Acute and Obtuse Angles Worksheet | Compare and Order Angles | Year 4 Maths

Help Year 4 pupils identify acute, right and obtuse angles and compare and order angles by size, with 30 questions, clock hands and angles in shapes in this print-and-go maths pack.

Pupils sort twelve angles drawn in different positions as acute, right angle or obtuse, circle the bigger angle in four pairs (including a pair with different arm lengths), put three sets of three angles in order of size and use the hands of six clocks to decide whether the angle is acute, right or obtuse. They also count the acute, right and obtuse angles in a triangle, a trapezium, a parallelogram and a hexagon, answer true or false statements, draw an acute and an obtuse angle and explain why Tom is wrong about arm length. The front page includes a cut-out right-angle checker. This supports the Year 4 geometry statement in the National curriculum in England: “identify acute and obtuse angles and compare and order angles up to two right angles by size”.

What is included (5 A4 pages plus a thank-you page):
• Page 1: an overview with “I can” statements, the curriculum link, the types of angle and a right-angle checker.
• Page 2: Name the Angle. Twelve angles to sort (Q1–12).
• Page 3: Compare and Order. Pairs, order of size and clock hands (Q13–25).
• Page 4: Angle Puzzles. Angles in shapes, true or false, drawing and reasoning (Q26–30).
• Page 5: the answer key for all 30 questions, with the alternative answers for Q28 and Q30 listed.
• Page 6: a thank-you page.

Great for: a maths starter, homework, revision, cover work or a quick check of understanding after teaching angles.
