Learners classify lines, slopes and shapes. In this calculus lesson, students calculate the midpoint, segment and equation of a circle. They also review what a slope and angle of inclination is.

Students define slope, and practice finding the slope of lines through given points. They determine the angle of inclination. Students find the relationship between the slope and the tangent of the lines. Students determine special...

Students create tessellations. In this geometry instructional activity, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.
