petting Zoo Geometry
Problem of the Month: Through fun, quirky, challenging word problems, students will apply their knowledge of perimeter and area to help set up a petting zoo. Students will tackle a series of problems with increasing difficulty. The level A problems involve calculating area and perimeter of common shapes, and the level E problems involve maximizing area of a compound figure with constraints. This is designed for middle schoolers - sixth graders will be able to engage with the problems, and even e
