I have used this in the past as a great maths starter where I pick a student and challenge the rest of the class that I can get pupil X to be able to multiply two digit numbers faster than they can all do it on their maths calculator. You will find the class will be up for the maths challenge!!!

Below is a great Maths video explaining this Magical Maths trick.

Take the student outside with a mini maths whiteboard and show them a few maths examples. Bring them back in to go against the class on their maths calculators!

A Maths example

11 x 14 = ….

1 ____ 4 (Split the two digit with a blank space in the middle)

1+4 = 5 (Add the two digits together)

1 5 4 (Place the addition total in the blank space)

11 x 14 = 154 (You have your answer)

Another maths example…

11 x 43

4 ____3

4 + 3 = 7

4 7 3

11 x 43 = 473

A tougher maths example

11 x 92

9 ____ 2

9 + 2 = 11

9 11 2 (Add the 1 tens to the 9)

Surely easier to say multiply by 10 and add the number? Like converting kgs to lbs when their are 2.2 lbs to a kg – double it and ad a 10th of the result. eg 130 kg double 260 and a tenth of 260 –> 286lbs.
