Maths in AQA GCSE Chemistry REVISION

A fully-resourced lesson which prepares students for the range of mathematical-based questions that they could encounter on the two AQA GCSE Chemistry papers. The lesson contains a wide range of activities which include exam-style questions with markschemes embedded within the PowerPoint to enable the students to assess their current understanding. There are also 8 quiz competition rounds interspersed throughout the lesson to maintain engagement and motivation.

The mathematical skills covered in this lesson include:

Calculating the number of sub-atomic particles in atoms and ions
Writing chemical formulae for ionic compounds
Identifying isotopes
Using Avogadro’s constant to calculate the number of particles
Calculating the relative formula mass
Calculating amount in moles using the mass and the relative formula mass
Balancing chemical symbol equations
Calculating reacting masses
Gas calculations using molar volume
Calculating the concentration of an unknown solution
Calculating the atom economy and percentage yield
Calculating energy changes in reactions
Temperature and pressure and the position of equilibrium

Most of the resources have been differentiated two ways to allow students of differing abilities to access the work whilst still being challenged. In addition, step by step guides are used to demonstrate how to carry out some of the more difficult calculations such as the harder mole calculations and calculating masses in reactions
