The lesson begins with a challenge to complete a specific course using a Sphero Spark Plus robot. Spheros were selected for this activity since they provide students with highly engaging opportunities to engaging in productive struggle to master mathematical concepts (Wheeler, Smith & Gardner ,2020). Through questioning, students review properties of right triangles, the Pythagorean Theorem, and protractor use before strategically block-coding a path through the course. Students were given a traced practice course, but the final test was to take their Sphero to the “official track” which had bumpers. Will their code be accurate enough to successfully navigate the course?
