A sequence of checkerboard square patterns with 4, 15, 4, 7, 5, 18, and 19 squares in order.

A set of 4xN arrays with differing numbers of dots corresponding to letters in the alphabet.

Did any of my Canadian friends, fellow Angelenos, or baseball fans catch the World Series themed puzzles in CryptoTiles today? These are a part of a new free math talk resource we have called Tile Talk that you can find here:

I wish this was a museum

Yes, that’s a fantastic idea! So many different ways I could see it working. I happen to have a snub squares tiling I am making on my floor with painters tape and just had a fun little dance on it:

I’ll have to give you a demo sometime! I will send you a DM about it.

Yes that’s a good one that is easy to visualize! Or even is everybody at this table in the class, is everybody in the class at this table?

This looks delightfully simple yet complex, I will have to check it out.

@geonz.bsky.social I was really trying to google to find that somewhere in the world there was a desert called the Cookie desert so I could be right about this but this land hasn’t been discovered yet.

I find when I let kids freely build in Tile Farm Studio they naturally just start asking questions about geometric vocabulary out of necessity to describe what they are doing/trying to do. I was teaching a class yesterday afternoon where so many words came up in a natural context.

A complex tiling with many different types of triangles, quadrilaterals, pentagons, and hexagons.

I think composing shapes out of smaller shapes, or counting shapes in complex composite shapes are great things to get kids flexing their knowledge. Here’s a fun little thing with a lot of geometry vocabulary to talk about that I just whipped up in Tile Farm Studio:

A4 #ElemMathChat

While equilateral triangles are beautiful and elegant and common, I think it’s important to present triangles in as many shapes and forms as possible. I think it’s also important to present non-triangles when teaching what triangles are. And to count sides, even if it is obvious.

Also I think it doesn’t hurt to use an analogy like deserts and cookies. Not all deserts are cookies, but all cookies are deserts. And maybe have students come up with their own examples like that.

To understand all squares are rectangles but not necessarily vice versa, I think it’s important to establish what a rectangle is and isn’t, and all the variations of what it can be, then land on how a square is just a special type of rectangle where all of the sides are equal.

A square made out of isosceles triangles that get smaller and smaller as they go inwards.

So much to squares! They describe special numbers, they are ubiquitously used in art, architecture, and design, they are the basis of how we measure so many things like houses or tire pressure, they have a dance named after them, and can even illustrate subtraction of fractions:

I see geometry in the structure of letters and numbers. I see it in every single piece of furniture in the room I’m in. I see it in all of the art I make. I see it looking out at the horizon at all of the buildings in downtown Los Angeles. And of course in my shoes I designed :)

Hello, excited to be here. I am a teacher, artist, and co-created of Tile Farm, a math education app with a heavy geometry slant.

As a student, I hardly remember any geometry in school outside of 9th grade. Luckily I got a heavy dose of it at home from my geometry loving father.

One of the most fun aspects of last week at #NCTMATL25 was everybody’s enthusiasm for our sneakers designed in Tile Farm Studio. For all of you who signed up for our newsletter, we will be selecting a lucky winner this week to get their own pair! Who knew math could be so fun!?!? #mathmadebeautiful

In my experience a lot of kids “fraction sense” is lower in high school than in mid-elementary. I think they start to get so bogged down with formulas over time that they forget how intuitive fractions are.

At the Omni there was this weird user experience of the elevators having mirrors on the doors so it was really hard to tell which of the 6 elevators was open because they all always looked open.

Wish I had caught this!

My brother solving a CryptoTiles puzzle at #nctmatl25. Come by the Tile Farm booth in the exhibit hall tomorrow to try it out. It’s part of a fun new free resource we have called Tile Talk!

I wonder what fraction of the area of the circles is overlapping!

Feel free to come by the tile farm booth to build something or solve a puzzle!

Great meeting you too! Come by the tile farm booth at some point to figure out the cryptogram on my shirt!

@tilefarmer.bsky.social it was so wonderful meeting you IRL! You are an amazing person!

Post it notes with math equations written on them

My dad is doing some serious math on his complimentary NCSM post it notes he got at the conference. He went through the whole pack, here are some highlights:

A cryptographic font where the number of dots in a column corresponds to the letter in the alphabet.

If you are in Atlanta for NCTM come by the Tile Farm booth! We are debuting our new math talk activity “Tile Talk” which is free and includes a really fun activity called CryptoTiles. Here is a simple kindergarten level CryptoTiles puzzle that says “Atlanta”.

Pair of shoes with a swirling tessellation pattern.

Just arrived in Atlanta with these new shoes that I designed using Tile Farm studio. The tessellation on them is related to the truncated squares Archimedean tiling. If you come by the Tile Farm booth at @nctm.org this week I’ll show you how I made them!
