Pupils describe their approach in a well functioning way, and apply well developed and well informed reasoning about the plausibility of results in relation to the problem situation, and can make proposals on alternative approaches.
Pupils can solve simple problems in familiar situations in a well functioning way by choosing and using strategies and methods with good adaptation to the type of problem.
Pupils have very good knowledge of mathematical concepts and show this by using them in new contexts in a well functioning way.
In the descriptions, pupils can switch between different forms of expression and also apply well developed reasoning over how the concepts relate to .
Pupils can also describe different concepts using mathematical forms of expression in a well functioning way.
Pupils can choose and apply appropriate and effective mathematical methods with good adaptation to the context to carry out simple calculations, and solve simple routine tasks in arithmetic, algebra, geometry, probability, statistics, and also relationships and change with very good results.
Pupils can account for and discuss their approaches in an appropriate and effective way and use diagrams, symbols, tables, graphs and other mathemati cal forms of expression with good adaptation to the context.
In their accounts and discussions, pupils can apply and follow mathematical reasoning by putting questions, putting forward and responding to mathematical arguments in a way which takes the reasoning forward and deepens or broadens them.
