10 Lego Math

Last week during our Bike Rodeo in PE, we did a math investigation around how many wheels were on the bikes in our bike row in the gym (yeah, I know…I should have shared that post first.  Sorry. 🙂 ).

It was our first try with math notebooks and working to communicate our mathematical thinking in words, pictures and numbers.  Kiddos are expected to be able to do that thoughtfully and clearly, based on this rubric:

As I looked over the work kiddos had recorded in their notebooks, I noticed that kiddos mainly just wrote numbers.  Ok, really a number.  Just the answer to whatever question they were working on.  The words and pictures parts were pretty much MIA.  It’s still early, so this is neither surprising nor worrisome–we just need some work on what it means to clearly and concisely show what we did to solve a problem.

While we could have done this in a variety of ways, I took a super smart suggestion from my friend, Mrs. Marks, (who you might remember inspired this Lego Leading/Following lesson) who thought she would walk a bit backward and have her kiddos work on just representing something really small they that had counted, made, etc.  Perhaps because the first “Mrs. Marks” lesson was using Legos, or maybe because they’re the best tool ever, or we all love them or we have a TON of them….but regardless, I framed our next communication lesson around a Lego creation invitation.

With the goal being using words, pictures and numbers (as necessary) to explain their thinking and making their explanation match their creation, kiddos were given a baggie with 10 random Legos.

Then I gave them these directions:

For the first part, kiddos only worked on steps 1 and 2.

As we moved to the next step, I did a think aloud as I drew and then wrote about my own creation.  We talked about what information would be helpful to know if they were going to build a replica of my tower (because that’s what they will be doing next!).  They gave great suggestions of words to use and we revised and added to the words, also discussing what labels might be helpful.

Somehow I didn’t get a picture of my tower, but I promise it looks just like that drawing. 🙂

Kiddos’ next step was to work on their drawings and writing, with nudges along the way to add or revise to make sure their thinking was clear and complete.

Today we finalized our thinking, took a picture (to compare our drawings and creations) and posted our work on Seesaw.  We used the recording feature to read our writing and add any details we thought were important.  Next step is that we will build each other’s creations and discuss what information in our work was helpful, confusing, and/or missing.  We will then try again with another creation and see if improve.  Kiddos have been so excited about this work and I’m excited to see how it impacts our math work going forward.

How do you use Legos to learn?  We’d love to hear your ideas.  🙂
