Learning intentions
- Develop understanding of the progression of learning in geometry
for pupils from year 1 to year 6.
- Develop understanding of the properties of 2D and 3D shapes and
the related vocabulary.
- Become aware of some of the common errors and misconceptions
relating to 2D and 3D shapes.
- Develop understanding of angles and transformations.
Triangles
Scalen Isoscele
Many young children do not recognise shapes that aren’t orientated on
Equilate
ral
their base. The teacher needs to ensure they present shapes in every
orientation so the children know how the shapes look in different
orientations.
Rectangles
Rectangle – 4 straight sides, 2 sets of parallel sides, 4 right angles
Square – a special rectangle
Oblong – any rectangle that is not a square
Quadrilateral
One pair of parallel sides
No parallel sides
Two pairs of
parallel
sides
Trapezium
Kite Parallelogram
4 equal sides,
All angles 90°
opposite angles
equal Rectangle
Rhombus
‘Learning and Teaching Point -
