If your pupils have been learning about halves, we have the ideal challenge to extend their knowledge! This Year 2 Recognise a Half Discussion Problem worksheet requires children to travel through a maze by crossing different representations of a half. Designed to encourage children to work in pairs or small groups, this extension challenge will promote problem solving and reasoning skills, whilst deepening children's understanding of halves. There are multiple answers to this challenge, but we have included a sample answer as an example.
