Thanks, @seidelj! Currently exploring Cardioid activities using either Geometer’s Sketchpad or pencil/paper. #mathchat #STEAM #STEMed #ValentinesDay #NYCISTk6

Screen Shot 2018-02-13 at 9.57.26 AMLast week, I bumped into Judith Seidel (@seidelj) at a lecture at the Museum of Mathematics. She suggested I explore a Cardioid Activity on Geometer’s Sketchpad  — and just in time for Valentine’s Day too! A quick Google search yielded these resources which I forwarded to the Math Department:

1. A Geometer’s Sketchpad lesson plan:

2. A video tutorial with doable paper/pencil/ruler instructions:

3. More information about cardioids and the math behind them:

Grade 6 designing LEGOS with @Autodesk123D in math with @KKleinNYC. #mathchat #STEAM

Katie Klein (@KKleinNYC) and Jazmin Sherwood’s 6th grade math students are designing LEGOS in this third or fourth iteration of a project that we prototype and revamp each year. In the past, we’ve used a class account on Tinkercad to construct our 3-D shape, and this year students are working with Autodesk’s 123D Design (@Autodesk123D). Tinkercad is part of Autodesk’s 123D family of free apps for 3D scanning, designing, and slicing  apps and software.

In our math project, students solve for the surface area and volume of a one-bump LEGO. Time allowing, they also engineer either a larger traditionally shaped LEGO brick or design a LEGO that isn’t part of a set yet. We are ever grateful to Jeremy Sambuca of The Hewitt School for opening my eyes to this project years ago during a presentation at the now-closed Makerbot store in SoHo.

Here’s the updated lesson plan Katie shared with the children today:
