  • Use for KS2 as M/O starter. My year 5 children love it!
  • Julie Reakes, The English College, Dubai

  • It's great to have a starter that's timed and focuses the attention of everyone fully. I told them in advance I would do 10 then record their percentages.
  • Mr Bobingson, Sheeepsinvile Primary School
  •  
  • I think this was a jolly good quiz.
  • Rachel, Carnoustie High School
  •  
  • This was very good because we have just done percentages and we neded more practice.
  • Dawn Roscoe, Auckland
  •  
  • Your other quick calculation exercises have the answers appear after the allotted time which works really well. Any chance of that for this exercise?

% - This is the percent symbol.
Percent means 'out of 100'.

Find 50%:

As 50 is half of 100, then 50% means half. To find 50% of a quantity you need to halve (or divide by two). So 50% of 6 is 3.

Find 10%:

As 10 is one tenth of 100, then 10% means 'one tenth of'. To find 10% of a quantity you need to divide it by ten. So 10% of 800 is 80.

Find 25%:

As 25 is one quarter of 100, then 25% means 'one quarter of'. To find 25% of a quantity you need to divide it by four. So 25% of 20 is 5.

Another way of finding 25% of a quantity is first finding 50% then dividing the result by 2.

Find 33⅓%:

As 33 is one quarter of 100, then 33⅓% means 'one third of'. To find 33⅓% of a quantity you need to divide it by three. So 33⅓% of 30 is 10.

Find 1%:

As 1 is one hundredth of 100, then 1% means 'one hundredth of'. To find 1% of a quantity you need to divide it by 100. So 1% of 800 is 8.

Find other percentages:

Other percentages can be found by combining some of the techniques mentioned above. Here are some examples:

If you need to use a calculator to check your working. See Calculator Workout skill 3.

Zero percent fat free

So if this yoghurt is 0% fat free does that mean it is full of fat?
Does the '0%' and the 'free' cancel each other?

Casio Classwiz Calculator

There is currently a lot of talk about this new calculator being the best in its price range for use in the Maths classroom. The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols but it isn't a graphical calculator as such (it has the capacity to draw graphs on your smart phone or tablet, via a scannable QR code and an app).

As well as basic spreadsheet mode and an equation solving feature you also get the ability to solve quadratic, cubic or quartic polynomial inequalities and the answer is given just as it should be written down, using the correct inequality symbols!

This calculator has a high-performance processor and twice the memory of previous models ensuring speedy operation and superior computational power.more...
