He re-read his Unit 1 Review and his "Cat" book. He had two days (Friday and Saturday) off with no reading lessons and he is still retaining everything.
Week 1 turned out great!
Robbie likes his reading lessons. He completed Unit 1 (Lessons 1-3 and the review) in 4 days. I plan to have him re-read the previous lesson's book sometime during the next lesson (or after). I'll have to work out my review cycle.
