Learning about shapes and angles
These Year 4 Maths games practise Acute and obtuse angles, Triangles and quadrilaterals. Choose a game above for a short activity, or explore the examples below before you play. The full guide for each game explains its controls, gives more examples and includes a free printable for practice away from the screen.
Talk it through
Use counters, a drawing or a number line before moving to a mental method. Ask your child to explain a choice, then change one number and try the method again.
Ask: “How could you show the same answer another way?” Give your child time to explain. Return to an example after playing and ask whether they would approach it differently.
Acute and obtuse angles
Year 4 pupils identify acute and obtuse angles and compare and order angles up to two right angles by size.
Try an example: The angle between clock hands at 2 o'clock
Smaller than a right angle.
Show the answer
acute
What to look out for
Mixing up the words acute and obtuse. Acute angles are 'a cute' little angles. Obtuse angles are the wide ones.
Triangles and quadrilaterals
Year 4 pupils compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes.
Try an example: 4 equal sides, but no right angles
Equal sides like a square, but slanted.
Show the answer
rhombus
What to look out for
Thinking a square cannot be a rectangle. A rectangle has 4 right angles. A square has them too, so it is a special rectangle.
Practise away from the screen
- Make angles with arms or with two pencils and name them.
- Look for triangles and quadrilaterals in buildings, bridges and road signs.
Curriculum connections
These games support selected practice connected to Properties of shapes in the National Curriculum in England. Use your school’s sequence to decide when to introduce and revisit each skill. A game covers selected examples, rather than assessing every requirement.
Questions families ask
Where should we start with shapes and angles?
Start with Acute and obtuse angles. Look at the worked example together, then try a round. If the task feels unfamiliar, use the full game guide or its free printable before trying again.
