Brodie and Jai explain their maths activity, Number Scrolls.
They started with two numbers, 81 and 83.
How do you get from 81 to 83? They figured it out using fingers and
thinking, then made a rule on the calculator to create a massively long list of
numbers. 2 + = = =  They even knew how to say all of them!

Why don’t you try to make a number scroll on their numbers? Do you notice any patterns?
