Geometry proofs can be extra challenging for students. Even parents remember solving proofs when they were in school. Paragraph proofs and two column proofs can be simplified by making them visual with a flowchart proof.
Students in Mrs. Petersen’s geometry class assembled their knowledge of congruent angles (vertical, alternate interior, angle bisector) and congruent segments (midpoint, isosceles triangle, reflexive, parallelogram) to prove triangles are congruent. All the needed information was given for students to cut and paste in the right order. Then arrows can show the flow through the process.
Although still challenging, students worked hard and found success. At the end of class Mrs. Petersen said, “I can hear your brains getting exhausted.” It is rewarding to see the skills of the first month of school assembled in to one problem. One of the students in class replied, “I think I actually understand flowcharts! It was easier than I expected.”
With all of the cutting and pasting, students saved paper by recycling (better known as reusing) old softball game programs.
See pictures below for examples of their work.
