Crazy Socks Skip Counting Clothesline

Each year I ask the kids to bring in a pair of socks and we build a counting by 2's clothesline. I write the odd and even numbers in two different colors, put a dot below the multiples of 5 and circle, a star above the multiples of 10 and I circle the multiples of 2. This year, I asked the kids to bring in crazy socks which made the activity more fun and colorful. I also extended the use of this number line by using Post-It notes to cover some of the numbers and having the students tell what numbers were covered. Note - I used yarn and clothespins, but had to staple the yarn in several places to keep it from stretching and sagging. :)

For a little added fun to practice skip counting, we read Hands Down by Michael Dahl and labeled the reindeer antlers in a skip counting by 5's pattern, 0 - 95. I always begin with zero to give the kids a frame of reference for the beginning of every skip counting pattern.
