For example
Each point of a drawn star is a vertex of the shape.
In Grade 3
Children point at the corners of solids and flat shapes, using vertex as the proper word for them.
Watch out for
Children often use vertex for any point on a shape. A vertex is only where sides or edges actually meet.
Say it at home
Hold up a box and count its vertices, touching each corner as you go.
Younger children may meet this as: corner point.
