Students will be required to demonstrate the following mathematics skills in GCSE Chemistry assessments. Questions will target maths skills at a level of demand appropriate to each subject. In Foundation Tier papers questions assessing maths requirements will not be lower than that expected at Key Stage 3 (as outlined in Mathematics Programmes of Study: Key Stage 3, by the DfE, document reference DFE-00179-2013). In Higher Tier papers questions assessing maths requirements will not be lower than that of questions and tasks in assessments for the Foundation Tier in a GCSE Qualification in Mathematics.

d | Make estimates of the results of simple calculations |
2 | Handling data |
|---|
a | Use an appropriate number of significant figures |
b | Find arithmetic means |

3 | Algebra |
|---|
a | Understand and use the symbols: =, <, <<, >>, >, ∝ , ~ |

c | Substitute numerical values into algebraic equations using appropriate units for physical quantities |
4 | Graphs |
|---|
a | Translate information between graphical and numeric form |
b | Understand that y = mx + c represents a linear relationship |
c | Plot two variables from experimental or other data |
d | Determine the slope and intercept of a linear graph |
e | Draw and use the slope of a tangent to a curve as a measure of rate of change |
5 | Geometry and trigonometry |

c | Calculate areas of triangles and rectangles, surface areas and volumes of cubes |
Mathematical skills references are taken from the DfE subject criteria. Where there is a break in a sequence, the 'missing' references are criteria not applicable to GCSE Chemistry and have been deliberately omitted from this list.
