Here is a brief summary of some of the most important maths concepts and ideas to be taught in Year 3. For a more detailed account go to the Further Resources category, under, 'What is expected?' 1. Choosing appropriate number operations An important aspect of Using and Applying Maths is concerned with children choosing and using the most appropriate number operations to answer questions and solve problems. 2. Open and closed questions Solving problems and investigating continue in three year. Some of these problems are ‘closed’, in other words they only have one, or a few possible answers. Others are ‘open’ and can have many possible answers. 3. Working in a systematic way A key feature of this work is that children should become more systematic in their approach, checking as they go and looking for answers which are the same. They should be able to talk about their work, especially about how they are tackling the investigation, what the rules are and any findings they have. 4.  Solving problems In year 3 children are expected to use any of the four operations to solve ‘story’ problems.
