This list is by no means exhaustive, but hopefully is a good place for new Econ teachers to start. If I've missed out any useful references or if new ones have come along, do let me know and I'll pop them on.
I also send out an email twice a month or so with the best resources for A-Level Economics I've found from around the web. Feel free to join the list by entering your address below; worksheets, Articles, CPD, Activities, Resources, Tools, Data...Whatever I find, I'll send your way. I try to only share genuinely useful things, but if it turns out the resources aren't your cup of tea, there's an unsubscribe link at the bottom of each email.
