Hi Erin and Mela,
Thanks for your input Mela!
What you want to do with your binder is really up to you, the binder can be quite useful if you want to teach in a different environment without a computer. What Mela said is a good suggestion.
Regarding downloading the LR and LM curriculum online.
If you have downloaded and installed the curriculum online already, there is no need to install it from the CDs. The CDs primarily serve as a backup in case you can't access the downloads online (we update the curriculum and software version online from time to time so it's best to download online).
Hope this helps and happy teaching!
