This Content Descriptor from Year 1 Mathematics provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

Content Descriptor

use mathematical modelling to solve practical problems involving equal sharing and grouping; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem

Elaborations

  • • modelling problems involving repeated equal group situations, such as, “How many wheels are needed for \(3\) cars?”, using materials and drawing a picture to show what they did, and recording the results with a number
  • • modelling practical problems involving equal sharing situations; for example, sharing a set of dominoes between the \(2\) players in a game, and then counting or subitising to ensure they both have the same number of tiles
  • • modelling money problems involving equal sharing; for example, sorting coins from a money box according to their denominations, sharing the coins equally between \(4\) people, and using counting or subitising to ensure they have equal amounts of each denomination

Year 1 ASMATY1
Year 1 Mathematics Achievement Standard
By the end of Year 1, students connect number names, numerals and quantities, and order numbers to at least 120. They demonstrate how one- and two-digit numbers can be partitioned in different ways and that two-digit numbers can be partitioned into tens and ones. Students partition collections into equal groups and skip count in twos, fives or tens to quantify collections to at least 120. They solve problems involving addition and subtraction of numbers to 20 and use mathematical modelling to solve practical problems involving addition, subtraction, equal sharing and grouping, using calculation strategies. Students use numbers, symbols and objects to create skip counting and repeating patterns, identifying the repeating unit.They compare and order objects and events based on the attributes of length, mass, capacity and duration, communicating reasoning. Students measure the length of shapes and objects using uniform informal units. They make, compare and classify shapes and objects using obvious features. Students give and follow directions to move people and objects within a space. They collect and record categorical data, create one-to-one displays, and compare and discuss the data using frequencies.
