Maths O'Clock

Built on how children actually learn maths

Every sum is attached to a named strategy, shown fully worked and then faded step by step, mixed rather than blocked, and revisited on a spreading schedule. Mistakes get named, not just marked. No ads, no accounts, nothing leaves the device.

Free maths games for kids: telling the time and mental maths

Maths O'Clock is two small practice games for primary school children, roughly ages five to eleven. They are free, have no adverts and need no sign-up. Each game is played in short sessions of ten questions, with stars for right answers and a daily streak for coming back.

Tick Tock Quest: learn to tell the time

  • Reading an analogue clock: o'clock and half past, then quarter past and quarter to.
  • Minutes past and to: five-minute times like 4:35, then any minute like 9:52.
  • Time in words: matching "twenty past six" to a clock or a digital time.
  • Setting the clock: dragging the hour and minute hands to show a time.
  • Elapsed time, am/pm and the 24-hour clock.

Sums Copybook: mental maths through strategies

  • Times tables: learned through strategies like doubling, "five is half of ten" and "nine is ten take one".
  • Division: as multiplying backwards.
  • Number bonds and adding: pairs that make ten and 100, doubles, bridging through ten.
  • Taking away: counting up, going back through ten, adjusting from ten.
  • Place value and rounding: to the nearest ten and hundred.

Every sum comes with a worked example first. The steps fade as your child gets them right, and strategies are mixed and revisited on a spaced schedule. Read the approach and the research behind it.

Questions from parents and teachers

Is Maths O'Clock free?

Yes. Both games are completely free, with no adverts, no sign-up and no in-app purchases. They are free to use at home and in the classroom.

What age is it for?

Roughly five to eleven, or primary / elementary school. There are no fixed year groups: the maths game places each child with a short first round and moves each strategy on independently, and the clock game runs from o'clock and half past up to 24-hour time.

Does my child need an account?

No. Your child just types a first name. Stars, streaks and progress are saved in the browser on that device only and are never sent anywhere.

Does it work on a tablet or phone?

Yes. It runs in any modern web browser on tablets, phones, laptops, Chromebooks and interactive whiteboards, with nothing to install.

How is this different from a times tables drill?

Every question is attached to a named strategy, such as "nine is ten take one" for the nine times table. The strategy is shown as a worked example first, then the steps fade as your child improves, and different strategies are mixed so your child learns to choose the right one.
