An L1-2 investigation that covers direct proportion (best buy), and rounding / calculating with money /decimals. Two options are included: students can either research Easter egg and chocolate prices on internet shopping sites or use those given. In both cases they must investigate the cost per 100g chocolate and work out the best buy. Final extension work includes consideration of ‘buy one get one free’ and ‘two for £…’ offers.
