This Content Descriptor from Year 3 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.

identify angles as measures of turn and compare angles with right angles in everyday situations

Elaborations

• 1 using quarter, half and three-quarter turns and comparing them to a right angle; for example, a quarter turn is the same as a right angle; a half a turn is greater than a right angle and is the same as \(2\) right angles; a three-quarter turn is greater than a right angle and is the same as \(3\) right angles
• 2 recognising that right angles occur at the corners of many everyday objects; for example, books, windows, table tops and whiteboards
• 3 identifying angles that are bigger than, smaller than and the same as a right angle in the environment; for example, opening doors partially and fully and comparing the angles created to a right angle
• 4 exploring First Nations Australian children’s instructive games to investigate angles as measures of turn; for example, the game Waayin from the Datiwuy People in the northern part of the Northern Territory
