• Transum,
•
• The eleven times table has always been very easy to learn up to 9 x 11. Here's a way of multiplying large numbers by 11 too:
Example:
Q. What is 324 x 11 ?
A. Write down the first digit ... 3
.......Add the first and second digits ... 3 + 2 = 5
.......Add the second and third digits .. 2 + 4 = 6
.......Write down the last digit ........... 4
Try it yourself ... multiply 543 by 11
Do you know why it works?
Does it work for all three digit numbers?

Notes for the teacher:

1. You can drag the numbers in the animation above and they will stop moving. Your pupils may prefer a stationary Starter rather than trying to keep track of the moving numbers.

2. It might be necessary to do the Eleven In Your Head activity first (the link is can also be found further down this page) before pupils are able to see the patterns and appreciate the place value significance.

3. Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated. Click the button below to regenerate another version of this starter with a different word.

## Texas Instruments Nspire Calculator

This handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in the mathematics and science classroom. TI-Nspire technology has been developed through sound classroom research which shows that "linked multiple representation are crucial in development of conceptual understanding and it is feasible only through use of a technology such as TI-Nspire, which provides simultaneous, dynamically linked representations of graphs, equations, data, and verbal explanations, such that a change in one representation is immediately reflected in the others.

For the young people in your life it is a great investment. Bought as a gift for a special occasion but useful for many years to come as the young person turns into an A-level candidate then works their way through university. more...
