About Market Day
Market Day turns 11+ money, decimals, units and time questions into a day on a market stall. Fifteen orders arrive between the morning bell and closing time, and each one is a question. Each part of the day leans on different topics, from money and time in the morning to decimals and units in the afternoon, and every day covers all five.
Right answers fill the till and raise your reputation, and as more orders are served the stall gets upgrades, from a striped awning to a golden sign. The last order of the day is a big order: a harder question for triple takings. Questions get harder after a streak and easier after misses. Reputation sets the star rating at closing time, and the stall review explains every trap that sent a basket away.
How to play Market Day
- Choose your role (Saturday Helper, Stallholder or Market Champion) and press Open the stall.
- Read the order ticket on each basket, then tap the right answer to serve it.
- Answer quickly to earn a tip on top of the order’s price.
- Get three right in a row to start rush hour, when every order pays double.
- Serve the big order at the closing bell for triple takings, then see your star rating.
What it practises for the 11+
- Money
- Questions ask for change, totals, best buys, special offers and sharing a bill, often read from a price list. It builds careful working with pounds and pence, e.g. the change from £5 for £3.65 is £1.35. Learn the topic →
- Decimals: Addition and Subtraction
- Questions ask children to add and subtract decimals, make up a whole, fill in missing digits and solve problems in mixed units. It builds the habit of lining up the decimal points, e.g. 4.5 + 2.75 = 7.25. Learn the topic →
- Decimals: Multiplication and Division
- Questions ask children to multiply and divide decimals, use a fact they already know and work out the cost of one item. It builds a sense of where the decimal point goes, e.g. 0.4 × 3 = 1.2, so 0.4 × 30 = 12. Learn the topic →
- Units
- Questions ask children to convert between metric units, read scales, compare measures, and use imperial equivalents and exchange rates. It builds a feel for how big each unit is, e.g. 2.4 litres is 2,400 ml. Learn the topic →
- Time
- Questions ask children to read clocks, change between 12-hour and 24-hour times, work out how long things take and read timetables and calendars. It builds careful counting on, e.g. from 9:45 to 11:20 is 1 hour 35 minutes. Learn the topic →
Try Market Day questions
Questions from the game, for you to try together. Have a go before opening the answer.
Question 1 · Money
Theo buys a book for £4.45 and pays with a £5 note. How much change should Theo receive?
- £0.54
- £0.55
- £0.65
- £1.55
- £9.45
Show the answer
£0.55 — Count up from £4.45 to £5: the change is 55p.
Question 2 · Decimals: Multiplication and Division
One battery costs £8.65. How much do 4 batteries cost?
- £32.40
- £12.65
- £346.00
- £34.60
- £32.65
Show the answer
£34.60 — Multiply: £8.65 × 4. Ignore the point: 865 × 4 = 3460. £8.65 has 2 decimal places, so the answer has 2: £34.60. Check: about 9 × 4 = 36.
Question 3 · Time
What is twenty to six in the afternoon on the 24-hour clock?
- 17:40
- 15:40
- 18:40
- 05:40
- 17:20
Show the answer
17:40 — Twenty to six in the afternoon is 5:40 pm: add 12 to the hours for pm (5 + 12 = 17), so 17:40.
