Maths-Magic Instant Addition

This is more than just an assembly... it's a maths activity that will inspire and entertain. You can also use it as a superb introduction to some great mathematical reasoning for Key Stage 2 or 3.
The downloadable booklet will enable you to instant demonstrate some truly baffling mathematical magic addition.

Imagine hearing this:
3769 + 7972 + 4386 + 8257
…and instantly knowing the answer.

You use a selection of *Squashy Boxes* to create a series of random numbers. Your audience can use a calculator to add the numbers together, or work on paper… it doesn’t matter what they use – you already have the answer!

In fact you can write the answer down the instant you see (or hear) the four random numbers!

The download is a beautifully illustrated, 7-page file detailing the complete workings of the ‘trick’. The file includes all of the resources you need and a number of additional ideas and tips.

The magic trickery can easily be adapted so you can perform the same mathematical-magic with 2-digit or 3-digit numbers too.
