Learn arithmetic playfully: children practice shopping, borrowing, lending and saving money. With illustrative coins and bills, age-appropriate tasks for 7–10-year-olds and multiple languages, mathematics becomes tangible in everyday life.

How the games work

First choose your language, then a game and your age group:

• 7–8 years: Calculations with whole euro amounts, addition and subtraction.
• 9–10 years: Also cent amounts, multiplication and division.

Via “🌐 Languages” you can return to the language selection at any time.

🛒 Shopping game

1. Choose the number of items and the desired shopping categories.
2. You will receive a shopping list with item descriptions and hints about the desired quality.
3. Estimate how much money you need and assemble your starting money from coins and bills.
4. Compare the offers: Which item matches your shopping list and the desired quality?
5. After each purchase you solve matching arithmetic tasks.
6. At the end you see your purchases, calculation answers, expenses and remaining money.

🥕 Buying ingredients

1. Choose whether the number of people is determined randomly or you set it yourself.
2. You will receive a dish with a list of ingredients. Quantities and prices are each given per person.
3. Calculate the total quantities needed and the money required. Your chosen amount will be your starting money.
4. Compare the offered quantities, quality levels and prices in the store. Skip items you do not need.
5. Pay with appropriate coins and bills. If you pay more, you will receive change.
6. At the end you will find out which ingredients were bought correctly, what is missing and whether your quantity and money calculations are correct.

For money planning: you may plan up to 30% extra on top of the required amount; the maximum amount is rounded up to whole euros.

💰 Calculating: Borrowing, Lending and Saving

First choose one of the three areas. Then you will receive a story with a starting amount and several action steps.

Borrowing: You receive money from other people and pay it back later. Track how your cash changes with each transfer.

Lending: You give money to other people and get it back later. After each step calculate your current cash balance.

Saving: You receive, for example, pocket money or a gift and spend money in between. Calculate how much you have left after each step.

For each task you assemble your answer using the displayed coins and click “Check answer”. After a wrong answer you get another attempt. Then the correct calculation method is shown. At the end you receive an overview of all steps and your result.
