Another great problem from Fawn Nguyen (2 of infinity)

Earlier this week Fawn Nguyen posted a nice conjecture from one of her students on twitter: 6th grader made claim: if you multiply 2 consec #s, say 5×6, then the square of the middle # (5.5) is the same product, plus 0.25 — Fawn Nguyen (@fawnpnguyen) January 9, 2014 I love Fawn’s approach to teaching … Continue reading Another great problem from Fawn Nguyen (2 of infinity)

10 fun geometry ideas to share with kids – inspired by a Jordan Ellenberg tweet

I saw an interesting tweet from Jordan Ellenberg earlier this week – here’s writing a new book on geometry and was asking for suggestions for neat geometry ideas people have seen: Having spent close to 10 years now searching for fun math ideas to share with kids, the tweet from Ellenberg was a good motivation … Continue reading 10 fun geometry ideas to share with kids – inspired by a Jordan Ellenberg tweet

15 (+1 bonus) Math ideas for a 6th grade math camp

Saw an interesting tweet last week and I’ve been thinking about pretty much constantly for the last few days: I had a few thoughts initially – which I’ll repeat in this post – but I’ve had a bunch of others since. Below I’ll share 10 ideas that require very few materials – say scissors, paper, … Continue reading 15 (+1 bonus) Math ideas for a 6th grade math camp

A project inspired by Steve Phelps’s Dissection tweet

I saw a neat tweet from Steve Phelps today: We’ve done a couple of projects on the Rhoombic Dodecahedron before – here are three of them: Using Matt Parker’s Platonic Solid video with kids A 3D Geometry proof with few words courtesy of Fawn Nguyen Penrose Tiles and some simple 3D Variations After seeing Phelps’s … Continue reading A project inspired by Steve Phelps’s Dissection tweet

10 complex, rich tasks to recommend after seeing Geoff Krall’s Shadowcon talk

Earlier today I saw a link to Geoff Krall’s Shadowcon talk. In part of the talk he made the case for sharing complex, rich tasks with kids. I might not have the exact words right because I’ve completely failed to find the link to the Shadowcon talks I saw this morning so I can’t find … Continue reading 10 complex, rich tasks to recommend after seeing Geoff Krall’s Shadowcon talk
