For those of you who were using Seesaw for student portfolios/feedback/SBG, what’s the new alternative platform (now that Seesaw doesn’t allow individual teacher accounts for multiple classes)? #iteachmath #mtbos

I’ve seen some wild outcomes at the target over the last 13+ years of coaching this sport. More Robin Hoods than I can count on two hands. But THIS?? This was a first. 👀

Arrows in a target. One arrow is barely touching the target at the point of the tip.
There is a direction down emoji pointing to the arrow tip and an emoji of an exploding head.

Long shot BUT does someone have the HS version of this that they’d be willing to swap for the K-5 version? I bought this and never needed it.

If you need a new/free puzzle site, I just saw www.ponderclub.co by two indie developers on TikTok. “Thoughtful games for restless minds.” 🫶

Four rounded square tiles arranged in a two-by-two grid on a light background. Top left is a blue tile labeled “Common 3” with a Venn diagram icon and the subtitle “Arrange words by theme.” Top right is a peach tile labeled “Sudogoose” with a goose icon and the subtitle “A lighthearted spin on sudoku.” Bottom left is a green tile labeled “Slideways” with a horizontal arrow icon and the subtitle “Find all possible words.” Bottom right is a pink tile labeled “Wordie” with a grid icon and the subtitle “Guess the 5-letter word.”

Four large rounded tiles arranged in a two-by-two grid on a light grid-pattern background. Top left is a gray tile labeled “Mini 5x5” with a small crossword-style grid icon and the subtitle “Bite-sized crosswords.” Top right is a teal tile labeled “Color Flood” with a paint bucket icon pouring paint and the subtitle “Fill the grid with one color.” Bottom left is a yellow tile labeled “Double Up” with stacked blocks and upward arrows, with the subtitle “Combine same numbers.” Bottom right is a purple tile labeled “Digit Shift” with numbered tiles 1 through 4 and the subtitle “Arrange digits in order.”

Just noticed this page in the back of my Hobonichi weeks planner. Would be a cool idea for students to use in class (if I was still teaching middle school) at beginning, middle, and end of year (since most of them, unlike me, GROW in their teens😆) for data, percents, etc. (except for bare feet🤢).

Hobonichi Weeks page encouraging user to write down common measurements proportional to their size (including icons). Ex: thumb to pointer finger, thumb to pinkie, elbow to longest fingertip, heel to toe (with and without shoes), stride when walking normally , wingspan. Also includes sizes of common items like credit cards (3.4”x2.1”), A4-size paper (8.3”x11.7”), letter size paper, Hobonichi Techo Weeks cover (3.7” x 7.4”).
Has a ruler in cm down the right hand side of the page.

I developed a new math talk routine I’m calling Guess Y? I’d love some feedback. Check out the image and let me know what you think the Y axis could be. #math #teaching

The image shows a coordinate grid Q1 with peppers below the x axis. From left to right is: Bell pepper, poblano, jalapeño, cayenne, habanero, ghost, carolina reaper. The y axis is labeled with a question mark. The graph shows a negative slope going from the highest visible point above bell pepper to 0 over Carolina reaper.

As much as we ought to ridicule this administration and their stated goals, it's not lost on me the human toll that this administration continues to exact on vulnerable people across the world. It's downright ghoulish the way empire flippantly discusses death over text. We deserve a lot better.

Hi friends! I have a book coming out next month! It is full of *gorgeous* photos such as seen on the cover here. There is one really fun photo that didn't make it into the book...

Book cover for How Did You Count? There is a sideways diamond of shiny plastic spheres carefully arranged on a wood floor. The left "half" of the diamond is a triangle with base five, made of light blue spheres. The larger, right "half" is a triangle with base six, made of red spheres.
