Semi-Circle Shapes Worksheet for Kids

How to use this worksheet

Begin by showing your child an example of a semi-circle, explaining that it's half of a circle with one straight edge and one curved edge. Look at the images on the worksheet together, asking your child to describe each shape before deciding if it matches a semi-circle. Have your child circle every object that is a semi-circle shape, skipping over full circles, squares, or other shapes shown on the page. Once finished, count the circled semi-circles together and review any shapes your child skipped to reinforce the distinction.
