Describes mathematical situations and methods using everyday and some mathematical language, actions, materials, diagrams and symbols
Uses objects, diagrams and technology to explore mathematical problems
Supports conclusions by explaining or demonstrating how answers were obtained
Uses a range of strategies and informal recording methods for addition and subtraction involving one- and two-digit numbers
Represents and models halves, quarters and eighths
Uses a range of mental strategies and concrete materials for multiplication and division
Applies place value, informally, to count, order, read and represent two- and three-digit numbers
Uses number bonds and the relationship between addition and subtraction to solve problems involving partitioning
Uses the structure of equal groups to solve multiplication problems, and shares or groups to solve division problems
Applies an understanding of place value and the role of zero to read, write and order two- and three-digit numbers
Use mathematical modelling to solve practical problems involving additive situations, including simple money transactions; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem
