Yes, that's what I've seen in my kids' elementary classes. Teachers seem to deliberately go incredibly slowly with instruction, particularly in the lower grades, and then they give a lot of time to complete the subsequent work, which most kids actually take. This is one facet of the quintessential problem of our kids' learning much more quickly.
Dude is right. You need to work with the teacher to come up with a solution, and usually it winds up with the student reading on their own out of a book from home.
The other option is troublemaking.
