For example
The posts of a fence are vertical, the rails are not.
In Grade 3
Children compare vertical lines with things that stand upright, like a post or a door frame.
Watch out for
Children often think a slanting line counts as vertical. A vertical line goes straight up and down with no lean.
Say it at home
Ask your child to find something vertical in the room and check it against a wall.
