How many people do you think are in this stadium?
Make an estimate before you read on.
Maybe you looked at the picture and thought there were around 5,000.
Maybe you went higher. Maybe lower.
Maybe you worked from roughly how many people you could see in one section and then scaled it up.
There isn't one particular way I want you to do this.
What I'm interested in is how you estimated it.
Because that's actually a really important part of maths.
Estimation isn't just about getting close to the right answer. It's about developing a feel for numbers.
It's being able to look at something and think "that seems about right" or "hang on, that's way off."
And that's a really useful skill for children to develop as the maths gets harder.
Because when they're working with much bigger numbers, decimals, percentages or calculations with several steps, having a sense of what the answer should look like, or what it definitely shouldn't be, gives them something to check against.
So the next time you're out somewhere, have a go.
How many people are there?
How much do you think that shopping will cost?
How long do you think the journey will take?
You don't need to turn it into a maths lesson.
Just ask for the estimate.
That's where a really interesting conversation often starts.
