Are your Geometry students still struggling to remember the distance formula? I have used this strategy for years and my students have had great success. Students will turn the distance formula into drawing a picture.
This strategy takes the difficulty out of setting up the distance formula for students. When students are successful with setting up the distance formula then teachers can concentrate on checking for mathematical errors and making connections to the Pythagorean Theorem and to the equation of circles as the year goes on.
