Shape Detectives covers 2-D and 3-D shapes for Year 2 maths in three activities. Pupils name shapes, count sides and spot vertical lines of symmetry, count the faces, edges and vertices of a cube, pyramid and cylinder, then find the 2-D shapes hiding on 3-D solids, like the circle on the bottom of a cone. Answers included. Aligned to the England National Curriculum geometry objectives.
Geometry - properties of shapes
“Identify and describe the properties of 2-D shapes, including the number of sides and line symmetry in a vertical line”
The first table covers sides and vertical symmetry for each shape.
Geometry - properties of shapes
“Identify and describe the properties of 3-D shapes, including the number of edges, vertices and faces”
The second table counts all three properties for three solids.
Geometry - properties of shapes
“Identify 2-D shapes on the surface of 3-D shapes [for example, a circle on a cylinder and a triangle on a pyramid]”
Hidden 2D Shapes is this objective made into questions.
A table where pupils name each shape, count sides and judge vertical symmetry.
Faces, edges and vertices counted for a cube, square-based pyramid and cylinder.
Short questions like naming the flat shape on the bottom of a cone.
Answers for all three sections.
Main task
Give out real solids alongside the sheet so pupils can count by handling.
Assessment check
The property tables mark quickly against the key.
Homework
Pupils can hunt for the shapes on packaging at home.
