Producing drawings on isometric paper.
(a) Draw the front elevation, side elevation and plan from a 3D shape, and vice versa. (b) Draw 3D shapes on an isometric grid.
(a) Recap: Construct triangles, equilateral triangles, perpendicular bisectors, angle bisectors, perpendicular from a point on a line, and perpendicular to a line from a point not on the line. (b) Construct a hexagon. (c) Appreciate that a locus of points is a set of points which satisfies some criteria (e.g. a distance of 10cm from an object). (d) Identify loci for (i) a fixed distance from a shape (ii) equidistant from two points (iii) equidistant from two lines. (e) Find loci for compound shapes (e.g. fixed distance from a rectilinear shape). (f) Identify loci regions, e.g. less than a specific distance from a shape. Combine regions from multiple criteria.
(Used for the Tiffin Year 8 scheme of work. Does not include loci.) (a) Construct triangles given SAS (Side-Angle-Side), ASA, SSS. (b) Construct perpendicular and angle bisectors, angles of 30, 45, 60 and 90, and the perpendicular from a point on a line.
Key Skills are finegrained question types where students can practise randomly generated questions with accompanying short worked-example videos.
