I have one quick question about the dictation passages I'm using in Bigger. We started at the beginning, and so far my son hasn't missed a single thing on any of them. Spelling is something that comes very easy for him and he seems to have a handle on. I'm a little surprised that he's remembered punctuation and capital letters, which seem to be much harder for him.

Anyway, I am totally new to using dictation, and I'm wondering if he hasn't missed anything in the 10 passages we've done so far if I'm starting out too easy. Should I look further back and pick a passage to start with that has more challenging words? Or will he still be benefiting from writing the passage correctly, and we'll eventually get to the passages that will challenge him more? I wasn't sure if there were "extra" passages in Bigger, or if there were only a year's worth.
Thanks in advance for your help!
