Place Value Quest in the Classroom
Last updated:
Why it fits a classroom
- Free, with no subscription and no paid tier.
- No student accounts and no personal data — open it in a browser and play. See the privacy policy.
- Works on an interactive whiteboard: everything is tap, drag and choose, with large targets and no typing.
- Visual representations the whole class can discuss — blocks, place-value boards, counters and number lines on the same screen.
Ways to use it
- Five-minute warm-up. Put the Digit Machine or a “which is correct?” question on the board and ask the class to vote before you tap.
- Stations or centres. One device per pair; each pair works through a world and explains its answers to the other.
- Targeted support. Pupils who stumble on zeros or on thousands can practise exactly that — the game adapts its questions to the skills a child finds hardest.
What it covers
- Ones Village — numbers are built; 10 ones make 1 ten
- Tens Forest — tens and ones, and trading
- Hundreds Castle — 10 tens make 1 hundred
- Digit Factory — a digit’s position sets its value
- Zero Caverns — three-digit numbers and zero as a place holder
- Thousands City — 10 hundreds make 1 thousand
- Trading Station — four-digit numbers and their zeros
- Space Station — ten thousands and beyond
- Number Vault — reasoning from clues
- Number Kingdom — everything together, up to six digits

Digi’s Time Quest in the classroom
The same fit applies to Digi’s second game: free, no student accounts, and friendly on an interactive whiteboard. A large analogue clock with draggable hands makes whole-class questions easy — “where should the hour hand be at half past 3?” — and the game’s common mix-ups (reading the nearest hour, the minute hand as minutes, quarter to as quarter past) make good discussion starters.
What it covers
- Sunrise Meadow — what is time: order, before and after, duration
- Tick-Tock Workshop — seconds, minutes and hours
- Clocktower Town — the hour hand and the minute hand
- Quarter Gardens — o’clock, half past and quarter past
- Quarter Harbour — quarter to
- Minute Mountains — the five-minute scale
- Timeline Railway — elapsed time
- Calendar City — days, weeks, months and years
- Season Islands — seasons and why they happen
- Crystal Observatory — everything together
It covers concepts commonly taught around ages 8–10. It is not tied to or certified against any particular curriculum. For background, see how to tell the time.
