A variety of “Step Puzzles”. 4 circles are linked in a row and joined with another row of circles. Different numbers are in a few of the circles. The student has to fill in the empty circles with numbers to complete an arithmetic sequence. Each puzzle has a unique shape. For example, the two rows of circles might make a “V” or a “Y” shape.

My students liked these arithmetic sequence number puzzles when we were trying to learn something similar. mathequalslove.net/step-puzzles/

I’m not sure if you’re saying I should have chosen something from A Christmas Carol…or calling me a muppet.

A whiteboard with 5 questions where the discriminant has been used to find the number of solutions to a quadratic

I was rubbing this off the board as Y7 came in for the next lesson, and two of them asked why I was teaching discrimination in maths. (I told them they’d have to do A Level to find out!)

Did I do #FridayFive right Ben?

#Mathstoday
Got to start expressions with my other year 8 group today.

Cuisenaire rods in a staircase formation, missing the brown rod. Alongside a picture in a book with a similar staircase with the same rod missing.

Making progress towards the picture on the book.

Me: Are you sure that staircase is right?

4yo: Yep, I’m making the picture in the book.

Four linear sequences all starting at 7 and ending at 19 but with a different number of gaps to fill for each (1, 2, 3, 5)

I used this yesterday with Y7. The number line helped them get their heads around the idea that there is one more "jump" than blanks to fill.

#MathsToday

12 different percentage questions all involving 240 and 40.

In #MathsToday with Y10 we did this set of questions.

I let them choose their preferred method for each question. My model solutions were a ratio table with 100% in the top-left for consistency.

Maths task suitable for KS4 students - solving quadratic equations by factorising then sorting them according to their solutions.

Maths task suitable for KS3/4 students - nine linear equations to solve where the coefficients of the x terms are fractions.

It's been a few weeks since any updates, but here are some new resources from this week's teaching of solving equations:

She’s not on here.

If you assume the 1 has to be the thinnest I suppose.

Thinner strips on the area model.

Not sure what’s going on with the little ones though?

Every time I visit my mum I’m always reminded of these mathematical placemats.

Just over a week until publication of my new book on the joys and power of curiosity - the perfect gift for someone interested in maths or politics or archaeology or physics or art or poetry - also ideal for anyone not yet interested in those things who should be.

Ha, I was going to say “add extra zeros as required!”

£25.20 with 9 division calculations around it (from 2 to 10)

A great total to have if you want to split a bill evenly in a restaurant.

I’ve been trying to explain this to @bennewmark.bsky.social for years but he always gets angry with me for some reason.

The diagram shows two squares, OPQR and OSTU. Point S lies on QV. Triangle UQV is isosceles with a right angle at V. Square OPQR has area 25. What is the area of square OSTU? A 36 B 45 C 50 D 54 E 60

Enjoyed Q25 from the SMC and in particular liked that my own solution isnt one that is demonstrated in their videos

Round these numbers correct to 4 decimal places. a) 0.3333... b) 0.5555... c) 0.3535... d) 0.5353...

A silly bit of interweaving or a useful task?

You add crushed bay leaves in the top then pour boiling water through it for an intense flavour hit to any dish.

Of course!

A poster full of misconceptions such as "Addition and multiplication makes things bigger​" and "Two negatives make a positive​"

A brain dump of mathematical misconceptions.

Which of these might be avoided through careful teaching?

There is some. For example, in our context we have a large proportion of EAL pupils who are good at algebra. These pupils can perform better on higher tier paper.

Left: Requires triangle-interior-angle-sum and straight-angle-sum. 3 steps. Slower?

Right: Exterior Angle Theorem (Euclid 1–32). Requires corresponding and alternate angles. 1 step. Faster?

Right feels cleaner to me ... I wonder what pupils would think?

Sorry, I did a maths joke. 60! Is a really big number.
