An angles warm-up for Year 4 maths, five questions long. Pupils label angles as acute, right or obtuse, order a set from smallest to largest, then count the acute angles in a shape and answer a true or false on whether an obtuse angle is always larger than a right angle. All five answers are included. Opens the England National Curriculum work on comparing angles up to two right angles.
Geometry - properties of shapes
“Identify acute and obtuse angles and compare and order angles up to two right angles by size”
All five questions sit inside this objective, from naming to ordering.
Geometry - properties of shapes
“Compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes”
The angles-in-shapes section links angles back to shape properties.
Label each pictured angle as acute, right or obtuse.
Write the letters of the angles in order from smallest to largest.
Count the acute angles in a shape, plus a true or false on obtuse versus right angles.
