Presumed Knowledge

You are not required to be familiar with all of the topics listed in the presumed knowledge section of the IB math program, as some will be covered as part of the core. However, by the exam you will need to make sure you understand all of the things listed.

This page is for you to use to ensure you have all the necessary presumed knowledge before the final exam.

Work through the page carefully and ask your teacher about any areas you are unsure of.

There are many references to BBC Bitesize Revision: GCSE math

BBC Bitesize Revision

and BBC Bitesize Revision KS3 math

BBC Bitesize Revision KS3

You are strongly advised to use this link and work through the sections given and do any activities suggested and the "testbites". It will help a lot.

Much of the information in this chapter will be covered in the core of the IB MS course, but it is important that you also do work of your own, to reinforce the concepts covered in class.

The BBC site used is extremely useful for the IB MS course and you will find it useful for revision, it also has links to other good math sites

Plane : A surface containing all the straight lines that connect any two points on it.

Angle : A pair of lines sharing a common endpoint (vertex)
Acute < 90°
Obtuse >90°
(x , y) co-ordinate plane

Go to

Angle

for a detailed explanation, but basically its where you have two axis x and y and you plot ordered pairs, coordinates.
