Jake Gordon has been rather busy! Have a look at his “monster of a PowerPoint”. These detailed worked examples are based on the book Teaching math with examples by Michael Pershan.
I've just uploaded a PowerPoint with all the maths worked examples I've made so far. It's a 400+ page monster, and it's totally free to help you teach maths. https://t.co/hNYSQWfoQ6pic.twitter.com/Q66k7KdQMe
Also inspired by Michael Pershan’s book and her research on self-explanation, have a look at Karen Hancock‘s journey into worked examples.
From Nathan Day – a brilliant collection of resources on Distributivity: Partitioning, Grid Method, and Expanding Brackets The 15 tasks increase in demand. Note the complete thread.
Andy Lutwyche’s collection of Erica’s Errors where students must identify errors in solutions can be an ideal starter for either retrieval practice for an earlier topic or to consolidate learning for a current topic.
If you’re thinking of reviewing your primary maths curriculum this year, make sure you’ve had a look at our curriculum mappings: ⭐ Carefully-sequenced steps ⭐ Lesson slides ⭐ Pedagogical supporthttps://t.co/3ae8uXhFRkpic.twitter.com/ygXeon4Ikq
From the GCSE/IGCSE/L2 Further Maths page, the pages for individual topic areas all include Sites with clear resources by topic, see the Algebra page for example. These resources by topic include links to the relevant DrFrostMaths key skills.
GCSE Content 17. solve linear equations in one unknown algebraically (including those with the unknown on both sides of the equation); find approximate solutions using a graph
Desmos – Solve equations bar models Maths White Board
On Matt Woodfine’s Maths White Board, from the home page use the filter to choose Algebra and search on linear equations.
Math Whiteboard
On Math Whiteboard start a new board. On the right-hand side of the top menu select the three dots for More and then Highlight equivalence.
You can type expressions on a whiteboard and equivalent expressions will be highlighted in the same colour – brilliant. (For more on this feature – see Highlight Equivalence.
The ability to display or hide the variable and to take snapshots means working can be clearly shown using this PhET Sims Equality Explorer. Math HTML5 PhET sims by topic see PhET Sims – Index.
On the SERP website before see MathByExample and AlgebraByExample which is a set of Algebra 1 assignments that incorporate worked examples and prompt students to analyze and explain. These resources can provide prompts for discussing common misconceptions.
On Dr Frost Maths we can use any of the reosurces here on linear equations or perhaps try his full coverage resource – if you want a compilation of GCSE questions.
I think this ‘cover up’ method seen here on Don Steward’s Median can be helpful for many students, something I have used sometimes in class where students are finding solving equations challenging.
Graspable Math is easy to use, I decided I would solve an equation and wanted to show all the steps. To start, go to a blank canvas and choose Insert / Math Expression, I have used the method of selecting and holding the = sign to start as you can see illustrated in the video above; I was then able to enter an operation to apply to both sides of the equation.
Using my GCSE Algebra page which includes the GCSE subject content and resources, note also the sites easily searchable for algebra resources by topic. Several examples from these pages are given in this post for further resources from other sites on that list:
Back in Mathematical Miscellany #46 revisiting some of the much older Miscellany posts to remove broken links I was reminded of some resources still available after many years.
For today a small selection of some resources from older posts. From 2011, we have a dance for teachers of Decision Maths – Dancing the Bubble Sort! I see AlgoRythmics celebrated its 10-year anniversary in 2021.
I’ll finish with slides from a session I presented at last year’s MA Conference on Enduring Websites – some sites that have been with us for many years and all still there!
On my page on A Level worked examples, I highlighted the My Revision Notes books from Hodder. Many books are available in the My Revision Notes series, most with a free document of worked examples; questions and fully worked solutions for each section of the book are provided, whilst the documents refer to the books, they are complete in themselves. It’s good to see a book with this document for the International GCSE Mathematics from Pearson. I have added this to the IGCSE page.
Visnos Visual Numbers
Visnos Visual Numbers
A recent interesting online discussion recently on some students using only digital devices for telling the time made me wonder about resources for telling the time using a clock face. Looking at the KS2 programme of study, I see references to clocks, including tell and write the time to five minutes, including quarter past/to the hour and draw the hands on a clock face to show these times. Have a look at this demonstration, Time Angle and Fractions from Visnos Visual Numbers. I was happily distracted by many of the other demonstrations!
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.
Another page with a new section is the A Level (16+) resources page from the A level series where I have added a section on sources of exam practice papers.
A reminder that MEI’s Ritangle competition begins on Monday. Do have a look at the questions from previous years (scroll down), full solutions are provided, these are a great source of questions for students studying A level Mathematics, the International Baccalaureate, Scottish Highers, or any qualifications with equivalent content.
Get the date in your diary, Ritangle returns on 3 October!@Integral_Maths's exciting competition for A level students is back, will you be this year's champion? 🏆 pic.twitter.com/4eYG4FhFyP
