An outdoor math walk is mathematics without a workbook — counting, measuring and shapes done with the hands instead of a pencil. And here is the surprise: for the youngest children, math often sticks better on a forest trail than at the kitchen table. Why? What turns an ordinary walk into a math lesson, without the child ever noticing they are "practising"? The answer is hidden in how the brain actually learns number. Let us dig it out, one step at a time.
In short: An outdoor math walk uses nature as the workbook — the child counts trees, measures distances in footsteps, finds shapes in stones and makes patterns with pinecones. It all trains the same core ideas LK20 asks for, but the child feels the math with the body first, so the numbers stick better later.
What is an outdoor math walk?
An outdoor math walk lets nature be the exercise book. Instead of filling in rows of numbers, the child counts what actually lies along the trail: how many bridges you cross, how many red things you pass, how many steps it is to the big tree. The math is the same — it just comes dressed for the outdoors.
And here is what surprises most grown-ups: mathematics does not begin with numbers. It begins with comparing. Long before a child can write the number 7, they can see which of two stones is bigger, which stick is longer, which bucket is heavier. That is real math — quantity, size and measurement — done with the body, not with symbols. To see why this kind of hands-on exploration is the heart of children's STEAM, the whole idea lives in what STEAM learning really is.
Why does this matter for children?
Children learn math from the ground up: first with the body, then with pictures, finally with numbers. LK20 knows this. In the mathematics curriculum the word "explore" sits at the centre from Year 1: children should explore numbers, quantities and counting in play and nature, and measure and compare sizes with their own body units before they meet the centimetre. A walk in the woods is not a break from the curriculum — it is the curriculum, just without the desk.
The best part for you as a grown-up is that you do not need to be good at math yourself. You only need to ask the question and let the child guess first: "How many steps do you think it is over there?" That short pause is where the math takes root.
Try it at home: the math walk
Take the child on an ordinary walk and add four stops: count something the whole way, measure the distance to a tree in footsteps (guess first), hunt for shapes — a circle, a triangle, a rectangle — and sort five pinecones from smallest to largest. For more all-summer ideas, see outdoor learning by LK20 and the math hidden in nature.
Then the important bit: what happens if you measure the same stretch with the child's steps and then with yours? Do not give the answer — let the child discover the difference.
Every child is made of good atoms — and some of them count, measure and wonder best out in the world.
