Children will be expected to be able to identify, visualise and describe 2D shapes and 3D solids. They will use their knowledge of the properties of 2D shapes to draw them and to identify nets of 3D shapes. Plotting co-ordinates in the first quadrant is introduced as well as terms such as parallel and perpendicular. Acute and obtuse angles are estimated and drawn, using suitable measuring equipment.
Looking at the properties of cuboids, prisms and pyramids.
Finding out what congruent shapes are, how to recognise a scalene triangle and using Venn diagrams and tree diagrams to classify shapes.
Nets of cubes and pyramids and making 3D shapes from cubes. Using a pinboard to make 2D shapes that obey set rules.
More nets of 3D shapes which can be cut out and folded to make the shapes.
Net of a 12 sided shape, more on nets for a cube and some ideas for tangrams.
Using co-ordinates in the first quadrant to make shapes and solve problems.
Parallel lines are always the same distance apart and perpendicular lines are at right angles to each other.
2D shapes may have lots of axes of symmetry, or none at all!
Reflective symmetry; a mirror is really useful to help visualise this.
An acute angle is greater than zero degrees and less than 90 degrees. An obtuse angle is greater than 90 degrees but less than 180 degrees.
Practice at estimating and measuring angles. Remember, angle is a measure of turn.
More on measuring angles and calculating angles from given information.
