Mission 11
The Market Challenge
Saturday is market day. Fill a birthday fruit bowl, shop a neighbor's list, mind the fruit stall, stock a club stall and run a juice bar. Every job takes coins, and a coin can be spent well or spent better. Count, weigh, compare, and choose.

For grown-ups: what this mission practices
Comparing more and fewer and counting coins out to a price; comparing prices and tracking a purse; weighing in kilograms, pricing by the kilogram, adding a bill and giving change; unit prices by the item, kilogram and liter, and when the big pack is not the better buy; setting a price that covers costs; and weighing quality, quantity and price inside a fixed budget, then justifying the choice.
- Ages
- Five versions, from Preschool to Grade 8. They are different designs, not the same task with other numbers.
- How it is checked
- Every answer is checked by rules the child can see at work on the screen. Any answer that meets them is right.
- Help
- Olly can read any line aloud, give a hint that points at where to look, or show one way. A report says where help was used.
- Time
- Nothing is timed. A part takes a few minutes and progress is saved after each one for a signed-in child.
