Is it a pull out class? Extensions on the work can be valuable as long as the work itself is appropriate. If the actual work is not at an appropriate level, then a small amount of extension work won't help much.
It sounds as though your child will be expected to do the extensions as well as all of the regular class work. If it's a pull out, they aren't supposed to have to make up the work they miss (this is best practices and in some state standards, but teachers don't always know that). The work in the pull out program should be a substitute, not just an extension.
The extensions may be great, but it doesn't sound like a strong program unless the differentiation mentioned in question 4 is really strong. It doesn't give you any idea of what the differentiation is, though.
