Varying some histograms
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…
Exam Feedback
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…
Maths Conf 39 workshop
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…
Integration by Substitution
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…
Factorial Fun
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! @mrlevmaths.bsky.social
Circle Theorems and Trigonometry
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! NLV
Recent Stuff!
Just a quick post to collate together some of the (Mainly A Level) things I have put together over the past few months. Been posting to BlueSky and enjoying it! Differentiation Starter Just a fun little starter for my Year 13s to see what they could remember at the start of the year Linear Interpolation…
Recent Worksheets July 2023
Completion Table Hype Train Been trying to use spare time at work to make some more worksheets and activities – Been on a Completion Table Hype Train recently so that is the bulk of what I am making at the moment – In general just trying to make any worksheet that I need has been…
Surds Extensions
Saw this great question on the 2016 UKMT Senior Maths Challenge and wondered whether it would be possible to make some of my own. I had just been teaching Surds and wanted some nice enrichment that linked surds to indices. I realised that you can nicely create your own by working backwards from the answer…
Creating from UKMT
The wonder of the UKMT I have said before on this blog that I absolutely adore the UK Maths Challenge as a way of massively improving your problem solving skills and using preexisting tools in totally new ways. It’s also an absolute goldmine for interesting purposeful practice. One of my favourite way of creating resources…
Quadratics on Quadratics
Stacks of Quadratics Firstly I would urge you to try the question in the photo yourself. It requires some knowledge of powers and solving quadratics and is wonderfully satisfying to find all SIX solutions. Looking at easier examples Questions like this are a great example of finding creative ways to practice fundamental skills. In this…
Asking for a fence
Farmers’ Area Problems I recently came across this fencing problem posed by two mathematically minded farmers, the first part of which I feel is rather well known. Questions such as these are easy to visualise, meaning you can often give an instinctive answer and then test if your intuition was correct after solving the problem.…
Cracking the Cryptic: Joy and Magic Squares
Magic Squares Magic squares always feel like a go-to end of term fun activity and one I have never given a particularly large amount of thought to – when I saw this question come up on a facebook maths page I am a member of I wasn’t sure how easy it would be but I…
ACTually very interesting
The benefits of doing weird maths This is going to be a short post with some niche maths. Upon discovering that a good friend did the ACT exams instead of the GCSEs that I have done and taught I was immediately intrigued to see what the exam would look like. A bit of research led…
DOTS: One Trick to Solve Them All
The problems: These three seemingly very different questions all showed up in the same SMC paper in 2017. Try each one yourself and see if you can work out what one trick links them all together! DOTS: A Party Trick I’ve always been thrilled by the ability of using the “Difference of two squares” to…
A Digit Problem
I was recently given this problem by a colleague and it immediately took my interest. As soon as I saw it my first thoughts were not “what is the answer?” but “is there an answer? Is there more than one answer? Can I prove this?”. I spent that lunchtime in my classroom looking at the…
Factor(is)ing
Asking “What is Factorising?” The majority of the time, when I hear this question asked in class I have heard the word “Brackets” come up in the response. As a teacher when I hear this answer I generally take it as correct – The student has clearly remembered part of the method behind factorising and…
Factorising by Grouping SB
The Problem As with most of the Maths that I think about I got pretty obsessed with Factorising by Grouping after doing a question on Brilliant.org. (I will not spend too much time here talking about how much I love Brilliant.org but I absolutely absolutely love Brilliant.org and think that anyone that is interested in…
Funky Alternating Sequences
Firstly try the questions! These series are a lovely in many reasons. Looking quite bonkers at first glance they can both be lovingly rearranged or broken apart to make them more accessible. All the series in this post can be split into two smaller more manageable series – for example in the first question by…
Vector and Equating Shenanigans
Part 1: The Question This rather innocuous looking question came at the end of one of our GCSE mock exams and at first glance didn’t seem like it would cause to many problems. Part a is simple enough but part b was basically unlike any question I had seen at GCSE – definitely not a…
Trigonometry Fun
During this Lockdown period the wonderful youtuber 3blue1brown has created a youtube series called “Lockdown Maths” that have been a glorious set of lectures. These are two worksheets I created that directly use puzzles that are mentioned in this lecture: https://www.youtube.com/watch?v=QvuQH4_05LI&t=1501s They are beautiful geometric proofs of some often (and less often) used Trigonometric Identities.…
