I wrote in a posting last week that I intend to spend time this academic year talking about different aspects of the IB course in approximately the order (and time) they are taught. I have made the assumption that you will have started teaching topic 1 – Quantitative Chemistry (and not topic 2 – Atomic Structure – this was also discussed in a previous post last week).
Here is a link to a good website that gives you some free resources (and answers) for the teaching of topic 1 – Quantitative Chemistry.
