With the older four, I don't really have to encourage reading, but I do want them to stay on top of their math facts. So, every couple of days, we have "school" time for 30 minutes where they have to do math facts.
Except Mac, he has to read. He is a little behind in reading and we are trying to catch up to an appropriate level this Summer. On this particular day, I asked the boys to listen to him read. It made him as nervous as anything, but they were so sweet and patient with him. I loved it!
