Fractals in 6th Math with @kkleinNYC, Geometer’s #Sketchpad, @Scratch, and pencils. @The_School #mathchat

I’ve had a deep love and respect for Geometer’s Sketchpad since I was first introduced to it in 1994 as an undergraduate Math major (and aspiring math teacher) at Bryn Mawr College.

Later, I used Geometer’s Sketchpad during my student teaching stint at Strath Haven High School and again as a pre-Algebra/pre-Geometry teacher at The Dalton School.

Today in 6th grade Math at The School at Columbia University, Katie Klein (@KKleinNYC) and her associate teacher, Jazmin Sherwood, facilitated a great lesson on Fractals blending direct instruction, video, and self-paced sketching with and without technology.

1. Homework from the previous night was to watch the first 20 minutes of Fractals, Exploring the Hidden Dimension.

2. Here’s a link to beautiful photos of fractals found in nature:  http://io9.com/incredible-photographs-of-fractals-found-in-the-natural-480626285

3. Here are instructions for drawing Sierpinski Triangles with paper and pencil:

4. Here are instructions for drawing Sierpinksi Triangles using Geometer’s Sketchpad on their laptops:

5. Here’s another resource for making other fractals with Geometer’s Sketchpad:  http://www.gwinnett.k12.ga.us/PhoenixHS/math/GSP-website/17_Fractals(51-61).pdf

6. With additional time, students could explore fractals with Scratch or Snap (both are web-based block-based programming environments). Here are some links I gathered:

My contribution to @The_School’s celebration of Poetry Month: “If We All Were Robots” by Jaymie Gerard

Our current duo of librarians at The School at Columbia University are Nadine Renazile and Talia Neffson.

As per previous years, The School celebrates National Poetry Month by having students and faculty read poems every morning over the intercom system. Shel Silverstein is a popular choice.

Nadine poked her head around the door (her space shares a wall with the Educational Technology Department’s office) and asked if anyone wanted to read a poem with a technology theme. I searched for poems about robots, and after reading a bunch aloud to Dylan Ryder, we settled on If We All Were Robots by Jaymie Gerard.

If we all were robots
Instead of girls and boys
Maybe we’d have humans
To play with as our toys

We’d keep them in our closets

And take them out for games

We’d dress them up in little clothes

And give them funny names

We’d take them to the marketplace
We’d take them to the pool
We’d listen to them singing songs
And send them off to school

We’d see them getting taller

We’d help them as they grow

We’d wish that they’d get smaller

But they don’t do that, you know

They’d grow up to be astronauts
And presidents and kings
We’d pretend that we were humans
So we could do human-like things

So we might as well be humans

If we ever get the choice

‘Cause who’d want to be robots

When we could be girls or boys?

Dylan and I simultaneously had the idea to have the computer read the poem aloud using the voice of Alex, the most human of the text-to-speech accessibility options in the Mac OS. I had to add inauthentic punctuation to change Alex’s cadence, but here’s the finished product (just close your eyes)…
