In #MathsToday, Year 10 did some Difference of Two Squares questions (the final page of interwovenmaths.com/quadratics).

Outside of #MathsToday, it was nice to see interwovenmaths.com/behaviour get a mention in Craig Barton's 3-Read Friday - eedi.substack.com/p/3-read-fri...
Worksheet on the difference of two squares, laid out as three tables with blank answer boxes beside each question. The first table, “Expand and Simplify”, has six questions (a–f) asking students to expand products of the form (a + b)(a − b). The second, “Factorise”, has eighteen questions (a–r) asking students to factorise difference-of-two-squares expressions, including ones with fractions, decimals, brackets and common factors. The third, “Calculate cleverly”, has twenty-two numerical questions (a–v) such as differences of squares, products like 99×101, and squares of mixed numbers and recurring decimals, to be evaluated using the identity. "1. Why is nobody talking about behaviour? by Nathan Day Nathan is one of my all-time favourite maths resource creators, but here he turns his attention to the subject of behaviour. Nathan argues that behaviour is the missing piece in almost every big conversation in maths education, whether it be problem solving, teacher retention, or attainment gaps. Nathan shows, with a mountain of evidence, how disruption shapes all three, and why ignoring it leaves teachers to bridge the gap alone." from https://eedi.substack.com/p/3-read-friday-130

In #MathsToday, a student remarked on how comparing coefficients of polynomials felt very like comparing components of vectors.

My work here is done.

In #mathstoday (this week 😁), I used prime factor tiles for the first time when teaching products of primes to my lower prior-attaining Year 7s. It worked really well! Printed physical tiles for them from Maths Bot. Definitely recommned. mathsbot.com/manipulative...

#MathsToday Multiple approaches to a counting problem, great observations about a Hasse diagram, and lots of progress on chameleon problems in Discrete today!

Chameleon Island was the last "playground" of the semester. I'm excited to see which scenario students return to for their final project.

Marking Y11 mocks, I’m seeing basic skills costing significant marks.

I’ll be targeting these gaps and using my updated "Be the Teacher" tool to get the students to tackle common misconceptions.

In #MathsToday, Year 10 did some expanding and factorising of quadratics.

Lots of grids were drawn.

(Tasks from interwovenmaths.com/quadratics)
Worksheet task titled “Task 4: Match them up!” A table of twelve cards labelled A to L shows factorised double brackets such as A: (x + 20)(x − 6), B: (x + 20)(x + 6) and H: (x + 10)(x + 12); cards I and K are blank. Below are three columns of four expanded quadratics, each with an empty box for a letter. Three boxes are already filled in: A next to x² + 14x − 120, L next to a blank expression, and I next to x² + 26x − 120. Two expanded expressions are left blank for students to complete. Worksheet titled “Task 6: Expanding More Double Brackets with Grids.” Four rows of four questions. Each question has a box for the brackets, a 2 by 2 multiplication grid, and a box for the expanded and simplified answer. Some questions give the brackets, such as (2x + 3)(3x + 5), (2x + 5)² and (4x − 3y)²; some give only partial grid entries, such as 10x² and 6, or 24x², 32x, 6x and 8; and some give only the simplified answer, such as 10x² − 11x − 6, 25x² − 4 and x² + 5xy + 6y². Students fill in the missing parts to complete each row.

Year 8 were expanding single brackets today. Trying to make sure the misconceptions that you only multiply the first term didn't happen!

In #MathsToday a yr 10 told me they found adding fractions with different denominators easier and more straightforward than expanding a single bracket by a number.

The world has gone mad.

Today was my first Thursday Week A of the Half Term, which means there were no Maths lessons for me to talk about in #MathsToday.

However, my Year 8 Computer Scientists did some practice for next week's Bebras challenge (www.bebras.uk) which has lovely mathematical problems, such as this one.
Puzzle about a binary counting machine with four tilting bars. A bar tilted left equals 0; tilted right equals 1. Three small diagrams show a ball dropping onto a left-tilted bar (0), the bar tilting, and the ball rolling off to the right, leaving the bar tilted right (1). Below is a diagram of the full machine: a tilted rectangular channel with a ball entering at the top right and four bars arranged diagonally, all tilted left and labelled 0, so the machine reads 0000. A play button sits beneath it; the text says the animation shows two balls being dropped, after which the machine reads 0010. Question: after resetting to 0000, what will the machine read once 5 balls have been dropped? Answer as a 4-digit string of 0s and 1s

Year 8s had the squares introduced today, had a lot of practice without them too but the misconceptions were fixed first.

Year 8 started on expressions today so had the virtual algebra tiles using both the x and y. (To get both x and y on Mathsbot algebra tiles change to 2 variables on the top right.)

In #MathsToday, Year 10 did some Pie Charts, including some pie chart puzzles from: www.stem.org.uk/resources/li...

And Year 8 did some 'Best Buy'ing.

I also had a nice conversation about methods for factorising non-monic quadratics. #TeamGrid
