Okay, I'm having trouble finding different ways to say "composing and decomposing numbers" in my post titles! But seriously, it's just THAT important, so I keep writing about it. Our Kinders and Firsties should be doing these types of activities extensively, so it's important to find lots of different ways to approach the skill. Today I present Clothespin Count. Students use strips that have dots showing 5 (pictured below) through 10. Choose the number that your kiddos need to work on. They don't all need to be working on 5; that's how you differentiate this activity. You'll need two different colors of clothespins, and you need as many of each color as there are dots on the card. So, if kids are working on 5, they need 5 of one color and 5 of the other. Students use a random number generator (several options shown below) and put that many of one color of clothespin on their strip. Then they complete the number with the other color of clothespin. Place a Math Talk card in the workstation that says, "____ and ____ make ____" so they use the correct mathematical language to describe the combination they have made. So in the first picture shown, the student would say "1 and 4 make 5." They draw another card (or roll the number cube again) and make another combination.

|Using a number card for the random number generator adds an abstract (symbolic) component to the activity. Now you have concrete (clothespins), representational (the dots), and abstract (the numeral).|
|Another option for the random number generator--a card with ten frames or actual ten frames.|
|This shows how students can show their work on the B & W version. As they progress, they could write the actual number sentence instead of using "and" and "make".|
|Copy and cut apart strips for workstations. Strips included for 5 through 10.|
