Had a great day visiting Astrea Academy Sheffield today. Lovely to see @amercermaths.bsky.social in his new role, get to meet the maths department, & see their scholars in action. Some brilliant work going on to close the gaps with Y10 following their mocks & kicking off with Probability in Y8.

I think w.r.t. parents (and it’s still a very small minority of parents) it’s the clickbaity articles on local news and facebook groups where it’s easy to see others expressed outrage without getting the full picture that worries me.

Adam Mercer @amercermaths.bsky.social · 02/01/2025

If I can add my own spicy take similar to this, Covid isn’t fully to blame for the fracturing of home-school relationships, poorer behaviour and attendance as well as worsening MH issues. It accelerated it; but things were getting worse before then. Social media IMO is the real culprit.

I've spent this evening making a second "Is it plausible?" worksheet as my first one was really successful with my Y11's. I've tried to add more money sense questions into this one to help. www.dropbox.com/scl/fi/f60tq... Hope it helps 🙂

I love using shadow papers for feedback lessons, it feels like such a quick win for students (this is how you should have done it, have a go at it again) and it’s great quick win for success and motivation. Really quick to put together too 👍

Adam Mercer @amercermaths.bsky.social · 18/11/2024

I’ve moved to this method recently too. Definitely makes more sense and has a better links to expanding if you do that via a grid too 👍

"Plausible" - When though? 👀

Adam Mercer @amercermaths.bsky.social · 19/10/2024

One of my favourite things this week was playing "Is it plausible?" with my intervention class on MWBs. I gave them some scenarios and discussed whether or not they were plausible... I've made a worksheet of it now with answers👍 www.dropbox.com/scl/fi/lfsy5... #mathschat

followed by changing the subtlety in my own teaching of calculating the lower bound first, then the upper bound, which in turn made error intervals feel more straight forward 👍 #mathschat

Adam Mercer @amercermaths.bsky.social · 28/09/2024

Really enjoyed teaching significant figures and bounds this week. Started off with stuff such as “how much money would actually ask your parents/carers for?” when buying some items, followed later by “give me a number that rounds to 27, that no-one else will put…”

Adam Mercer @amercermaths.bsky.social · 21/09/2024

It’s not created for that purpose mate, it’s in a unit on multiplying and dividing fractions where I want them to have some mixed practice inc adding and subtracting. They’ll have done some unconnected linear problems on the previous pages. I want this to feel different.

#MathsToday #ButYesterdayBecauseIForgot Used this with my 10s post-surds for some reasoning. Love how every time I use this it really hones in on place value as the challenge rather than anything to do with calculation.

Cheers 😊 I'm tempted to add a "For your ones that were "never true" why did you put that?" box at the bottom 👍

Also (though it possibly needs some rearranging) made a "Sometimes, Always, Never" on parts of a circle that I've got to say... I'm pretty chuffed with 👍 #mathschat

This morning's consisted of more task making for fractions problems. "I've used circles, can't really call it a spider diagram then. Got any ideas?" "Bubble map?" Bubble map 👍 🤷‍♂️🫧 #mathschat

Planning my part of our #Mathsconf36 presentation on booklets. Reflecting on what I’ve done in the past, I’ve deffo made some mistakes 😅 (I’m also convinced booklets really are the game changer and look forward to getting that across 😁)

Adam Mercer @amercermaths.bsky.social · 07/09/2024

Something I’ve been better at getting into the habit of is asking the question first, giving appropriate thinking time, then asking the student. Peps McCrea is sharing some great illustrations as to the benefit of this. #rED24

Adam Mercer @amercermaths.bsky.social · 07/09/2024
