Understanding Maths Hacks: 64% of 75 = 75% of 64 YouTube video by Peter Mattock

This is the first in what will be a series of videos exploring different #mathshacks or #mathstricks and the maths that allows them to work. In this video I explore the hack of swapping the percentage and the value in a calculation like 64% of 75.

Open Patterns When we teach students about patterns, we’re really teaching them how to begin to think algebraically. This is especially true when we use Growing Patterns or Visual Patterns from Fawn Nguyen…

A lovely variation of a growing patterns activity from @mikewiernicki.bsky.social. What if we give students an image of Stage 1 (instead of 1-3) & ask, "How might it grow?" B/c they create the pattern, students have "a real 'need' to know how to describe it."

Math learning disability affects how the brain tackles problems, Stanford Medicine study shows Stanford Health Care delivers the highest levels of care and compassion. SHC treats cancer, heart disease, brain disorders, primary care issues, and many more.

Really interesting article from
@stanfordmedicine.bsky.social today examining the difference between how those with maths learning difficulties compare two quantities with those that don't have the same difficulties.

Well worth a read - provides great insights.

Early start this morning for my trip to London to take part in the @mathshorizons.bsky.social session looking at their new problem solving framework.
Looking forward to catching up with many of my friends and colleagues in maths education and getting into a fascinating area of debate.

That actually seems to suggest it is the whole expression - the radical expression. I guess it is one of those things like trapezoid/trapezium. In this country a trapezium has exactly one pair of parallel lines whereas a trapezoid has at least one pair in the US (as I understand it).

Haha, interestingly I always thought 'radical' was synonymous with surd, and didn't realise you applied it to all roots. Is it the symbol alone that it is the radical? Or the whole expression?
