Maths Library Australia Year 1 Year 1 maths, age 6 to 7 In Year 1, students develop two-digit place value understanding to 100, partition numbers, and recall basic addition and subtraction combinations. They explore repeated addition using arrays, recognise halves of shapes and collections, and create number patterns. Measurement work includes reading analogue time to the half-hour, recognising Australian coins, and collecting data into simple tally displays.
