For example
A Ludo dice has twelve edges and eight corners to count.
In Grade 3
Children run a finger along each edge of a box, counting where two faces meet.
Watch out for
Children often mix edges up with faces. A face is a flat surface, an edge is the line where two of them meet.
Say it at home
Hold a box and count the edges together, tracing each one with a finger.
