Here are a couple of worksheets to help year 4 children revise their knowledge of the properties of 2-D shapes. They should be able to recognise the most common triangles: equilateral, isosceles and scalene as well as most 4 sided shapes. Many maths books only show regular shapes eg a hexagon with equal sides, and many children do not realise that a hexagon does not have to have six equal sides – just six sides.
