What to do during the last days of math class?

-
Image
Here is my criteria for what makes good mathy activities for the end of the school year: -no/low tech (we have 1:1 devices, but the last few days of school usually mean all devices are turned in) -still incorporate math or problem solving in some way -fun and engaging video credit:  http://sci-toys.com 1. My favorite activity is one I've done every year. Kaleidocycles . When I first starting doing them, over 10 years ago, I had to figure it out on my own. Now, there are tons of online tutorials (check youtube) to explain how to color, fold, and glue. You can also check out my blog post about making these . Kid love them, trust me. It's been my go-to activity for the last two days of math class for years for a reason! :) 2. 5x5 Game. Check out Sara's blog post about the rules . She calls it "the most amazing game" and I trust her judgement. :) I haven't tried it yet, but I'm leaving it as sub plans for the last days of school becau...

If you teach middle school, brace yourself for the craziness that is Valentine's Day celebrated at school tomorrow! Heart shaped suckers, teddy bears, chocolate, and a few (hopefully minimal) tears. Instead of fighting it, embrace the mathiness that can be squeezed out of this heart-filled holiday! Here are a few resources to use: 1. Send a Math-o-Gram . Love math? Love Desmos? You can send your students (or friends) a heart themed graph! 2. Make a Mathy Valentine Use transformations to rotate your way to your students' hearts. 3. Check out these other heart-shaped graphing activities I found these NCTM Illuuminations graphing actives a few years ago. 4. Graph this equation in Desmos : (this was a fun one for my 6th graders... just to figure out how to type in the correct symbols!) 5. Mobius Strip Hearts ?! Yes! Happy Valentine's Day! <3 Update: More Valentine's Day Activities Added: Early Childhood Ideas: Spark a Lov...

Block Schedule Planning

-

I had an opportunity to teach on a 45-minute traditional class period schedule and a 90-minute block. Both models have their pros and cons. I think my own preference is block schedules because you have so much more time to dive into content. There are fewer transitions and it just seems calmer and more conducive to learning. However, one major challenge is finding purposeful ways to fill that block. If you notice that you are doing one activity for a long period of time, it might be important to think about chunking. What I mean by chunking is thinking of you period in 15-20 minute chunks of time and planning activities within those chunks. I find it's difficult to keep students attention if something lasts longer than 20 minutes, so that was my maximum for any activity (except an assessment). I developed the following sample block plans based on 85 minutes. So, if you have 60 minutes you can think about cutting out one of these pieces. If you teach 90 minutes, add 5 minute...
