For the number recognition, I wrote the numeral on the CD. On the clothespin, I wrote the numeral, the written word and corresponding dots.
The color CD I used office dots. Some I had to create by coloring with marker. Write the color word in colored marker on the clothespin. The children really love this simple homemade activity.
This activity could also be adapted for older children-contractions, antonyms, math facts, state capitals and much more. The possibilities are only limited to your imagination.
