Ahoy, me hearties! Captain Violet and Polly the parrot have lost their treasure, and only your kids can find it.

In this pack, Year 2 kids learn to add and subtract 2-digit numbers by splitting them into tens and ones and jumping along number lines. Then they put it into practice by solving sums to crack three secret codes. A wrong answer gives the wrong letter, so kids can spot and fix their own mistakes! The codes lead to a treasure trail map, and pirate word problems finish the adventure.
