You’re probably correct that on her SCM GUide regarding ‘family’ and the ‘plus’ section; however, you can read aloud as many as you like and have them read independently as many as you want. So whether to read aloud or independently is ultimately your decision.
I also looked at the Mod. 4 and their aren’t any that do too much overlapping. The family section has “spines” as overview books. I personally don’t see any in the ‘plus’ section that I would leave out. If your child isn’t ready to read LEif the Lucky by him/herself, then you can read it aloud.
