Instructional Ideas

  • For Levels A and B, provide manipulatives, such as triangle tiles or cutouts

Classroom Considerations

  • Preview problems to see which level would be best for each learner
  • For Levels D and E, pupils must have knowledge of convex and concave quadrilaterals, as well as hexagons

Pros

  • Includes printable worksheets with triangle cutouts
  • Provides diagrams to make problems clear

Cons

  • Lacks answers to easily check students' work
