Dig deeper! Join Wobmat the wombat explorer and his friends on 25 maths adventures along the Forest Trail.

The Wobmat Math Challenge is a puzzle series for curious children who love a challenge. Every adventure is a 20-question contest in the multiple-choice style of international primary maths competitions: 7 warm-ups (3 points), 7 trickier puzzles (4 points) and 6 brain-stretchers (5 points).

Inside Book 1:

• 500 brand-new puzzles, all different, with five answer choices each

• Logic, number sense, patterns, shapes and area, cubes and nets, counting, time, money and more

• 224 puzzles with pictures: cube buildings, dice, paper folding, clocks, maps, number walls

• A short, child-friendly solution for every puzzle

• Answer sheet, progress tracker and Bronze, Silver and Gold Explorer badges

Book 1 is the gentlest start in the series. The four Explorer books climb step by step, so a child can grow from their first contest puzzle to the hardest questions for grades 3–4.

Great for maths-contest practice, gifted-and-talented enrichment, maths clubs and holiday brain training. No calculator needed — just a pencil and some patience.

Companion series: Dig Deeper with Wobmat teaches the ideas behind these puzzles in full-colour comic Guides with matching Practice books (Grades 3–4).
