A compilation post, featuring:

**BBC Bitesize – new GCSE quizzes****Rob Southern – revision document, mapping his videos to the Pearson texts****Inequalities and linear programming****MEI support for investigating large data sets**

New on BBC Bitesize are **GCSE exam-style quizzes**; the quizzes have been designed for students working on GCSE maths, biology, chemistry, physics, combined science, computer science and geography studying any awarding body specification. For each subject, you will find 50 exam-style questions, these are arranged over five activities of ten questions each. The questions are multiple-choice and students can see a fully worked solution for each question.

Rob Southern has created a very useful **document** linking sections from the Pearson A level textbooks to his videos, where they exist. Rob’s YouTube channel is **Maths in an empty classroom**. Do check **Rob’s site** for his collection of A Level Maths and Further Maths resources. I mentioned his **Coordinate Geometry exercise**, part of the **A Level Pure 1 Year 1 collection** in this **Fill in the blanks post**. Note Rob’s questions to consider to get students thinking hard. You can also find a version on Transum, **Coordinate Geometry Table** which allows answers to be checked.

I do like **Amanda Austin’s latest inequalities resources**, these linear programming style resources would be very helpful for Decision Maths.

For resources for Linear Programming, see these pages in the **A Level Further Mathematics series**.

**Decision Mathematics**compares the specification and shows the subject content of Decision Mathematics for each.**Decision Mathematics Teaching Resources**includes all the teaching resources I have mentioned to date for teaching Decision Mathematics.

From MEI, comes excellent **support for investigating the A Level large data sets**. You will find help videos with useful techniques for using Excel and GeoGebra for statistics in GCSE and A level, also, from** The Advanced Mathematics Support** **Programme **(AMSP) look at these** workbooks** that show how to use Desmos to investigate the large data sets. Desmos could be used to support Statistics at GCSE also.

Here’s a Desmos activity on **Interpreting Box Plots**.

Staying with Statistics, an activity I have always liked is **S4 Understanding Mean, Median, Mode and Range**.

(**All Standards Unit resources**).
