Quadrilaterals

Several years of work are coming together nicely. Unfortunately, I still have tests to grade.

There are so many properties for students to know and remember in the quadrilaterals unit of Geometry. I started by creating flash cards on two sheets of paper back to back.

Students had to write the property based on the “quadrilateral hieroglyphics” displayed on the card. Some struggled with filling them out because even though I explained it and showed it, they did not get the fact that images are reversed when flipping a paper over to write a property. They also spent too much time simply copying information and not processing it. I did make a cool game board to go along with the flashcards so they were dual purpose and the game was used as our chapter review.

Last year I made some Vizual Notes to help students have the properties on two full sheets. That seemed to help, but my intention was to include notes on the back that matched my presentations. I didn’t fully sync that up until this evening.

The thing I’m most excited to use with my students, though, is a Geogebra app I created that hopefully will help them discover the properties on their own.

There’s a “notice and wonder” sheet to help them kick off the quadrilaterals unit as we explore the properties of parallelograms.

Now, to wake up and get out of the house early enough to print and make copies.
