Maths Library Australia Year 4 Year 4 maths, age 9 to 10 In Year 4, Australian students consolidate place value to tens of thousands, recall multiplication facts up to 10 × 10, and begin working with decimal representations of tenths and hundredths. They solve multi-step problems involving the four operations, compare fractions, and calculate perimeter and area of regular and irregular shapes. They also study angles, transformations on a grid, and interpret diverse data displays and simple probability.
