- Year 4 teacher Josie Clark has taught negative numbers in the past using analogies like bank accounts or thermometers. Some children have been confused or found it difficult to transfer the idea.Today she's using very specific language to establish the difference between one and negative one. She extends this language and is getting the children to write carefully on the page to establish the difference between the negative number sign and the act of subtracting.The mental starter gets the children to practise the new language of negative and subtract . A story establishes that negative is the lack of something, in this case a pile of sand. Children demonstrate, moving cards helps them visualise the actions of adding, subtracting and dividing negative numbers. In groups, the children successfully divide and the camera dwells on a group that need support to successfully multiply.Maths adviser Richard Dunne is on hand with hints and tips.
Year 4 high flyer Anthony, and Blue, who has to work at literacy, invite us to share their learning about negative numbers. They find out about zero and how it can be substituted as a one and negative one together to make some calculations easier. The teacher uses a story to establish how one and negative one together make zero, and reinforces this with Anthony as demonstrator.We follow Blue's group for 3 subtract negative 2 . They use their knowledge that zero has the same value but difference appearance when it's shown as 1 and negative 1 together.Anthony makes a confident start in his head, but gets some calculations wrong, revealing frequent misconceptions. The teacher encourages him to use cards and he is successful, but he tells us of his upset at not being able to do the calculations mentally.Blue and Anthony's honest reflections will help many teachers understand what goes through children's heads as they introduce this confusing area of maths.
