Here is a list of what I consider to be the best secondary school maths websites that I use every week.

UK Maths Challenge is the best high school maths website out there, second to mr-mathematics.com. The Questions and Solutions page provide a fantastic range of questions ideal for engaging and challenging any student. I regularly use these questions in lesson and for homework as I like how they promote problem solving and teamwork. The multiple choice answers are great at bringin common misconceptions. The team challenge resources are excellent for gifted and talented classes and fun for end of term lessons.

Geogebra is a fantastic website for teaching mathematics conceptually using an interactive whiteboard. Topics such as: transformations, graphs, angle properties and even data analysis can all be demonstrated using Geogebra. If you can’t find a ready-made applet it is fairly simple to create your own. I’ve made 58 applets ranging from trigonometric graphs to identifying parts of a circle.

This website has a good range of homework tasks for key stage 3 classes. Every worksheet includes a skill, challenge, literacy, research and memory section. I use a worksheet once a week for my key stage 3 classes as most of the topics at this level are covered. There isn’t as much at GCSE (especially the higher tier) but new topics are added on a regular basis.

I like how the homeworks are laid out but I often need to print them as pdfs so I can upload them for the students. Some sheets include an answer page which helps with marking. It would be better if all worksheets included answers.

Excellent website for helping students improve their weeknesses. I use the topic based practise papers as part of the revision process within my department. The expectation is for students to complete two topic papers every week from January to the summer exam. That’s a lot of printing but most kids will print out the papers at home or read the questions on the computer. Having answers and linked video demonstrations available help to reduce my workload and make the students more independent.

When calculating the volume of a pyramid we can substitute the values of the length, width and perpendicular height into the formula V = 1/3 lwh. In my experience this is often provided for the students with little explanation as to why a volume of a pyramid is exactly one third the volume of a […]

When teaching solving 3D problems using trigonometry we begin the lesson with a recap of Pythagoras’ Theorem and the three trigonometric ratios. We do this by matching the ratio and equations to the respective right-angled triangle. Students are encouraged to work in pairs and to show the diagrams as part of the working out on […]

When I teach rounding to a significant figure, I ask the class to discuss in pairs or small groups a definition for the word significant. It is a word that all the students have heard before but not all are able to define. After 2 or 3 minutes of conversation I ask the students to […]

Hi Jonathan,

If you like the UKMT questions, you might like our selection of Short Problems taken mainly from past UKMT Maths Challenges and organised by curriculum topics: https://nrich.maths.org/shorts

We have started to produce printable sheets of the problems; more will be appearing in the next few months…
