The monsters enter a sandcastle competition. Scooter has built a machine to help them, but it goes wrong and they have to start again! Cora comes up with an idea of how to impress the judges. Will they win a prize? Stories for Maths helps develop maths mastery through the power of story. This series aligns with the White Rose Maths schemes of learning. Each book has questions at the bottom of the pages and an activity page at the end of the story, which help to draw out that learning by asking questions and encouraging talk about maths. Key maths words and phrases are also highlighted in each book, further helping to deepen understanding and grow children's mathematical skills. The books in Year 1/Primary 2 are designed for an adult to read to a child, although there is some decodable text that children may be able to read themselves. This book aligns with White Rose Maths for Year 1, Addition and subtraction (within 10), Step 1. Introduce parts and wholes, and Step 2. Part-whole model.
