A follow up to our Tina Cardone geometry project

Had a ton of fun turning a problem that Tina Cardone shared in to a 3D printing project earlier this week: A Cool Geometry Problem Shared by Tina Cardone So when I saw this problem in my son’s Geometry book this morning, I couldn’t resist trying a similar project today: The problem is fairly straightforward … Continue reading A follow up to our Tina Cardone geometry project

Sharing Po-Shen Loh’s new idea about the quadratic formula with kids

Yesterday thanks to a tweet from Tina Cardone I saw a neat article about a new idea about the quodratic formula from Po-Shen Loh: I thought it would be fun to see what the boys thought about this new idea. We haven’t looked at the quadratic formula in a long time – probably at least … Continue reading Sharing Po-Shen Loh’s new idea about the quadratic formula with kids

*Ten 3D Printing math projects to help students explore math

Yesterday I was able to watch the Global Math Project presentations (well, most of them) via the Facebook Live feed. Hopefully those videos will be preserved here: The Global Math Project’s Facebook page One tank that caught my eye was given by Henry Segerman. I’d guess that his work and Laura Taalman’s work account for … Continue reading *Ten 3D Printing math projects to help students explore math

Can an irrational number to an irrational power be rational? (thanks Francis Su!)

Saw this really neat lecture from Francis Su posted on Twitter today: In the lecture he gives a really cool proof that an irrational number to an irrational power can be rational. I can’t remember ever seeing this proof before and I since it uses only really basic ideas about powers, I thought I’d share … Continue reading Can an irrational number to an irrational power be rational?
