I’m considering the 8-10 level. I would love to hear from anyone who has used this and what your experience was like.
We really loved the Sarah, Plain and Tall Language Arts Unit (7-9 level), but didn’t care for the Science unit on The Land. I wrote a review of our experience for the Crew if you are interested: http://www.delightfullearning.net/2014/07/moving-beyond-page-unit-study.html
Hope it helps!
