Proof with Parallelogram Vertices
Geometric figures are perfect to use for proofs. Scholars prove conjectures about whether given points lie on a triangle and about midpoints. They use a provided dialogue among fictional students to frame their responses.
Curated OER
Dilations with Matrices
Examine dilation with matrices with your class. Learners write a conjecture for how the scale factor determines the size of an image. They then use their conjecture to write a matrix multiplication problem for the illustrated...

Four Color Theorem
Students identify and interpret how the Free Response questions are graded on an AP Exam. They also discuss coloring the included map, placing several examples on the board to determine the number of colors necessary to color each....
Curated OER
Cooperative Conjectures
Students compare and contrast how animals have coexisted with humans. They also identify industrial changes and how animals were affected. They use the internet to research information and present their findings to the class.
Curated OER
Glaciers
Seventh graders summarize how Earth processes today are similar to
those that occurred in the past. They read excerpts from John Muir's "Yosemite Glaciers" and explain how slow geologic processes have large cumulative effects over long...
