How about "find the minimum value of r to 2dp"?

You could also have a maximum area where they have to round the value of r down, rather than using conventional rounding.

In #MathsToday I made 40 A Level teachers colour in representations of the binomial distribution.

This is your regular reminder that if you teach #ALevelMaths you should definitely try to join your local Maths Hub’s A Level Pedagogy group. There is some brilliant stuff going on all over England.

A quartet of representations of the binomial distributions. Screenshots from https://www.desmos.com/calculator/3ea50eafbc

X ~B (10, 0.4)
Shade the diagrams to represent the probability
P(3 ≤X <6)
and draw a numberline.

X~B(10,0.4)
Shade the diagrams to represent the probability P(3 ≤ X < 6) and draw a
numberline.

X ~ B(8, 0.7)
Which is larger:
P(X < 5) or P(X = 6)?

X~B(12,0.36)
P(X ≥ c) < 0.5
What is the smallest possible value of c?

X~B(10,0.4)
Calculate the interquartile range of this distribution.
What is the mode?

X~B(8, 0.7)
P(X ≤ a) < 0.1
What is the largest possible value of a?
P(X ≥ b) < 0.1
What is the smallest possible value of b?

X~B(12,0.36)
P(X ≤ a) < 0.2
What is the largest possible value of a?
P(X ≥ b) < 0.2
What is the smallest possible value of b?

Excited to be running my first session at #Mathsconf39 with @seethelanes.bsky.social

Talking about Variation Theory in #Alevelmaths and how fun it as a guide for writing series of questions!

Here is a set I wrote in #MathsToday for my stats Y12s!

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!

#MathsToday Teaching histograms to year 11 this week and returned to @drrowlandson.bsky.social’s amazing planning series to start. So much deep thought and insight in every post! 🙌 ponderingplanning.wordpress.com/2020/06/05/f...

Filling in the Gaps With Histograms

This blog posts focuses on the sorts of histograms that students see in GCSE Mathematics: histograms with unequal class intervals and where the heights of the bars represent frequency density.&nbsp…

When I went on a tour of my daughter's primary school, something like this was on the wall. I stood there for ages trying to work out what "O" stood for.

In #MathsToday, Year 12 looked at some graph intersections and solving some simultaneous equations, and then sketching the graphs!

A maths worksheet titled “Simultaneous Equations & Points of Intersection.” It shows a grid where different pairs of equations intersect, and the task is to fill in the correct intersection points from a list of given coordinates. Some boxes are shaded and students must explain how many intersection points there are, without calculating the coordinates.

Loving the process of planning yr12 quadratics. Wonderful resource from @meimaths.bsky.social Integral, @susanwhitehouse.bsky.social & @mrsouthernmaths.bsky.social.

Wonderful resources to make it easy to plan for problem solving and modelling without endless exercises. ❤️ #alevelmaths

In #MathsToday, Year 12 and I enjoyed doing some Susan Wall tasks.

I particularly enjoyed this one. We matched the graphs up, and then found the coordinates of all the interesting points.

“Maths question titled ‘Which equation matches which graph?’ On the left, five quadratic equations are listed: (1) y = 6x – 3x² – 3, (2) y = x² – 2x + 5, (3) y = x² – 2x – 3, (4) y = 2x – x² + 3, (5) y = 3x² – 6x + 3. On the right, five parabolas are drawn on a coordinate grid, some opening upwards and some downwards, intersecting around the origin. The task is to match each equation to its corresponding parabola and explain the reasoning.”

Just a reminder that if you are about to start teaching #ALevelMaths, this book is available from the Mathematical Association @mathematicala.bsky.social online shop. In my completely unbiased opinion, it's really quite useful.
