In this activity, look carefully at each object shown on the screen and identify its 2D shape. Think about the shape by counting the number of sides and corners, or by checking if it is round. Then click on the object and select the correct shape that matches it to make a pair. Work quickly and carefully, as you have 30 seconds to complete each match. You are allowed to make two mistakes, so think before you choose your answer. If you make a mistake, try again and choose the correct shape. Continue matching all the objects with their correct 2D shapes until the activity is complete.
