flipping maths

I’ve created a number of playlists – which should cover nearly all of the key content that you need for HL Maths.  Used alongside a good textbook these should allow you to both prepare for lessons and review them afterwards.  Each playlist has a mixture of lesson content and also worked solutions for past paper style questions.

There’s a really great website been put together to help IB students with topic revision both for during the course and for the end of Year 12 school exams and Year 13 final exams.  I would strongly recommend students use this as a resource during the course. You choose your subject (HL/SL/Studies if your exam is in 2020 or Applications/Analysis if your exam is in 2021), and then have the following resources:

What I like about this is that you are given a difficulty rating, as well as a mark scheme and also a worked video tutorial.  Really useful!

The Practice Exams section takes you to ready made exams on each topic – again with worked solutions.  This also has some harder exams for those students aiming for 6s and 7s.

The Past IB Exams section takes you to full video worked solutions to every question on every past paper – and you can also get a prediction exam for the upcoming year.  I would really recommend everyone making use of this – there is a mixture of a lot of free content as well as premium content so have a look and see what you think.

The IB HL Flipping Maths Videos are grouped into:

Algebra 1

1a) Geometric and arithmetic sequences and series, binomial expansion, permutations, induction, logs:

Revision Videos

8) Revision Videos: A fantastic collection of detailed videos on each topic specifically made for SL maths- but also useful for HL students – you need to know all this as well!  Algebra, Functions, Probability and Statistics, Trigonometry, Vectors and Calculus reviewed in depth (each video is about 40 minutes and goes through all core content with worked examples).  There’s also a comprehensive GDC review of all techniques needed for the paper 2 calculator exam.

Most of the videos are taken from the two fantastic video collections of PatrickJMT and ExamSolutions. Both have even more videos to watch to view topics in more detail.
