# Year 8 Algebra Recap

## 1 files28/05/2016

(a) Revision of simplifying algebraic expressions (multiplying, dividing, adding, expanding single brackets).

(b) Revision of solving simple equations, e.g. (x2 - 7)/2 = 9 and 1 - 3x = 2x - 7# Changing the Subject (pre-GCSE)

## 8 files24/05/2016

(Based on the Tiffin Year 8 scheme of work) (a) Change the subject of any formula where the new subject appears only once. Includes roots, squares, brackets, where x appears within a negative term and/or in the denominator.

(b) Be able to cross multiply.

(c) Determine a value when the formula and values of all other variables are given.# Constructions (pre-GCSE)

## 3 files28/05/2016

(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.# Bearings

## 2 files12/06/2018

(Used for the Tiffin Year 8 scheme of work)

Understand bearings and scale drawings.# Polygons and Interior/Exterior Angles

## 3 files05/06/2016

(a) Understand the definition of different quadrilaterals (kite, trapezium, rhombus, parallelogram).

(b) Know properties that quadrilaterals have, i.e. symmetry, diagonals, rotational symmetry, etc.

(c) Know that a polygon is regular if its lengths and angles are all equal.

(d) Know the angle sum of interior angles given the number of sides, and of exterior angles.

(e) Determine each interior/exterior angle of a regular polygon.

(f) Determine the number of sides a regular polygon has given each exterior or interior angle.
