Session 4 — Quad Squad: Geometry Challenge

Opening concept: STEAM means the math and the engineering are the same problem.

Activity:

• Full Quad Squad lesson (from curriculum/AdditionalActivities/Quad-Squad-robots.pdf)
• Students program Edison to drive all four types of quadrilateral: square, rectangle, parallelogram, trapezoid
• Compare interior angles for each shape, calculate the exterior turn angle, program it, test it
• Debrief: which shape was hardest? Why? (Trapezoid — non-uniform turns)

Engineering connection: Understand before Build — write the turn angles down before programming them

Materials: Devices, USB cables, Quad Squad student sheets, protractors, rulers
