# Good Things: Volume 10

*****

My students have continued to enjoy our play table.

I got those on Amazon.

Those are Lego knock-offs from Target the dollar section.

I had a couple students who came early every day to class after lunch and each day they would try to balance a larger cube like that.

I went to a math Ed Camp hosted by MCTM, and it was a great day of connecting with local math teachers!

*****

I’ve already tried a couple ideas people shared at the Ed Camp.  Jess Strom mentioned that she loves combining Open Middle problems with Vertical Non-Permanent Surfaces.  I tried it, and it was my favorite day of Open Middle problems yet! I found that students were more engaged and on task with the problem than when they do it on paper.

Students were working on this problem and this one.

I pulled out Jay Chow’s Desmos Breakout activities recently for the first time this year.  Students always enjoy these so much.  You can find all of his activities here.  If you haven’t seen these yet, check them out!  They are awesome!

*****

The makers of Set came out with a new game, and it’s great!

One of my students had an awesome way of thinking about converting 5/8 to a percent.

“Well, we already wrote 1/8 as a percent today and that was 12.5%, and I know that 4/8 is 50%.  I added 12.5% and 50% to get 62.5%.”

I use this method quite a bit with other types of problems, especially when finding percents of dollar amounts, but I hadn’t thought to use it in this direction – going from fractions to percents.  I love learning from my students!

*****

I had a couple of students debating over multiple days about whether 0/0 would be 100% or 0%.  In this class, we had not been covering percents and this debate was completely student initiated.  We did talk about 0/0 being undefined and sort of an irrelevant question, but they were debating that if you HAD to pick 0% or 100%, which would it be.  I loved listening to their arguments for which one they thought it was.

The last couple years I’ve introduced the Pythagorean Theorem using Notice/Wonder, and I’ve liked how this has gone.  I really like how more of my students continue to think of the what is happening visually after introducing it this way.

*****

Last year I used Dan Meyer’s Taco Cart for the first time.  It was the first 3 Act I’d ever done and it was a spur of the moment decision to try it when I found out last minute that nearly half my class was gone for the day.  I used it again this year, and I felt like I facilitated it a little better than I did the first time.  I made adjustments to how we did this activity on the fly, and I was proud of myself for that.  Students are turning in their solutions on Monday, and I hope to write a short post on how this went soon.

We used one of my favorite Polygraphs recently.  I absolutely love this one for angle pairs in 6th grade.

*****

We had a crazy couple months after Christmas break with several cold days, snow days, and late starts.  We had a brown Christmas, and ended February with normal amounts of  snow for MN.  It’s finally starting to warm up and the snow is melting.  Normally I don’t like this time of year when the snow gets muddy and the grass is brown; however, I’ve never been so happy to see brown grass as I have this year.

*****

Another idea shared at the MN EdCamp by May Vang was to give students examples of a vocal word and have them come up with the definition.  I tried this with rational and irrational numbers, and it didn’t quite go how I envisioned with my first class, so I changed things up with the second class.  It went better, but still not as well as I had hoped.  So I changed it slightly for the 3rd class, and it went much better.  I added some notice/wonder to the prompt, and it made all the difference.  No surprise there.  I don’t know why it took me three tries to add that to the prompt.

A student stopped in my room after school one day this week with a baggie of seashells, “I keep forgetting to bring these to class.  I got these shells when we were on vacation, and they’re for you.”  She thought of her math teacher while on vacation.  How did I get so lucky to be apart of these kids’ lives??

It was a work day in 8th grade this Friday, so I put on some of the NCAA basketball games.  A little math and some March Madness.  I can’t think of a better way to head into the weekend.
