A vertical number line from 10 to negative 10

Formulae on the Foundation sheet (again, Higher tbd) I had triangle diagrams ready to go, but we ran out of staples so focused on the wording first.

The formulae found on the Foundation formula sheet.

Etymology corner: key prefixes and suffixes.

A selection of important mathematical prefixes and suffixes. DM if you want the full list.

A list of key formulae not on the sheet (focusing on Foundation this year, Higher may appear over summer depending on timetable)

Area of a triangle = base times perpendicular height divided by 2.

When terms are next to each other with no symbol (5y, ab, 6 bracket 2 etc), it means they have been multiplied.

Exterior angles in any polygon sum to 360 degrees.

A polygon with n sides has n minus 2 triangles, therefore has 180 bracket n minus 2 degrees.

A place value table showing column names, then above that equivalent powers of 10, and decimal place position.

Time constraints (will fix it up over the summer), but my provisional display boards! 🥳 First time I've had to curate my own in about 5 years! 😝 #MathsToday #EduSky

Also the bar model version if they want to see why matching x helps to make it a y problem.

The bar model alternative method. Again, DM if you want a breakdown.

This is my layout of choice, using q2a from Corbett's textbook exercise. Happy to break this down later but just give you time to digest/compare to your own. And yes, that *is* a Mr Happy notepad.

My personal method to solve simultaneous equations.

If, by the time you see this, I haven't explained it in replies, please DM me for the full breakdown!

Semi-regular post showing off my Dad because...I mean, look at it! linktr.ee/shaunwrightart to follow his socials/enquire 🙂 (Check out the alt text if you want the origin story of this one)

A pyrography (wood burning) piece of a pufferfish blowing bubbles. The outline is burned onto wood and then he has painted colour onto it.

This piece of wood had a weird shape, and the idea came to him as a result (there is a weird bit on the end that looks like a fish's tail).

Desmos visual to confirm. The green dots show that 00, 01, 37 and 48 are the only such values, seeing as x and y must be limited to 9. Boiled down to 10x+y=x^2+y^2-xy (so close to being a binomial!)

A desmos graph, the original post explains it as best as I could think, but I plotted an algebraic function to fit

On the off-chance that any of you are near the Dover/Deal/Sandwich area, my Dad's doing a craft fair at Solley's Farm next Sunday. Good set of stalls, a nice cafe should you wish to grab food, and a pub about 200 yards away! Details in the poster or alt-text.

The Pub at Solley's.

Christmas Craft Fair.

Sunday 24th November 2024
10AM-4PM

Free admission.

#MathsToday thread (it'll probably be cemented today) For those who need to emphasise to their pupils that incredibly statistically likely does not mean certain, and vice versa, let me present the 2024 Minnesota Twins. This picture is their likelihood of making the playoffs as the season went on.

The graph of the Twins' playoff odds throughout the season, as described in the thread.

So guessing yours looked like this?

x∶y∶z
2∶1
3∶4
6∶3∶4
2x+y=15
3z=12
∴15:12=5:4

I did an FDRP method...does this check out? It's been a long day so I'm aware the middle line could be done without the fraction but meh, and also that I could be missing something obvious!

x:y=2:1
∴2x+y=5y

y:z=3:4
∴z=4/3 y ∴3z=4y

∴2x+y:3z= 5y:4y=5:4

In a way but not that nicely I think. Circle and square prove nicely. Tried with triangle but seemingly not in a way to ensure LHS≡RHS (Everyone feel free to pile on and error check, you can see I'm on a train platform 😂) #MathsToday #UKMathsChat

2) Head of Maths
3) Lead Practitioner
4) Primary School Maths Lead
5) Secondary Maths Teacher
6) Primary Maths Teacher
7) Teaching Assistant

If it were an acronym, it would be GEMS. But it's not any acronym. I slowly build up to this table, the sequence is about 40 slides over the course of a week.

A table of 4 columns

1) Groups (brackets, radicals and numerators/denominators)
2) Powers and roots
3) Multiplication and Division
4) Addition and subtraction.

At the bottom of each column is an arrow going from left to right, showing what to do when you have more than one of the same priority operation. In the 'Groups' column, it also says start inside the brackets, then go outside.

Thing I never get to actually teach but love showing teachers: if you use this visual Pythag proof by Eddie Woo, he normally the shifts the shapes around. But you can prove Pythag without moving anything, just using binomial expansion and area!

Eddie Woo's proof of Pyhtagoras, aligning four congruent triangles into a square (one 'a' side next to one 'b' side), the gap in the middle is a square of length c

So due to my having adults till 8pm on Thursdays, I'm trying to do a bigger meal on Tuesdays where I can bring leftovers and wife can have some too. I figure, why not post 😂 Rotini (fusili) casserole with chicken, broccoli, cauliflower and a cream cheese and chicken stock based sauce

So just did very preliminary digging, can't see a fancy name but a nice proof of it being combinatorics of the various powers of each number. To make it work you need to include 0 indices, hence the plus 1 unlike regular combinatorics. Quickly improvised spreadsheet demo below

My 3 sentence definition for significant figures (alt text provided) #MathsToday (sort of)

The first significant figure is the first non-zero digit in the number.
The final significant figure is the final non-zero digit in the number.
Anything in between is always significant.
