Chancing upon this tweet from Transum proved fortunate. Hidden gems indeed, I had not noticed the Advanced Starters before, some of which I think could be useful for students aiming at the highest GCSE grades as well as for Advanced Level students.
The problem, Find the Radius, illustrated in the tweet is very neat!
I wrote the above in February of last year and I see from Transum’s latest newsletter that The Advanced Starters collection has grown. I see many starters here I like, thinking about next year it’s a good time to check these. With linear courses, starters provide an ideal opportunity for review.
Looking at Coordinate Distance, I can never resist a Desmos page to illustrate a problem! This starter could be also be used to review some coordinate geometry – find the midpoint? Find the equation of the line?
For more on Transum see this post which includes some great Venn Diagrams resources and a reminder that there is a very clear index for teachers and another for students. The extensive library of activities on Transum are all free to use. Activities such as this Algebra resource on Completeing the Square can be checked as part of the free offering.
A subscription offers teachers answers to for example the Advanced Starters and Exam Questions.
