2, 5 and 10 times tables
The first three tables and their super-powers: doubling, half of 10, tens.
🗺️ ① The treasure map
Each island hides the secret of a times table. Discover it, practise by playing, then take the challenge to conquer the island. Islands open one after another.
🎯 ② Today's mission
The tables of your conquered islands come back a little every day, at just the right moment, so you never forget them.
Today's mission: a dozen questions, about 5 minutes.
Without child mode you can try it, but your progress is not saved.
🔢 ③ My treasure grid
🦸 ④ My superpower cards
One card for each conquered island.
Step 1
× 2: doubling
Multiplying by 2 means adding the number to itself.
4 × 2 is double 4: 4 + 4 = 8.
Step 2
× 10: tens
Ones become tens: 4 × 10 is 4 tens.
4 × 10: 4 ones become 4 tens, that is 40.
Step 3
× 5: half of × 10
Work out × 10, then halve it. The answers always end in 0 or 5.
4 × 10 = 40, and half of 40 is 20.
