Counting Project

As part of math workshop this September our class has been doing lots and lots of counting. We made a long list of all the things we could count in our classroom and started counting them and recording our results in pairs. We did lots of great math thinking as the children discovered that counting large quantities by 1 could take a very long time and could get very frustrating if they lost count! Pairs moved from counting by 1 to grouping items they counted and practicing counting by 5s and 10s. We had many great discussions about ways to count and record, how to keep track of our counting, how to check our answers, and how to work on counting with a partner. After many days of counting lots of different items both in our classroom and out on the playground we decided that we were going to try counting all of our unifix cubes as a class (and we have Lots of them!). This project took us several days but we learned a lot! We used ziploc bags to make groups of 10 cubes, then decided to put groups of 10 ziploc bags into plastic grocery bags (to make groups of 100 cubes). The class did a fantastic job of working together, grouping, bagging, and checking their answers until we were ready to do a final count. We ended up with 17 grocery bags of 100, 4 ziploc bags of 10, and 1 extra unifix cubes giving us a grand total of 1,741 unifix cubes! The class was very excited when we reached our final answer. Here are some photos of our process!
