I love teaching quadratics. I find there it makes a lovely closed universe to explore. And we start with factorising! Today, my favourite factorising task with some low-prior attaining Year 11s. They hate how the numbers are "the same", but it gets them thinking. #mathstoday

💡 No calculators allowed! 😈

A great one to finish a lesson on equating bases. Perfect for testing those laws of indices!

If you can’t identify data that would prove you wrong, you are not really data-driven.

I used this task this week to introduce Y10 to simultaneous equations.

Drawing attention to important decisions that need to be made.

#MathsToday
"What's the same and what's different?" 4 pairs of simultaneous equations with very similar coefficients.

In #ALevelMaths today, our @ncetm.bsky.social GLOW Maths Hub workgroup planned, delivered and reflected on a lesson for my Year 13 group on modelling with trigonometry at North Bromsgrove High School.
Pupils were brilliant, the participants enjoyed it, and all of us are now inspired from this!

More Y9 trig #MathsToday: we ditched the tables in favour of drawing multipliers directly onto the triangles. This lesson went pretty well! Still just using sin and cos, and today I kept everything in one orientation as well.
Three triangles, with working in a ratio table to find a missing length. The same three triangles and answers with the tables removed, and the title How might we skip the table? The reference triangle with multipliers drawn on: x sin(a) goes from the hypotenuse of 1 to the opposite of sin(a), and x cos(a) goes from the hypotenuse of 1 to the adjacent of cos(a). Four questions that have been solved by drawing multipliers onto the triangles

For the next stage of our trig lessons, we looked at the unit circle and introduced sine and cosine as a way to generate a reference triangle for any angle. At this stage they’re still then using similarity and ratio tables to find the missing sides. #MathsToday
We have seen these numbers before... On the left is a picture of the unit circle with an angle of 30 degrees and the sine and cosine lengths marked on. On the right is a triangle with side lengths of 1,0.5 and 0.866 which is labelled 30 degree reference triangle. The ultimate reference triangle: a right angled triangle with an angle a and side lengths of 1, cos(a) and sin(a) Using your reference triangles, write down the value of 1. sin (35) = 0.574 2. cos (35) = 0.819 3. sin (20) = 0•342 4. Sin (5) = 0•087 5. cos (40) = 0.766 6. cos (15) = 0.966 7. cos (10) = 0.985 8. Sin (60) = 0•866 9. cos (80) = 0.174 10. cos (55) =0.574 11. cos (25) = 0.906 12. sin (85) = 0.996 A triangle with sides 22 and an and an angle of 64.5 degrees. Next to it is a ratio table which has been used to set up an equation to find a

After school further maths getting stuck into some trig equation solving. Planned a really precise approach for yr12 (manipulatives, laminated write-on graphs, small steps that move v quickly) and it’s worked really well for year 10 L2FM too! #MathsToday
Photo of a whiteboard showing solving simple trig equations via graphs. First section is only number of solutions, second is values.

Linking ratio and algebra with Y10 #MathsToday
A bar model showing 4 parts for A and 5 for B. Text underneath reads: A : B = 4:5 A is 4 of the 5 equal parts which make B. A is 4/5 of B. A =4/5*B There are similar statements for B is terms of A which are half covered up by grey boxes. 6 questions following the same format as the previous slide. A handwritten annotation next to the first question reads x is _ of the _ equal parts that make y

If we assume that all colors are equally likely (p=.25), what is the likelihood that I would only get 3 or less strawberry Starbursts out of 34?

Binomial X <= 3 with n=34 and p=.25 is less than 2%

Is this evidence that Strawberry starbursts are actually less likely than other flavors #Statsky ?

Y12 have found proof by contradiction really hard! We did some practice at just writing down the opposite statement first (pink in first 2 pics), and then I’ve been scaffolding the proofs fairly heavily.
Does anyone have a good bank of examples for more practice?
#ALevelMaths #MathsToday
If n is an integer and n^3+ 5 is odd, then n is even [in pink] There is an odd integer k for which k^3+ 5 is odd Underneath a proof has been written out, using the following sentence starters which are in a different colour. Suppose that... Then k can be written as... So k^3+5 = which is a contradiction because... So there is no... Therefore… A similarly scaffolded proof that if a is an integer and a^2 is even, then a is even. Pink text reads: There is an odd integer k for which k^2 is even A similarly scaffolded proof that if a is rational and b is irrational, a+b is irrational A diagram to represent the logic behind proof by contradiction. Pale coloured text underneath the diagram reads: If this were true, this would be true, and this would be true,... And this would be true, but I know it can't be. Since my chain of reasoning is watertight, the problem must be at the very beginning, so the initial statement is false.
