Practising mental maths is key to children's mathematical development and this book provides a quick and simply way of delivering a maths test on every day of the school year. There are 190 tests in total, each with ten questions: Warm up questions, Quick fire questions and a Problem solver to really get brains ticking. All the questions are read out on the accompanying audio CD so all the pain is taken out of delivering mental maths! The tests get progressively harder throughout the book but in small steps so that most children will get most of the answers right most of the time. All answers are provided at the back of the book for easy checking by the pupil or teacher.
