It depends. In some situations I like to provide students with some additional resources like a worksheet or two to give them a concentrated look at a topic that they may be struggling with. Students sometimes are a bit resistant to having homework on top of the assignments that they already have from their math class. I try to make it a small number of problems and they usually have a week to do them so it isn't too much and it really helps when they are behind and need to catch up.
Helping students succeed in math for over 15 years. Individualized attention makes the difference!
