Support (from Y7 teaching programme)
• Use ruler and protractor to construct simple nets of 3-D shapes, e.g. cuboid, regular tetrahedron, square-based pyramid, triangular prism
• Use conventions and notation for 2-D coordinates in all four quadrants; find coordinates of points determined by geometric information.
• Use a ruler and protractor to (a) measure and draw lines to the nearest millimetre and angles, including reflex angles, to the nearest degree (b) construct a triangle given two sides and the included angle (SAS) or two angles and the included side (ASA); explore these constructions using ICT.
|
Core (from Y8 teaching programme)
• Know and use geometric properties of cuboids and shapes made from cuboids; begin to use plans and elevations.
• Make simple scale drawings
• Use straight edge and compasses to construct a triangle, given three sides (SSS); use ICT to explore these constructions.
• Given the coordinates of points A and B, find the mid-point of the line segment AB
|
Extension (from Y9 teaching programme)
• Visualise and use 2-D representations of 3-D objects; analyse 3-D shapes through 2-D projections, including plans and elevations.
• Use and interpret maps, scale drawings
• Use straight edge and compasses to construct a triangle, given right angle, hypotenuse and side (RHS)

PRESTAGE / PERKS
~ Change the resources used for construction; e.g.to draw a triangle with angles 30°, 60°, 90°, use a protractor and ruler; pair of compasses and ruler; Cabri geometry; calculator and 45° set square etc (p26 and p45)

~ Given 2 elevations (or 1 elevation and a plan) of a 3-D shape, what could the shape be?
How many different triangles can be made with SSS, SAS, SSA? |
