Watching the #ParalympicGames … and thinking … how many medals are manufactured in total? It’s not possible to know in advance exactly how many medals will be awarded, so I assume more are made than are needed. In which case I wonder what happens to the spare medals.
Something I’ll try next year. To challenge one of the main misconceptions with decimal times, that 2.1 mins is 2 mins 10 seconds, I’ll ask what 2.6 minutes is. Hopefully some pupils will notice this can’t be 2 mins 60 seconds.
Today, for the first time, I introduced completing the square as a way of making 𝔁 the subject in a formula with both 𝔁 and 𝔁² . I think the pupils recognised the value of this more readily than when I’ve talked about maximisation/minimisation in the past.
If n = 5, the Collatz sequence starting at n has range 3n. Do any other values of n produce a Collatz sequences with the same property?
My first brilliant move on @chesscom . Knight capture on c6. I don’t understand why it’s brilliant though. The screenshot is cropped because my previous move was a blunder 🤦🏼♂️.
I’m thoroughly enjoying the new @duolingo learning path. Having previously been stuck treading water, repeating cracked lessons over and over, I feel like I’m making progress again.
An attempt to convince students that each term in the equation must be multiplied by 3. I hadn’t used brackets to explain this before. Students liked it.
This week’s realisation (11 years in). Teach students what corresponding angles are before introducing parallel lines. It’s much easier to convince them to include “parallel” in their reasoning once they see that corresponding angles aren’t always equal.
Thanks for the @chesscom videos on The London System @ginger_gm. Your videos were super clear and I just put the content to good use in Blitz. I had a little cO-Operation from my opponent to be fair.
This school is a genuinely brilliant place to work. I thoroughly enjoyed my 9 years there in various maths roles.
My incredible school @tweetswchs in north-west Essex is about to advertise for a new head of maths. I realise lots of my followers aren’t UK maths teachers, but if you do know some, could you retweet this? I want to explain how amazing my department is!
Can you fill in the grid below using these clues? 1 across is a square number. 3 across has a digital root of 3. 2 down is palindromic. 1 down is prime.
