1. Week 7 IT 24 Morphemes which add a ‘number’ meaning This teacher led activity aims to introduce children to prefixes which carry a meaning related to number. At the start of the presentation, pictures of cycles appear with different numbers of wheels, and these are linked with the prefixes ‘uni’ ‘bi’ and ‘tri’. Teachers will need to give an explanation to go alongside this, to explain that some beginnings of words give a clue about number e.g. triangle means 3 sided. The answer sheet (see next slide) needs to be printed off and given to the children prior to the lesson. Further ‘number’ morpheme words are given, and children are asked to write ‘how many’ is meant by the prefix each time. This is prompted by the appearance of a pencil. Children are asked what gave them the clue for this number and feedback is then given on screen of the prefix and it’s number meaning, and a picture of the word appears e.g. ‘unicorn’, ‘tripod’.
