Hi Christy,
I typically just complete what is in the guide as well. However, I also like to add in some of the optional literature suggestions that are found in the Appendix of the guide. I like having that resource to refer to in case we want to expand our study time on a certain topic. For example, my daughter took a great interest in Joseph and Egypt so, I ended up purchasing some of the titles that were recommended for that particular unit.
Otherwise, just cruising through each daily lesson as written in the guide, is perfect too! 70 minutes sounds right on.
Have fun!
Candice
