An introductory mathematical induction problem I learned thanks to Kelsey Houston-Edwards

Yesterday Annie Perkins asked about resources to help a student understand mathematical induction: Looking for some resources I was reminded of this incredible video that Kelsey Houston-Edwards made in 2017 – the proof by induction example starts around 5:25: Today I thought it would be fun to have the boys go back and work through … Continue reading An introductory mathematical induction problem I learned thanks to Kelsey Houston-Edwards

Sharing Kelsey Houston-Edward’s complex number video with kids

I didn’t have anything planned for our math project today, but both kids asked if there was a new video from Kelsey Houston-Edwards! Why didn’t I think of that ðŸ™‚ The latest video is about the pantograph and complex numbers: Here’s what the boys thought about the video: They boys were interested in the pantograph … Continue reading Sharing Kelsey Houston-Edward’s complex number video with kids

Revisiting Kelsey Houston-Edwards’s Hypercube video

Last week Kelsey Houston-Edwards published a fantastic video about hypercubes – it is one of the best math videos I’ve ever seen: Here’s our project on her video: Kelsey Houston-Edwards’s hypercube video is incredible! Today while the kids were at school I wrote a couple of Mathematica functions to replicate her results. Writing the code … Continue reading Revisiting Kelsey Houston-Edwards’s Hypercube video

Kelsey Houston-Edwards’s hypercube video is incredible

The latest video that Kelsey Houston-Edwards released is one of the best math videos that I’ve ever seen: This morning I used the video for a project with the boys. We watched (roughly) the first 11 minutes. I stopped the video before the Houston-Edwards revealed shapes associated with the 4D cube. Here’s what the boys … Continue reading Kelsey Houston-Edwards’s hypercube video is incredible

Sharing Kelsey Houston-Edwards’s topology video with kids

Kelsey Houston-Edwards’s latest video is terrific: This one is particularly easy to share with kids because there are several puzzles where she asks you to stop and think about the solution. I began the picture frame puzzle as the starting point for our project today. The puzzle goes roughly like this: A common way to … Continue reading Sharing Kelsey Houston-Edwards’s topology video with kids

Sharing Kelsey Houston-Edwards’s bridge video with kids

Kelsey Houston-Edwards published another fantastic video this week: By coincidence my kids had been making domino runs this week and I was already planning on doing this bridge activity with the boys – perfect timing! Even better, Houston-Edwards’s video shows that this activity is a great way to introduce kids to basic mathematical modelling. That … Continue reading Sharing Kelsey Houston-Edwards’s bridge video with kids

Sharing Kelsey Houston-Edwards’s Cryptography video with kids

I’m falling way behind on Kelsey Houston-Edwards’s video series, sadly. Her “How to Break Crytography” video is so freaking amazing that it needed to be first in line in my effort to catch up! So, this morning I watched the video with the boys. We stopped the video a few times to either work through … Continue reading Sharing Kelsey Houston-Edwards’s Cryptography video with kids
