I understand CCs as a way to see how your students are thinking about numbers and how they use counting. I keep these questions in mind as I work with and listen to students with their CCs:

Does this student have 1-1 correspondence?

Is he/she subitizing? To what degree?

Is he/she organizing this collection in some way? How?

Are there consistent mistakes that this student is making in his/her counting?

In order for CCs to be the most effective, they should be used during a time when a teacher or another adult can sit with and talk to the students as they count. You can learn so many things about a student's numeracy skills during the brief period you spend with each of them and their CC. Here's a glimpse of some of my students using CCs yesterday with a brief description of what I learned about each of them:

This student began counting using 1-1 correspondence, but as he continued to the second row, he began to skip some cubes and was ultimately unable to tell me how many he had in his CC.

This student used 1-1 correspondence with the tiles, but he was not able to count past the teens. He became silent after 14 and just touched the tiles one by one until he got to the end.

This student organized his collection by the shape (and subsequently, color) of the beads. He was able to tell me how many were in his collection by using the number that the last bead was on top of.

This student focused on putting the letters in order rather than counting them. He spent most of his time trying to order the ABCs, and when I asked him to count he just continued looking for the 'H'. Lesson learned for using this CC!

This student had an assortment of counting bears and other small animals. He began sorting by size and color, then just size. He was using 1-1 correspondence but was not able to count past the teens.

These are just some of the CCs that were going on in our classroom at one time. Our instructional aid was also checking in with students. All of the information we learned came from sitting with each student for about 1 minute, tops. This time could be longer if the collections were bigger, but most of the collections I provided had 50 or fewer items. Now that I have this information, I will be able to provide more targeted instruction in small groups based on skills.

For now, we will probably do Counting Collections once a week. It is an excellent way to quickly gather a lot of information, and the best part is that the students think it's fun!
