Geometry - Week 10 - Lesson 4 - Reflectional Symmetry
Objective (Teaching Point): Recognize whether a shape has reflection symmetry Know about the symmetry properties of triangles and quadrilaterals Lesson: Can review with this presentation on reflection symmetry. Have the students work on problems in the textbook on pages 250 and 251. When finished with the problems, try this worksheet. They will have to reflect across the mirror line (which we will talk about more next lesson). Support: Students having trouble seeing the lines of symmetry can cut out these various shapes and try folding them to find the lines of symmetry. Extension: Students who finish the class work can symmetrically color-in this rangoli design
