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.

  1. Step 1

    × 2: doubling

    Multiplying by 2 means adding the number to itself.

    4 × 2 is double 4: 4 + 4 = 8.

  2. Step 2

    × 10: tens

    Ones become tens: 4 × 10 is 4 tens.

    4 × 10: 4 ones become 4 tens, that is 40.

  3. 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.
