Numeracy Ideas Involved:
Sharing strategies is a way to learn about new ways to calculate. Most calculation carried out by adults is either done in their head or on a calculator.
Recording supports strategies in lots of ways:
It helps to park information so it does not have to be stored in your memory. You have more brain space left to work with.
It helps you to see how the numbers can be split up and put together.
It helps you to see that situations which look different are the same.
Using materials supports learning in several ways:
It helps you see what actually works with numbers.
It shows you what doesn't work as well.
It gives you an image that you can use when the materials aren't there.
It helps you see how big the numbers really are.
