Here is how I have it set up on our learning shelf at home. I found the little basket and wooden box at my favorite local thrift store. I seriously need to stay away from that place, but it draws me like a magnet.
Here you can see a better view of the cards. I am using the little wooden box to hold the clothespins.
To do this activity, the child counts the snowflakes on the card. Very good for practicing one-to-one correspondence.
Then they attach the clothespin over the number that represents the quantity. Great for strengthening finger muscles AND for practicing number recognition.
I had my cards laminated at a local teacher supply store. Then I used a permanent marker to make a dot on the back so the child can self-correct.
