Algebra practice sheet with answers scanned in. This sheet was used in a lesson yesterday!

The equation balance from this morning’s lesson

BODMAS revision is a good idea before you start much algebra!

The quiz should open in a new window.

We spent a bit of time on multiplying out terms this morning so I thought the ’slideshare’ above might be handy. Ask questions below!! Just click on the Ask a Question link underneath this sentence.

Just a quick visual reminder of wht we discussed about the straight line graphs

The slide show above isn’t a video. As you click through the slides, you will see worked examples of four types of linear equation, together with a few of each for you to try.

A multiple choice quiz will be up here before the next lesson!

Maths is Fun has a nice interactive straight line graph.

Have a play and see if you can work out what the M and B are for in the formula….

Last Friday, we looked at multiplying out quadratic expressions like

(x + 2)(x + 3) = x² + 3x + 2x + 6 = x² + 5x + 6.

As the BBC Bitesize page explains, you multiply everything in the first bracket by the things in the second bracket, so you obtain four terms. Two of the terms are x terms, and so these can be added together. One way of remembering to multiply out the terms so you capture them all is FOIL

• First - the first term in each bracket, x multiplied by x gives x²
• Outer - the first thing in the first multiplied by the last in the second bracket, x times 3 in this case
• Inner - the 2 times x in this case
• Last - the 2 times the 3 in this case

As always you need to watch the signs!

Try this Web quiz - check your multiplying out of quadratics. A new window will appear with a question and four possible answers, choose the answer you think is right, you should get some feedback. If no questions appear, you need to check that JavaScript is ‘permitted’ by your Web browser.

Close the window after trying the quiz. When you re-load the quiz, you will get a different random choice of 10 questions from 20 questions. I wrote the quiz myself using Hot Potatoes, a free quiz generator program written by a Canadian English teacher.
