Student Work from Shapes and Designs, Problem 2.3

  View Student Work


A CMP teacher shared photos of students working during the Explore of the lesson. Students were testing to see which regular polygons tessellate. They were recording their results on chart paper Using the results, the students and teacher discussed how angle measures in the polygons can explain the tiling properties.

  • Students in the photos were exploring these questions from the teacher:
  • Which regular polygons will tile a flat surface with no gaps or overlaps?
  • Which polygons will not do so?
  • Why do some shapes tile and others do not?


The student work photos provide a glimpse into the CMP classroom during the Explore phase of the lesson. In particular, the photos show the active role of the student in the process constructing their knowledge around well-defined challenges.
