Big Ideas:
A two-dimensional shape has a line of symmetry if it can be folded along a line into matching parts.
This lesson builds on students' knowledge of line symmetry. The task asks students create a symmetrical figure with pattern blocks that follows given criteria. Through exploration of the shapes, students will see that patterns and designs can be created using lines of symmetry. Their work in creating a symmetrical figure leads them to see that shapes may be oriented differently across a line of symmetry.
Vocabulary: line of symmetry, symmetrical figure, symmetry
Special Materials:
