2.4 Response and level guidance: Addition and Subtraction Assessment
The document below is specific to the addition and subtraction assessment and provides:
- The answers to the questions in the addition and subtraction assessment.
- Examples of the most common strategies pupils are likely to use and the names of these strategies. This is to help those delivering the assessment make sense of strategies that they may not be familiar with.
It is also useful from a professional development point of view to explore the strategies described to develop a greater awareness of the types of strategies that individuals might use and also reflect on their effectiveness and efficiency.
Be aware that some pupils may use strategies not listed or use a combination of one or more strategy.
- Guidance as to the approximate level that a strategy is at.
It is not easy to say that a pupil is at e.g. First *** or Second * as a result of one question or one strategy. The stage is decided upon based on more of an overview of the combination of strategies, the efficiency and the number range they are working within.
Use the guidance particularly if you are unsure what level to place a pupil at or if you are unfamiliar with the range of addition and subtraction strategies.
Before you look at the document, have a go at the assessment questions yourself thinking about how you would solve the problems mentally. You may wish to do this as a group (comparing strategies) or individually.
Read the guidance document and see which strategy you used and consider what the advantages/disadvantages are of your strategy compared to the other strategies.
