Our preK-4 school is happily using EPIC, whose school access now ends at 3 pm.  Since 4th grade science and social studies block is 3-3:30, they are looking for more resources.  I offered to purchase more ebooks (I don't have many, as they never get used), but am wondering about other resources.  We subscribe to World Book online, Pebble Go, Pebble Go Next, and Gale Elementary.  I have to find out exactly what topics they are in need of will study.  What about Libby from the public library? Do they have much in children's nonfiction?  Other thoughts?  Thank you.
