Here it is in action:
To help my students keep track of the number sentences they had created and ensure that they didn't make the same one twice, I created checklists for each number. As they created each number sentence, they found it on the checklist and crossed it off.
Double-sided red/yellow counters worked wonderfully with this concept. To make it simpler for my kids, I had them start with the counters all on the same color to record the number sentence. To make the next one, they were only allowed to flip over one counter at a time. This also was helpful to keep them on track for decomposing the numbers in different ways.
I shared these activities with my kinder team and they told me that I just HAD to post in on TPT - so I created a new little activity pack with all of the sheets you see here, plus more! I have included printable red/yellow counters for you to create your own if you do not have the plastic ones seen here. I also made the activity sheets on legal sized paper so the kids had plenty of room to show their work. Here is a preview of the "How Many Ways?" pack available in my store:
