Lucky Clover Club and the Maths Monsters

Four friends' ordinary camping trip turns into a monstrous maths adventure... Using your own skills of addition, subtraction, multiplication and division, can you help them solve the tasks and get past the monsters? The story incorporates interactive maths questions to stimulate and help improve children's problem solving skills. The questions cover a few different levels of difficulty, carefully aligned to Key Stage 1 (and a little bit beyond to challenge really keen boys and girls!) in the UK, or suitable up to Grade 3 in the Common Core Standards in the USA.
