  • Four nice questions for students to ponder at the beginning of your lesson. Some allow for a trial-and-improvement method to arrive at the solution while others require a more methodical approach. All of them may generate discussion amongst the students which could be followed up by the teacher accordingly.

FACT button

Tip For Teacher

Most people don't know all of the wonderful things our calculators can do. There are just so many buttons and functions.

Do you have this strange FACT function on your calculator? Do you know what it does?

Type a number (48 is a good example) into the calculator then press the equals button.

Next press shift then this button with FACT written over it.

You should now see 24 × 3 in the calculator display.

The function performed the prime factorisation of 48.

Very useful.

So this button can be used to find out if a number is a prime number as the prime factorisation function will return the original number.



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...
