I post two photos a week on our little Moodle install and ask my students to submit five sentences on five concepts we discussed during the week.

Have them fold their notepaper into sixths.

Last year didn’t care about the sequencing. Parallelogram is a trapezoid on crack. A rhombus is a kite on steroids. Rhombus + Rectangle = Square. What do you notice about these three?

The point being that it doesn’t matter what it LOOKS like. Only what it’s marked up as.

Draw and define.
