If you are in NYC April 19, 2025, Meet the Artist: Topological Crochet Artist Shiying Dong might be interesting to you. https://momath.org/composite-gallery/meet-the-artist/

MoMath used to run an Online Topological Crochet class. I'm not sure if they will be bringing it back, though. https://momath.org/onlinecrochet/

This reminded me of Math Pickle.

Math Pickle (https://mathpickle.com/organized-by-grade/) has a lot of kid-friendly math puzzles that are easy to explain but can become quite intriguing.

I really enjoyed reading "Tales from the Ant World" by Edward O. Wilson. So fascinating!
Re:Simon Tatham's Portable Puzzle Collection on Wednesday July 20, 2022 @10:28PM (#32175091)
I've been a fan of Nikoli puzzles since discovering them through the US Puzzle Championship exam years ago. I always wanted more practice but had a hard time finding paper puzzle books to work with. Especially if I didn't want a book with Sudoku. Anyhow, just a few months ago, I discovered two puzzles books at Barnes and Noble!

Re:Show HN: A Latin self study course, Khan Academy-style on Monday March 29, 2021 @02:56PM (#26626606)
I've recently come across Latin as I was reading "The Well-Trained Mind" by Susan Wise Bauer. It's a book describing how to provide a "classical education" to kids at home. (I'm homeschooling my two young kids this year and reading everything I can about how to homeschool.)

The author strongly recommends having the kids learn Latin. In case anyone is interested, some resources/curricula for homeschooling Latin she mentions in the book include Prima Latina, Latina Christiana, Song School Latin, Latin for Children, The Big Book of Lively Latin, The Latin Road to English Grammar, and Latin Alive!.

Anyone have experience/thoughts/opinions on teaching their kids Latin? Or even learning Latin as a kid?

Acqui-hire for technical talent ahead of a Robinhood IPO? Just speculating here.

This year's FIRST Robotics Lego League Jr's theme is building a moon base. This article is likely too dense for the 6-10 year old crowd but can offer the coach/mentor some discussion ideas!

Re:Inventory of CO2 available for terraforming Mars on Monday July 30, 2018 @01:51PM (#17646453)
Title reminded me of this board game called Terraforming Mars: https://boardgamegeek.com/boardgame/167791/terraforming-mars

For me, each play-through has taken hours but after finally playing it correctly (first two times I played I misinterpreted some crucial rules), I enjoyed the game quite a bit.

I've been compiling Scratch books and here are my (and my kids') favorites:

- Coding for beginners using Scratch (Usborne)

- Code Your Own Games!: 20 Games to Create with Scratch by Max Wainewright

- Super Scratch Programming Adventure! by The LEAD Project

- Coding Projects in Scratch by Jon Woodcock

- Scratch Programming Playground by Al Sweigart

The list above is roughly in order of difficulty. The first two books have spiral binding so they sit flat on the table. I found this to be immensely helpful when my kids first started to use the computer / do Scratch. They could focus on using the mouse and tap-tap-tap typing on the keyboard without losing the page.

Re:The Magic of a Cardboard Box on Monday June 11, 2018 @02:33PM (#17287023)
For building large structures like this, we've found Makedo's are great. https://www.make.do/collections/all-products

The screws and screwdriver make it super easy to connect the cardboard together, and I've found the fit to be surprisingly sturdy. It's reusable and pretty quick to remove from the cardboard once you're ready to take everything down.

The saw, in my opinion, doesn't cut that well. Possibly still better than having the kids use large scissors or a box cutter though.
