Does your kid know what a quadrilateral shape is? If they do, this task might prove to be just a little too easy for them. However, if your kid does not know what a quadrilateral shape is, this worksheet will prove useful in educating them. First, explain to them that a quadrilateral is a shape that has four sides. For example, a square and a rectangle are quadrilaterals. Next, ask them to look at the pictures of shapes in the exercise and circle the quadrilaterals in the picture.
