This fully-resourced lesson with differentiated resources has been written to prepare students for the range of mathematical-based questions they may face on the two Edexcel GCSE Chemistry papers. The lesson has been designed to contain a wide range of activities which includes 8 quiz competition rounds spread across the duration of the lesson to maintain engagement whilst the students assess their understanding.

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
  • Calculating the relative atomic mass using isotope mass and abundance
  • 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 concentration of solutions
  • Titration calculations
  • Deducing the empirical formula
  • Calculating energy changes in reactions

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

This lesson could be used with higher ability students on the Edexcel GCSE Combined Science course by taking out the sections which are not applicable.
