This time you need to cut out of colored paper circles of different sizes. Let the kid sows them as he laid out the squares and triangles, selects the largest and smallest. Then ask them to arrange the circles so as to obtain a pyramid (it probably already familiar with this toy). If it is difficult to determine which circle more, may impose on one another and in this way determines their "growth". Adhere the pyramid on paper
The remaining mugs put in an envelope.
