Money Maths
Adding up what things cost, working out the change, and buying several of something — starting with coins and building to real shopping amounts. Pick the money you actually use before you start.

This activity is for learning and practice. Anything it suggests is indicative only — it is not a formal assessment and not a substitute for a teacher or tutor.
Nothing you answer is sent to Zerdly. Progress is saved on this device only if you switch saving on, and you can delete it at any time. How Kids Maths handles data.
Set your country and age — change
Setting an age keeps the questions at the right level for that age. It does not lock anything — you can still try any topic, at any age, in any order. Levels are a guide only, not a curriculum.
Your age is not saved anywhere. Your country is remembered only if you have switched saving on.
Saving your progress
Nothing is being saved. You can practise as much as you like — when you close the tab, the session is gone.
Getting the most from it
- Money always has two decimal places. $4.30 is never written $4.3. Get that right and you will get it right on a receipt, a price tag and a calculator — so a one-decimal answer here says “right amount, now write it as money” rather than marking you wrong.
- Count up to find change. Getting from $6.45 to the next whole dollar and then on to $10 is far easier than borrowing across columns, and it is what people actually do at a till.
- The cents are just another column. Once the cents pass 100 that is one whole dollar carried across — the same carrying you already know, wearing a decimal point.
About the currency choice
You pick your currency from the list. Zerdly does not look up where you are — there is no location check anywhere in Kids Maths, and a test blocks one from being added. Each currency here divides into a hundred, so the sums are the same whichever you choose; only the symbol and the words change.
School levels
School levels are a guide only. They show where a skill is usually taught in each country and are not taken from, aligned to, or endorsed by any curriculum authority. Your school may cover it earlier or later.
