Section A: Mandatory content for Added Value Unit

1.1

Numeracy and statistics (Non calculator)

 

·         rounding solutions to a given number of decimal places

·         calculating whole number percentages of quantities

(single-digit percentages, multiples of 10%, multiples of 20%, multiples of 25%, 50%)

·         calculation of the mean of a data set requiring rounding

·         calculating simple fractions of quantities

·         adding two decimal numbers (some with a differing number of decimal places)

and then subtracting from the result

·         multiplying a decimal number by a single-digit whole number

1.2

Algebra, geometry and trigonometry

 

·         linear equations which require the use of the distributive law and simplification

·         problems using area (circle, parallelogram, kite, trapezium)surface area (prism) or volume (prism) 

·         creating and then using a formula (this can be from a numerical or diagrammatical sequence)

·         calculations involving speed, distance and time, where the time is given or calculated

as hours and minutes

·         using Pythagoras’ theorem in problem situations 

·         using trigonometry to calculate a side or angle of a right-angled triangle

·         solving problems involving the completion of a described shape using co-ordinates spread over

at least three quadrants (R)

1.3

Reasoning skills  : Identifying a valid strategy or explaining  a solution

 

·         Should be attached appropriately to questions involving operational skills
