Finding myself absorbed in the details of this story of someone tutoring a student who has learned to dislike math, and how they worked their way to joy (as well as proficiency).

In June 2025, I continued to explore radial designs by arranging heptagons around a central hexagon in a new arrangement! #21CenturyPB #iTeachMath
The designs are displayed in a 3 by 3 grid, featuring 3 unique pattern block designs from my June 2025 collection. The first and third columns show the heptagons that were used to create the radial designs shown in the middle column. The designs are created by using two differently arranged heptagons–the inner layer uses six heptagons of the first arrangement, the outer layer uses twelve heptagons of the second arrangement.

On a fun side note, I've been working on a new board game with my brothers. Really a fun project :-)

We'll Kickstart it in 2026 (first Kickstarter in over 5 years!).

Take a sneak peek below. You can also sign up to get notified when we go live!

The designs feature 4 unique pattern block creations from my June 2025 collection. The first row at the top shows the heptagons that were used to create the radial designs shown in the second and third rows. This collection highlights radial designs created by arranging six heptagons (pointing towards the center) around a central hexagon.

The real deep cut in this comic from @smbccomics.bsky.social is the 37%. That's a serious math reference right there.

It's Mental Math Monday with @mikeflynn55.bsky.social. How would you mentally calculate 88×8 without using any 8s?

This month I’ll be sharing some of my favorite designs from 2025! #21CenturyPB #iTeachMath
The images are arranged in a 4 by 4 grid, with the center four squares merged to highlight a larger design. It features 13 unique pattern block creations from my 2025 collection.

This is how we organised the Prime Climb board at One Hundred Factorial today. (cc @mathforlove.bsky.social ).
A photo of a large section of concrete floor with giant cards laid out, each with a Prime Climb circled number drawn on it. The outside is a ring of fully red prime numbers, except for 0 and 1 near the bottom. Close to this ring are four areas, one where the numbers are coloured yellow and red, green and red, purple and red and blue and red. Then there are fully yellow, fully green, fully purple and fully blue. Between them are ones with a mix of two colours, and right in the centre, ones with at least three colours.

"'6yo: If 0 + 0 is 1, then would 8 times 0 be 4?'

... These “What if” questions are a sign that a child is taking a sort of radical ownership over their mathematical thinking. ... He wants something to be true to explore an idea, so he’s just doing it"!

My 6yo asked me this morning:

"If 0 + 0 = 1, would 8 times 0 be 4?"

I wrote a blog post about it.

Pattern block play! #21CenturyPB #iTeachMath
The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six regular hexagons around a central hexagon. All seven hexagons share the same composition and have 4” sides. The first image along the bottom shows a scaled-up equilateral triangle which is used to create the regular hexagon (with 4” sides) shown in the second image. The triangle is made of 1 teal kite, 2 green triangles, 2 red trapezoids, and 2 pink triangles. The three images on the right show the progression of the design.

We've recently been playing a modified version of Prime Climb with our son. If you have Prime Climb already and want to try playing with younger players (i.e., 6+), try out this version. It's been really fun!

I love working with figurate numbers (see my Square Numbers handout mathinst.com/squareNumbers) esp. Triangle Numbers w/my students but never thought of @mathforlove.bsky.social's 'Step Numbers' (mathforlove.com/wp-content/u...) which now seems obvious to consider! #mathisfun #mtbos #iteachmath

Just in case any of you think my manic enthusiasm for the artistry that is Outer Worlds 2 is exaggerated...

This is ONE of 20+ fully original songs I have heard so far on the 3 in-game radio stations you can tune into as you play.
