Lesley @liupinn.bsky.social · 08/10/2026Ooooh...I'd be all into this book. You could do an entire chapter of all the different types of Muppets (e.g. Is Big Bird a puppet? How about Grover? Oscar the Grouch? Snuffleupagus? Slimey?) 120
Lesley @liupinn.bsky.social · 21/09/2026One of the things I love the most is watching kids find the joy in math. Taught my kiddos how to play Under a Million today (a game I came up with to help them practice exponential form). So much engagement and collaboration (along with some strategy development and competition : ) 010

Lesley @liupinn.bsky.social · 25/05/2026The floor plan for Level 0 leads me to believe maybe? But then again, they don't exist in the floor plan for the building 🤷🏻♀️ I did walk up the stairs from Level -1 and see what's supposed to be at -0 (the family space), but I couldn't figure out how to get to +0 via the stairs. 000
Lesley @liupinn.bsky.social · 25/05/2026I wonder how they decided on -0 and +0 as floor options. Also, intrigued by the Braille for - and +. #NoticeWonder 120
Lesley @liupinn.bsky.social · 23/05/2026In Paris for the weekend and managed to see the Granny Life piece by @mathgrrl.com in the exhibit at Maison Poincaré! They didn’t allow any photos in the exhibit though, so just have this one of the catalogue outside :) #MathArt 040

Lesley @liupinn.bsky.social · 01/10/2025Had our Grade 5/6 lunch club fair this morning. Some clubs drew crowds with food. The Math Art table drew crowds with play : ) #MathArt 030

Lesley @liupinn.bsky.social · 15/06/2025Alicja Kwade's WeltenLinie (2017) at the Venice Biennale and the Hayward Gallery in London. It brings to mind #symmetry, but isn't quite symmetrical at all. #MathArt25 141

Lesley @liupinn.bsky.social · 18/11/2024The fifth year of our MS Math Art Lunch Club is off to a gentle start. Fewer kids than previous years, but still the same amount of joy. Today was the first time in all these years that we explored the Fold and Cut Theorem. Lots of exploration, trial and error, and imagination! #MathArt 041

Lesley @liupinn.bsky.social · 29/02/2024Shared this video with my kiddos today and they loved it! I also learned that the un-cancelled cancelled Leap Day happened in 2000. I had no idea back then. thekidshouldseethis.com/post/how-doe... 000
Lesley @liupinn.bsky.social · 08/02/2024Would love any ideas you might have as I start to plan this! 000
Lesley @liupinn.bsky.social · 08/02/2024I've found commercial versions online, but want to try to cut our own set instead of buying one. Will probably not get around to experimenting until late March as our maker space is packed with robotics team work at the moment. 100
Lesley @liupinn.bsky.social · 08/02/2024No as I just thought of it this week! The eighth graders are my first batch of Math Art kiddos (the founding group) and we used to try to do something outdoors at least once each semester and thought it'd be lovely for them to wrap up their time with this as it's a favorite activity. 100
Lesley @liupinn.bsky.social · 08/02/2024The Math Art Lunch Club kiddos had so much fun with the small spirograph sets I cut from scrap acrylic...they even started making little spirograph monsters! It was 30 mins of play and joy. What's not to love? I dream of cutting a large spirograph that will work with chalk outdoors. 130

Lesley @liupinn.bsky.social · 02/12/2023The Math Art Lunch Club that I run for Grade 5-8 kiddos once every fortnight is just the loveliest. Even on a busy week, there is lots of joy. 081
Lesley @liupinn.bsky.social · 20/11/2023I realize that is a formula, but it became so automatic, I never got used to Fahrenheit despite living in the US for almost a decade ;) 000
Lesley @liupinn.bsky.social · 20/11/2023I’ve always just done the old -30 then ÷2 (since I’m a Celsius person all the time way). Which going in the other direction should be easier (double then +30)? Works for most ambient temps, except for the below freezing and heatwave ones, I guess? 100
Lesley @liupinn.bsky.social · 18/10/2023If you have a file handy, I’d love to have my Math Art lunch club kids try this next week : ) 010
Lesley @liupinn.bsky.social · 07/08/2023I've done 'coupons' for various things that folks might need (e.g. covering a recess or lunch duty). Maybe an offer for a coffee (instead of a gift card that might be more expensive than a single coffee + the company)? 010
