A Knowledge Organiser is a go-to document for a topic/unit of work: each one identifies the key information that children need to have learned by the end of a topic. It also acts as a tool to support children in retaining and retrieving knowledge for life-long learning.
Being unable to retrieve knowledge is often a barrier to learning and can become a limiting factor. A child that can't recall the particle structure of states of matter (primary science) is unlikely to understand the concept of measuring density at KS3. Learners need to remember lots of things, for a long time and be able to retrieve this for future learning.
For that reason, we have developed our own Knowledge Organisers to support the delivery of the curriculum, with each one starting with knowledge children should already know from previous learning. Each organiser also has a quiz to help children recall the knowledge and a list of technical vocabulary with definitions.
