Using the Nrich Chocolate fraction investigation as a stimulus, this resource is designed to structure an investigation focused on exploring fractions. It involves children making decisions about how six bars of chocolate, spilt unequally over three tables, should be shared equally between a class of 24. However, the investigation states that the children can only enter the classroom one by one which means they have to make a decision as to which table they will choose to receive the biggest equal share of chocolate! This resource pack includes an animated PPT, two tasks, lesson plan, extension reasoning task and solution. The resource is an excellent lesson to use an exploration or assessment task related to fractions and making mathematical decisions. It was created for a job interview lesson observation which was graded as outstanding; perfect for anyone needing support for a lesson observation or interview observation.
