I decided to create handouts for warm ups for one of my second semester classes. I wanted to formalize some of what I already do to help strengthen their number sense. I plan on doing counting circles which my students really seem to dislike(!). Nevertheless, I think there is great value in doing counting circles, both in terms of the skills and the culture it helps develop in the classroom. We will also be doing more Estimation 180, Visual Patterns, Would you Rather along with balance benders, Daily Desmos, Always-Sometimes-Never and math talks. I created the handout and have filled in the warm ups for the first 5 weeks. They look like this:
There will be 18 weeks worth within the next few days (let me know if you want them - I'm happy to share). I then plan on copying them for each student and putting them in a duo-tang which will not leave the classroom. With the possibility of 24 students in that class, that makes 432 copies. We are repeatedly told not to make any unnecessary copies at school so I began thinking that it might be simpler to send my warm ups to Staples for copying. I looked at Staples prices and this is what I found:
Hmmm. The cost for 432 copies would be $34.56. But the cost for 500 copies would be $30. I see a nice (real-world!) math problem here.
