Quadratic Formula

You will be required to know the quadratic formula for your exam next week. Some of you have struggled with this so today we’re going to have some fun learning it once and for all. You are going to learn to SING the quadratic formula, to the tune of the popular some “Pop goes the weasel”.

If you can’t remember the song, here it is: Pop goes the weasel

Now for the new lyrics:

Instead of:

All around the mulberry bush,
The monkey chased the weasel.
The monkey thought ’twas all in fun. 
Pop! goes the weasel!

You will sing:

x equals negative b
plus or minus the square root
of b squared minus 4ac
all over 2a!

But before you start, I will show you how it’s done….

Exam Review


This document contains links to blank copies of all the tests and quizzes you have done this year. Nothing (apart from the material in your statistics ISU) will be on the exam that you haven’t covered in these assessments, so they are, in my opinion, the best way to revise. If you really want to make sure you’ve revised well, do them all again, in full. That will certainly ensure that you’ve covered everything in the course.

Independent Study

Many of you will not have worked independently before, but as you approach IB you will be expected to work independently more and more. Here are a few point you might like to bear in mind.

  • Check the syllabus carefully
  • Divide your available time by the amount of work you have to do
  • Give your work a title and add subtitles as you go
  • Define and underline key terms
  • Annotate your work and explain to yourself what is going on, preferably in a different colour
  • Draw diagrams
  • Check your work with your classmates
  • Take responsibility for your learning and make sure you cover what you’re supposed to cover


Stats Unit

This is an independent study unit. The textbook is MYP +2, which is available on the student area of the school file server. There will be no assessment for this unit, but it will appear on you end-of-year examination.

Please work through the following unit outline and keep a record of all your work. It will be reviewed on a continuous basis.
