Agreeing except to say depending upon what literature you’ve chosen to read aloud, you may not need a change there. My dd6 is in 1st officially and we didn’t do anything really for K other than read books and play at math. She taught herself to read and at a ridiculously advanced level. I’m not sure, but I’d put her at a 6-7 grade level re. ability. However, there are WAY TOO MANY amazing books written between 1-7 levels for her to miss. Currently, I’m reading Paddle to the Sea, Outdoor Secrets, and Just So Stories to her for school. She could read these easily on her own, but too bad. I enjoy sharing them with her too much! She likes listening to the stories, too, even though she sits beside me and reads along. For her individual literature reading, she enjoys everything! She has read many chapter books and is eager for more. Right now she’s happy with Boxcar Children, Centerburg Tales and the like. I’ve got enough ideas for a year or two and then I’m going to scratch my head for things appropriate for her age that she hasn’t read! All that to say your lit may be fien and not need a change!
