Guide 4AThe Logic Lagoon

A holiday at the lagoon turns into a mystery. Crack logic puzzles, count every possibility at the beach games and turn animal surveys into charts.

In Dig Deeper with Wobmat, Wobmat the wombat explorer and his friends Pippa, Kip, Nora and the cheeky magpie Mags don't just show you the answer: they get stuck, argue, try things and discover the maths together, in full-colour comic lessons.
