Today I’m sharing a free prime numbers poster to download.
I have so many ideas of how I would teach things/do things if life was ideal. And, by ideal, I mean I could pause time occasionally and get 100% caught up with my to do list.
I’m pretty sure I have no idea what it feels like to be caught up with one’s list of things to do. I still have things on my to do list that I put on there when I moved to Drumright in July of 2012.
It’s now October of 2014. I guess subscribing to the local newspaper isn’t at the top of my list of priorities…
When I teach simplifying radicals, I teach my students to find the prime factorization of their radicand first.
Prime factorization is something that they should come to my classroom knowing, but I’ve found that many of my students need a short refresher course on prime and composite numbers.
I usually accomplish this by having my students classify the numbers between 1 and 100 as prime, composite, or neither. We make a little chart to keep in our interactive notebooks.
When students are working on finding the prime factorization, I encourage them to keep their notebooks out and open to this page. However, you know how that goes.
Students soon get where they just start assuming that a random number is prime instead of checking their chart.
Three years ago, I had this idea that I was going to make prime numbers poster to hang on the wall. It never happened. I taught radicals again. And, again, I vowed to make posters.
Silly me didn’t think to specify to students how to orient their papers before writing on them. Oops…
This year, I decided I was going to make this prime number poster thing happen. But, I had a sort of dilemma. The walls of my classroom are literally covered in posters. Where could I hang the prime numbers?
Eventually, I decided that I had yet to utilize a small 4 inch gap between the bulletin board and the edge of the wall.
I made a quick template in Microsoft Publisher that was 3 inches wide. It didn’t take long to duplicate the page and type in the prime numbers in a cute font. This was made and printed in 7 minutes tops.
The verdict? Success. Students are actually using the poster while working on their assignments or quizzes! And, this makes this math teacher oh so happy.
