Develop a life habit with this Year 2 Find Change extension. We've all been to the shop and checked our change afterwards, and now your Year 2 children can too (check the change, that is - we don't advise going to the shop without an adult..!) This extension will challenge those who understand the concept further and can be used in class, individually or to promote discussion using mathematical language through collaborative working. It has been designed to have a problem-solving aspect so that children can work systematically.
