I'm going to try to do #MathsToday as consistently as possible this year (although I might struggle on days when I only teach Computer Science!). Today, in my first lesson with Y10, we did some of @dandraper.bsky.social's lovely significant figures tasks: mrdrapermaths.wordpress.com/2020/11/14/z...

I ran a few CPD sessions for my school on how Excel can make life easier as a teacher this week. We looked at practical solutions to real-life teacher problems. I've recorded them in case anyone finds them useful. (All the pupil data is made up.) www.youtube.com/playlist?lis... #ExcelToday

Designed another interactive poster for my classroom. A student already asked how long it took me to make this. (Not very long thanks to copy and paste.) I have another student who can't wait to draw n=4 of the koch curve. Still looking for more ideas!! #iteachmath #mtbos

Looking for ideas to use my classroom decor to invite my students to interact with math. Not something to distract them, but for the in between times. I have plenty of blocks and puzzles - think more like patterns and posters they can see from their desks. #iteachmath #mtbos #mathart #middleschool

A knight's tour of a 32x32 chessboard. The knight's path can be traced without lifting one's writing implement from the surface of the paper. This tour is close to having 180-degree rotational symmetry and vertical and horizontal mirror symmetries. #mathart #mathsart #chess

A knight's tour of a 32x32 chessboard. The knight's path is unicursal. If you start in the lower left corner and follow the path move by move, you will visit each square once and only once and end near the lower right corner. Inspiration: Szpakowski's linear ideas. #mathart #mathsart #orms #chess

As the year ends, pause: What math stories did your students write—not just in numbers, but in courage, struggle, insight? Growth isn’t always a score. What did they teach you about math, learning, or yourself? #ReflectiveTeaching #EndOfYear #MathEquity #iTeachMath #EduSky

Learning from @pamseda1.bsky.social at the #MathMomentsSummit about how to disrupt the sorting of students that keeps certain kids at the bottom. She's talking about how to teach students so all achieve higher levels (not necessarily the same levels). #iTeachMath #mtbos #EduSky

7s finding the ratio of circumference to diameter. Imagine their surprise when the hula hoop and flower pot both had a value of about 3! It was a cool moment, especially for kids who had heard of π & could sing 100-digits but didn't know why it was special! #HoldingMath #EDUsky #iTeachMath #mtbos

Want to really engage your math students? Let all 21 stand at your whiteboards at once & solve a problem that looks like a butt. This will only work if you refer to it as a butt several times before setting them loose on it! They did great! #mtbos #iTeachMath #EDUsky #BuildingThinkingClassrooms

Teaching students integers with 2-color counters as an introductory strategy. After, we made number lines. Then, a student pointed out there were patterns with addition and subtraction. Watching them generalize in real time... Got them!! #ITeachMath #mtbos
