Teaching & Twitter (it’s worth it)

Five to ten minutes. I get in the habit of being involved with Twitter but time passes and it I get “too busy”. This post is that reminder to take the little bit of time in a day and check in. It is so worth it.

On Wednesday, I saw this post:

What a cool idea. Get students quickly working with area and perimeter in an interesting problem solving idea.

IMG_1705On Thursday, a few students were finishing up early on their area/volume project so I pitched this idea and a stack of old newspaper at them. It was fun watching their process. They decided to start with getting the amount of paper to make a square meter.

A few moments later, they realized that their perimeter was going to be quite on the short side. At that point, a student said what could be the quote that makes my year worth it:

 

 

Should we just model it first? 

They sketched out a model of a few different ideas and included a scale.

Once their model was done, they quickly put the newspaper together.

Oops, it can’t be a rectangle so they made a quick adjustment:

A big thanks to @S_ODwyer for sharing her idea and to Twitter for a platform that makes sharing ideas easy. Take a few moments each day to touch base. Hidden gems are everywhere!

  1. How exciting to see your students’ scaled models and problem solving processes! Congratulations, ISB mathematicians! Thank you so much for sharing and connecting. I’ve thoroughly enjoyed reading this blog (and now I’m going back to re-read!). There is a wealth of pedagogy here – with brilliant explanations – to enrich my teaching. Thank you very much. From a teacher & her students in Sydney, Aus.

    • What I really liked about your problem was the connection of construction and problem solving. Finding windows into student thinking is the fun part of teaching and watching them work with the newspaper (great idea – abundant resource with the potential for many iterations) opened up good conversation. Thanks again!
