Content Descriptor

quantify sets of objects, to at least 120, by partitioning collections into equal groups using number knowledge and skip counting

Elaborations

• counting a large collection of items using groups of fives or tens and skip counting to work out how many there are; recording the amount and connecting the digits in the number to the grouped materials when using groups of $10$
• counting collections of objects such as pencils or images of birds in a tree, by grouping them in tens to enable efficient counting and connecting the digits in the number to the groups of tens and ones
• counting a large collection of Australian $\$1$ coins by stacking them into piles of $10$, skip counting in tens and including any leftover coins to determine the total value

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.
