Focus on Sets
Set Theory Sets, subsets, intersections and so on. Sets are a mathematical way of classifying objects by means of clear definitions. Any given object has a number of properties that can be sued to classify it and so objects can be in more than one set and so on. With Venn diagrams and set builder notation we can describe and visualise sets and combinations of sets and use them to solve problems. Class...

Thanks  should be fixed now...

Thanks Lois!

Hi, sorry, no it can't... I used this google doc feature a few times because it had some advantages but on balance I am slowly replacing them....

Can this be downloaded as a doc?

There is a typo on Quadratic Links 2, 1st column, 4th equation is x^2 + 2x + 4. It should be x^2 + 4x + 4 because it matches with (x + 2)^2 Thanks for all that you do1

Hi Jim! When I click on "sets of quadrilaterals" it takes me to the "web venns", maybe the link is wrong? Thanks!

Hi Nesreen  I am unlikely to produce an IB style markscheme for this paper, just the solutions, which you already have, but I am happy to answer questions about division of marks etc. No problem. You can either post them here or contact me...

Hi Jim, Any news about the mark scheme. I already solved it, but I want to check the division of marks and some questions ;) Thanks

Hi Jim, Paper 1 question 14 has a typing mistake. You repeated age 12 twice in the table.

Thanks Jim. I actually like it with the raw data left out, as a good talking point for students when they do a practice moderation of this piece. Would suggest amending your B score to 1/3 and showing students how that can make a 1 or 2 mark...

Hi Danny, Makes perfect sense and it is part of a re shuffle I am doing. You will see some 'Focus on...' pages appearing under the main topic headings that do what you are suggesting.... thanks for feedback

Hi Mark I have put a couple of images at the bottom of the page in a hidden box....... there are other solutions of course. These are done with a prism and two pyramids
