Construct organic compounds using either of the 6 types of formulae

Students will be able to take rich notes on types of formulae, building on their KS4 knowledge on this topic

The teacher will be able to quickly assess students’ understanding of the how to calculate types of formulae by carrying our mini AfL tasks either on mini white boards or in students’ books
