The £10 Birthday Budget: a 20-minute lesson in choosing

An activity for ages 9-11. Give your child an imaginary £10 and a wish list that costs more, then watch them discover what budgeting actually feels like.

✏️ Paper and pen

Budgeting sounds abstract until there isn’t enough money. This activity creates that moment safely, with imaginary money, so the first time your child feels the pinch of choosing isn’t with real cash they’ve saved for months.

What you need
A sheet of paper, a pen, and ten minutes of your child’s attention.

How it works

  1. Set the scene. “Imagine it’s your birthday and someone gave you £10. It’s yours. What would you spend it on?”
  2. Write the wish list together. Five or six things they’d genuinely like, with a rough price beside each. Be generous with the list — you want it to add up to more than £10. Around £20 works well.
  3. Add it up. Let them do the addition. When the total lands above £10, don’t say anything. Wait.
  4. Ask what they’ll do. Not “what will you cut” — just “so what happens now?” Some children cut items. Some look for cheaper versions. Some ask whether they could wait and save. All three are correct.
  5. Get to a final list that fits. They cross things out until the total is £10 or under. That crossing-out is the entire lesson.
  6. Ask the good question at the end. “Was anything harder to give up than you expected?” This is where children notice what they actually value, which is usually a surprise to them.
What they’re learning

That a budget isn’t a rule imposed by someone else — it’s the arithmetic of wanting more than you can have, and choosing on purpose rather than by accident.

What usually happens

Children often try to negotiate the £10 upwards. Hold the line kindly — the constraint is the activity. Without it, there’s nothing to learn.

Many will spot that waiting is an option before you mention it. If they do, that’s a genuinely good instinct and worth naming out loud.

Make it easier

Use £5 and three items. Round the prices to whole pounds so the maths stays out of the way.

Make it harder

Add two rules: £2 must be saved, and one item has to be a gift for someone else. Now they’re budgeting with commitments, like an adult.

Budgeting and prioritising run through lessons 2 and 9 of the Smartmonies programme, where children work through the same choices with a teacher. See the ten lessons →
