Draw and identify points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines; identify these in two-dimensional figures

Typical age: 9–10 years

“If your child is given a piece of paper and a ruler, can they draw a line segment, mark a point, and then draw another line through that point that runs perfectly parallel to the first?”
