Build two giant calendar wheels and find when their markers line up again.
Two giant wheels turn side by side: one counts 13, one counts 20. When do they line up again? Think big.

What you’ll build
Build two giant calendar wheels side by side, one with numbered markers and one with day symbols you invent. Walk them with a partner one day at a time to find when they line up again, then crack an even bigger cycle and build a lantern plaza.
Finish line: Your two calendar wheels have your own day symbols, the meeting point is found and the lantern plaza glows.
Bonus challenge: Work out your first 'Calendar Round birthday': the day both wheels and the year wheel line up exactly as when you were born. How old will you be?
You’ll need
- Building blocks for two circles
- Lanterns
- A family member to walk with you
You choose
- My calendar's name
- My 20 day symbols (invent your own)
- My bet for days until the wheels match again
Stuck?
- Circle looking lumpy? Mark the four compass points first at the same distance from the centre, then fill between.
- Markers spaced unevenly? Count the rim blocks first and divide by the number of markers.
- Losing count on the walk? Switch to paper and write each pair down.
