How does a teacher assess progress? Aston Tower, Birmingham, serves the inner city. The year 2 teachers are anxious about how they can accurately build up a picture of children’s skills at the end of KS1. They’ve worked with Maths consultant Val Worcester to design active assessment opportunities. In shape, Melanie works with a whole class. Each has a shape fan so they can make a visual response to the class puppet’s (Melanie’s) questions. She encourages discussion with a smaller number of focus children. In money, Vanessa works with a small group on an activity inspired by ‘The Great Pet Sale’. They use real coins to pay for the pets, adding the coin values together in pairs. In calculation, a group is throwing bean bags at printed numbers. They add the numbers mentally or with the support of resources they must choose for themselves. In capacity, celebrating Eid has presented a challenge. The children use water to find out how much juice they need to fill 30 party cups. We see how teachers assess progress.
