Master Key Stage 2 Maths Problem Solving is an essential tool for learning math at home, designed by Carol Vorderman. This 10-minute-a-day task offers activities that teach children aged 9-11 problem-solving skills in an easy and enjoyable way. The activities include fractions, negative numbers, and ratios, making them ideal for reinforcing their math knowledge. The parent section provides answers, explains common mistakes, and offers guidance to avoid them. The 10 Minutes a Day volumes are the perfect reinforcement for lessons taught at school and support the National Curriculum.
