Knowledge organisers include the key information and vocabulary that are required to fully understand a topic. The information in the knowledge organisers are the minimum that should be known, rehearsed and, ultimately, remembered. It is a given that plenty of other technical vocabulary and facts will be encountered and learnt throughout the topic.
Pupils will benefit from learning some of this material ahead of time – by having an initial grounding in a topic, children will enter lessons more able to participate and will be more able to make links to prior learning.
