4b In new contexts apply their own strategies to solving problems
4b Recognise how a method can be applied to solve similar problems
4b When having difficulty can stop, think about it and approach it in a different way
4a Begin to identify and obtain the necessary information to carry through tasks and solve mathematical problems
5c Break down complex problems, with support, into smaller steps before attempting
5b To carry through tasks and solve problems, identify and obtain necessary information to solve problems
5b Check their results to see if these are reasonable (without prompting)

3c Explain what has been done orally and, where appropriate, using language such as “It must be because.....”
3b Explain thinking behind choices that have been made using language such as “It can’t be because.....”
3a Respond to probing questions giving reasons why choices have been made e.g. “Why do you think that?”
4c Usually present information and results in a clear and organised way
4b Begin to ask probing questions of their own
4b Compare different methods and describe their features
4b Always present information and results in a clear and organised way using lists and tables as appropriate
4a Compare ways of presenting something and say which is better and why
5c Make choices when presenting something and justify why a method is effective
5b Show understanding of a situation by describing them mathematically using symbols, words and diagrams e.g. Bar models (without prompting)
5b Tabulate findings systematically (without prompting)

3c Suggest extensions by asking “What if.......?” or “What could I try next?” type questions
