National numeracy skills are low, with almost 17 million adults lacking skills for the lowest GCSE grade and 65% of adult prisoners at an 11-year-old level or below. Students with low numeracy are twice as likely to be unemployed. Miss B's Resources provides various activities teachers can use to improve students' numeracy, such as impact lines focusing on number sense, battle words applying coordinate knowledge, and a thermometer of understanding activity rating learning more accurately than simple traffic light systems. The resources aim to incorporate numeracy development into different lessons to help overcome beliefs that maths can't be improved.
