Common misconception
Children may think that a metre and a centimetre are similar in length, due to the way they are presented in images that are not to scale.
Allow children to explore practically and develop a sense of the length of one centimetre and one metre. Find familiar items to reference specific lengths e.g. our classroom door is about one metre wide.
