Market Day

Your child plans community events on a budget: a class picnic, a library reading day, a park clean-up. Each event has a goal, a fixed budget and a list of needs, and often more than one plan is right.

How it plays

What your child does

  1. Compare two to five choices and build a plan with + and − buttons.
  2. Press Check plan. If something is missing, the game names one thing at a time: “Your plan has 10 snacks. We need at least 20.”
  3. The plan stays as it was so your child can fix it. After two tries, Show a plan that works appears.
  4. Event Planner is free play: pick an event, the guests and a budget, then plan.

Five sets

Make a Plan

Meet every need inside the budget.

Compare Choices

Pack sizes, how long things last and waste. The cheapest is not always best.

Stock the Stall

Read last time’s graph, then bring about the right amount.

Change of Plans

More guests, a missing item or a smaller budget: revise the plan.

Community Goals

Needs and wants, and planning so everyone can join in.

For grown-ups

Good to know

  • Money left over and speed never add stars, and spending the whole budget is never the goal.
  • No real shops, brands, purchases, debt or investing, and the game never asks about your family’s money.
  • Everything works by tapping; nothing needs dragging.
  • The home screen shows Market Day to children aged 8 to 10. You can turn it on for any child in the Parent Zone.
  • The game saves itself, so your child can stop at any time and pick up where they left off.
