I had the absolute pleasure of completing TS1 which was a half year A Level Stats CPD that was some of the best maths specific PD I have had. I did it alongside one of my colleagues Shane, and we had a great time getting more comfortable with stats each week and then meeting other teachers in the in person events.

As part of the final assignment we chose to create resources we could take back to the department based on each of the questions we were asked to complete.

Here is a link to a pdf of all the resources we made and the PPT

Resource 1: Probability from Venn Diagrams

Wanted to create a resource with loads of set notation practice and get students used to potential algebraic probabilities. Also nice extension with triple venn diagrams.

Resource 2: Simple Binomial Probabilities

Simple probabilities from two different binomial distributions, lots of practice but each question thinking about how the inequality has changed and how that would affect our answer.

Resource 3: Hypothesis Testing

All of the things you need to practice Hypothesis testing, questions mainly taking from textbooks/resources just creating a structure where students need to do all the things

The table doesn’t photograph well so its in the pdf here

Resource 4: Probability Distributions

Not a topic that we found lots of resources for so we had a great time putting these together.

Please do let me/Shane know if you end up using/liking any of these!

Thanks for reading

Having just done some phenomenal CPD as part of AMSPs TS1 course with a colleague I have been teaching Hypothesis Testing to my Year 12s over the past two weeks.

I wanted to create a structured flow for them to work through and practice so we created the table here (It needs to be printed in A3)

Some of the questions don’t have enough information to be fully completed! It was interesting to see which things students were/weren’t able to fill in and why!

The second page should also get them to think abit more deeply about what they are doing and flow through the question in a different way!

I have found that as we getting more students come into A Level maths with grade 7s as opposed to 8s that the need to scaffold longer questions has become more important and I’ve really enjoyed starting to put together more A Level resources that answer the question “How would I teach this topic if I was teaching it to my year 10s” which has been really fun!

Let me know if you have any thoughts!

Finding the median from a Histogram is one of those A Level Topics that sneaks into GCSE and that I had actually not prepared to teach when it came up whilst we were doing some of the fantastic Focus Tasks from Mathsbox. I quickly printed off some blank axis from Desmos and then went about writing some simple histogram questions under the visualiser.

The issue with making these questions up on the spot is that they weren’t all “nice” and didn’t really build up in difficulty properly.

So I speedily during lunch put together the following PPT that introduced the idea of Linear Interpolation slowly

It actually was a lovely opportunity for some Variation Theory – Something I hadn’t really thought about in this context before!

There a bunch of these questions in the PPT and then build up to some more tricky questions – but all nicely contained on a small grid which was nice

Also meant that we could also do mean from a Histogram etc.

Always fun to put something like this together that I can then use for my Y12s in the future.

Thanks for reading!

We have been doing Year 11 mocks recently and I always love making worksheets based on questions that were answered weakly by my classes.

Here were three of the “worst” answered questions that I would’ve liked them to get.

For this one I made a Table that slowly built up difficulty and ended with some nice extension questions where you form quadratics from indice equations

This one just needed a few practice questions:

Finally part (c) of this question was actually quite a tricky version of this type of question so I built it up slowly starting with drawing extra graphs onto x squared

Before moving onto a harder quadratic

Then got the students to work through a worksheet of a bunch of the questions that get quite tricky!

Very enjoyable!

A Level Variation Theory

Had an absolutely glorious time running a workshop at Mathsconf39 with my colleague Shane a couple of weeks ago.

I have attached the PPT that we used at the top of this post so people can use it in department meetings as CPD or just to take a look at some series of questions.

The biggest take away from the session is that designing questions based around getting our students to think deeply is great from students but also just fantastic CPD. We start our department meeting with a slide such as the one below and then discuss the differences and similarities between the questions that we have written. So much fun!

Some of the mathematical behaviours we want students to have:

Big shout out to Craig Barton for the fantastic book and websites

If you came to the session and have any feedback for us please do email us here 🙂

Thank you!

I always like using simpler integration by substitution examples to start of, things that students know how to integrate already that we can then use substitution to do before moving onto trickier substitutions.

Got the above questions from Underground Maths – added a couple of limits but that’s it – such great questions

Finished off with some trig substitution ones. PPT here:

Odds and Evens

Had a fun time planning a one off hour lesson prepping students for the Intermediate Maths Challenge so we took a look at factorials, in particular looking at properties of their factors. Put together the following PPT and had a great time!

Let me know your thoughts!

Inspired by interwoven maths made a worksheet combining triangle problems with circle theorem problems. Was a bit fiddly on PPT but fun! Answers on the PPT 🙂

Enjoy!
