Start by making the shoe box and the cardboard discs. Cut a narrow slit on one side of the shoe box top and a small circle on the other side. The narrow slit will be used to insert the discs and the small circle will be used to insert the clothespins.
On the cardboard, draw 10 or more circles, about 3 inches in size. Cut out the circles and attach a clothespin to each circle.
Have the child separate the clothespins from the discs and insert the items through the right opening on the shoe box.
You can also place stickers on the circles and matching ones on the clothespins. After the child inserted the items, ask him to take them out of the shoe box and match each circle with the corresponding clothespin. You can also color the circles and the clothespins in different colors, and ask the child to match the items by color.
