How the skills build
Lines and angle types come first. Classifying triangles by angle and counting pairs of parallel sides use those ideas on shapes, and the two symmetry skills finish the sequence.
Using these worksheets
- Review
Print one angle sheet and one symmetry sheet side by side after a unit, then ask children to hunt for the same ideas in the classroom.
