This chain can be used for 100 Day or any other time you'd like to practice skip counting to 100 by 10's.

Another activity you could do along with this, is to make 10 paper chains out of 10 different colored strips of construction paper. Suspend the chain from the ceiling or use as a border for a quick and easy way to count by 10's each day.

If you feel this is too long, simply run the 10-piece chain link off on 10 different colors of construction paper, cut and link only 10 paperchains.  Each one counts as 10, because there are 10 links on it.
