These are the days where I dump the lesson plans and bust out an activity that gets us out of our seats and moving. In a pinch, I borrowed some fabric (and a fun activity) from my teaching partner. While sitting around our meeting area carpet, I had each student grab a handful of colored tiles and dump them on a large piece of fabric.
Looking at all the colorful tiles, I had my students turn-and-talk and estimate how many tiles we had on the sheet. I then had my kiddos discuss how we should sort the tiles to make them easy to count. We discussed how counting the tiles in groups of ten would make them much easier to count than counting them one-by-one.
I then took three other pieces of fabric and and labeled them with hundreds, tens, and ones. My kiddos stacked their tiles in groups of ten and placed each pile on the ones column.
They quickly noticed that we could easily regroup each set of ten and move them to the tens column. When we counted 10-tens, it was fun seeing their faces light-up and the excitement to tell me that it was time to regroup these tens to the hundreds column.
We kept this activity going until we ran out of groups of tens to move to the tens column or the hundreds column. After all of that regrouping, we ended up with one tile left over. As a class, we decided the best place for that tile to go was in the ones column. I was glad there was at least one tile left over for the ones column!
We ended up sorting 311 tiles in all! When all was said and done, we turned back to our original partners and talked about how far off our estimates were. Some students were pretty close to the actual amount... and they were very excited to tell me so!
Because of my knee, I decided to keep this activity indoors. But, my teaching partner did this activity outside with objects her students found in nature. How cool is that!?! When I'm feeling better, I'll be taking my students on a nature hunt so we can sort and regroup their findings.
How do you practice regrouping in your classroom?
I'd love to hear some new ideas to try! Regrouping is hard stuff!
