Common misconception
Pupils create bar models where the parts do not equal the whole or vice versa.
Whilst this may be a calculation error, it is important that the context of the story is considered when looking to re-adjust the bar model. Take time to work through the context again building the bar model from the what is known.
A sign of pupils depth of understanding can often be indicated by their creating their own examples. Encourage pupils to come up with multiple different contexts for each bar model and share these with their peers to continue to make links beyond their own personal experiences.
