Teaching Lines and Angles
What it is
Naming lines, rays, segments and angles, measuring an angle with a protractor, drawing one to a size, and finding whether a shape has a line of symmetry.
When a child is ready
Use it once a ruler is handled steadily and right angles are recognized.
If they struggle
For the protractor, line the center on the corner and one arm on zero every time; most wrong readings are the wrong scale. For symmetry, fold a paper copy of the shape.
