“The digit tells you how many. The place tells you how much each one is worth.”

What you’ll learn in Digi's Time Quest

Learn how clocks, minutes, hours, days, months and seasons fit together through interactive challenges with Digi.

“The short hand tells you which hour you’re in. The long hand tells you how many minutes have passed.”
Digi's Time Quest on a laptop and a tablet: a boss challenge asks what time an analogue clock shows, and the year wheel shows June in summer.

What you’ll learn in Digi's Estimation Quest

A free rounding and estimation game: round to the nearest 10, 100 and 1,000 on a number line, learn the halfway rule, choose sensible estimates and check calculations — with Digi and Pip.

“Find the two landmarks. Check which is closer. Exactly halfway rounds up.”
Digi's Estimation Quest on a laptop and a tablet: Pip's Hundreds Spring Launcher sends 347 along a number line to 300, and the Estimate-O-Meter shows a sensible estimate.
  • 01

    Landmarks

    Find the two tens, hundreds or thousands either side of any number.

  • 02

    Nearest 10

    Pip's Bubble-Blower floats 32 to 30 and 36 to 40.

  • 03

    The halfway rule

    Exactly halfway — like 35, 350 or 4,500 — rounds up.

  • 04

    Nearest 100 & 1,000

    The same idea at bigger scales: 347 → 300, 2,780 → 3,000.

  • 05

    Sensible estimates

    487 pupils is “about 500” — and why that's useful.

  • 06

    Estimate, then check

    347 + 586 ≈ 900, so 933 makes sense — and 1,533 doesn't.

How Digi’s games work

Build it, see it, then write it

Every idea starts with something to move — blocks to build, clock hands to turn, a year wheel to spin — then a picture, and only then the numbers and words.

Mistakes become lessons

Digi never says “wrong”. A wrong answer shows what the child was thinking, and a short animation explains exactly that idea before trying again.

Ten worlds, step by step

Each game is a ten-world adventure that grows slowly in difficulty, with earlier ideas coming back for practice along the way.

Progress for grown-ups

A parent area in each game shows which skills are strong and which need practice. Progress is saved only on your device.
