I have so many favourites on Underground Maths, here’s one – Scary Sum!
Following on from an area model for multiplication, for your older students, try Divide it up from Underground Maths, a resource designed to help students to make links between multiplication and division of polynomials using multiplication grids. The problem is presented in the image here, but also provided is a warm-up activity and further notes
A favourite Underground Maths resource I have used many times – To log or not to log? This has worked really well every time I have used it. The activity requires students to think about the methods which could be used to solve the various equations. I have always found that in addition to working on indices and logarithms this task has exposed some misconceptions, with students trying to invent some new and invalid laws of logarithms!
Students are often used to problems being posed in such a way that they have all the information that they require in order to start, and no more. Problems (especially from the real world) are very often not like this, and so resources of this type will give students the opportunity to develop the skills needed to deal with this. Some problems might not contain enough information, so students may need to decide on classifications, make assumptions or approximations, or do some research in order to move forward. Some problems might contain too much data, so that part of the challenge is to identify the useful information.
When students are familiar with concepts and ideas they often benefit from exploring them further to improve their understanding. These problems aim to allow this further exploration, and for example, might bring different techniques together, highlight interesting or unusual cases, or probe the definition of mathematical terms.
A resource I found very useful for the matching functions with their gradient functions is Gradient Matchwhich can be used interactively online. See this post on introducing gradients at GCSE. Note that you can simplify the task by giving students the set of six functions and the six gradient functions separately.
Can we fully factorise x4+4y4? Starts with a Show that…. And then we factorise and will need to recall the difference of two squares. We could get very sophisticated and look at those quadratic factors too; useful for those studying the Level 2 Further Mathematics Qualification.
Can we simplify these algebraic fractions? Review algebraic fractions, simplifcation including the difference of two squares and quadratic equations. We could of course also talk about functions (including domain and range.
With November examinations fast approaching, we have many helpful revision resources available. I have created a page,Mathematics – November Examinations 2024, a collection of revision resources. I will add any new resources prepared for the November examinations to this page.
The page is easily accessed from the right-hand menu.
Estimation by rounding by cparkinson3 is is a complete lesson providing a great variety of problems from basic skills to more challenging ones where learners have to apply their understanding of estimation to solve real-world problems. All needed resources are provided.
Functional Skills Included in the Functional Skills collection are Maths Made Memorable, Dr Frost Learning, and Transum Mathematics, all of which offer questions by topic.
The A Level Maths collection contains numerous teaching resources, many of which offer questions that are easily searchable by topic.
