A sorting activity on angles for Year 3 maths. Pupils place everyday exhibits, from the corner of a square to clock hands at 3:00 and a wide open laptop, into three display cases: less than, exactly, or greater than a right angle. Two follow-up questions ask which item was hardest to place and for new exhibits of their own. Answer key included. Matches two England National Curriculum angle objectives.
Geometry — properties of shapes
“Identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle”
The three display cases are the greater than, less than and equal comparisons.
Geometry — properties of shapes
“Recognise angles as a property of shape or a description of a turn”
Exhibits mix shape corners with turning objects like clock hands.
Everyday angle examples such as the corner of a square, a letter V and clock hands at 3:00.
Write each exhibit into the right case: less than, exactly, or greater than a right angle.
Say which item was hardest to place, then invent a new exhibit for each case.
Correct sorting plus example answers for the open questions.
Paired sorting
Pairs debating where each exhibit belongs generates useful angle talk.
Lesson plenary
The hardest-to-place question makes a natural closing discussion.
Homework
Adding new exhibits sends pupils angle-hunting around the house.
