Fawn Nguyen’s Olive problem

Last night Fawn Nguyen posted a neat problem for kids: I thought it would be fun to try out the problem with the boys this morning. My younger son went first (while my older son was practicing viola in the background). He described his approach as “guess and check”: My older son went next. I … Continue reading Fawn Nguyen’s Olive problem

Fawn Nguyen’s incredible Euclidean Algorithm project

Fawn Nguyen recently published an incredible blog post about a project related to the Euclidean Algorithm that she did with her students: Fawn Nguyen’s “Euclid’s Algorithm  The above link is broken, but Fawn’s post is here: https://www.fawnnguyen.com/teach/euclids-algorithm Fawn’s projects are usually very easy to do right out of the box, and this one is … Continue reading Fawn Nguyen’s incredible Euclidean Algorithm project

Fawn Nguyen’s fraction puzzle

Saw this old blog post from Fawn Nguyen making the rounds again this week: Drawing Rectangles instead of Writing Equations and decided to give the problem a try with the kids this morning. Here’s the problem: In a town, 3/7 of the men are married to 2/3 of the women. What fraction of the people … Continue reading Fawn Nguyen’s fraction puzzle

A nice visual pattern from Fawn Nguyen and Bryan Anderson

My own personal style of problem solving has always been heavy on … Continue reading Fawn Nguyen’s geometry problem

A 3D geometry proof with few words courtesy of Fawn Nguyen

Fawn Nguyen is so great at sharing interesting math problems.  On twitter, on her blog, in person, and probably some bat signal type thing if you live in California – she’s got such a great nose for interesting math.   By super happy coincidence earlier in the week we were working through oddly similar problems.  … Continue reading A 3D geometry proof with few words courtesy of Fawn Nguyen

Fawn Nguyen shares a really neat Math Forum problem

Well, I made it exactly one day into the school year without copying something Fawn Nguyen posted.  That probably beat the over under . . . . Cool problem, and one that I asked the kids to work on for part of their homework today. We talked through how they approached the problem when I … Continue reading Fawn Nguyen shares a really neat Math Forum problem

Fawn Nguyen’s influence

A few weeks ago I asked the boys what math they wanted to do for the summer.  They decided on a summer project that they could work on together rather than the separate algebra / prealgebra math we did during the school year.    Not the easiest task in the world given the 2.5 year … Continue reading Fawn Nguyen’s influence
