A side is a straight line used to form a shape, just as pictured in the worksheet. An angle, on the other hand, is formed at the point where two sides meet, as also pictured in the exercise. Before going into this exercise, you must first make sure that your children fully understand what you have just explained. Then, help them complete the tasks in this printout. Check the birds that are holding shapes by their angles in the first exercise. In the second exercise, your kids must check the birds that are holding shapes by their sides.
