My daughter is in 4th grade. She is having a hard time with division. I have her in tutoring 2 days a week, but it doesn't seem to be enough. I am looking for a online website for her to practice mon at home. Does anyone have any suggestion???

Khan Academy, however it's not going to be Investigations Math methods (if you are in Humble ISD). 

Math Mammoth is also a great resource. It's actually a homeschool curriculum (not done online) that you can download and print out, but it is EXCELLENT instruction and very inexpensive.

Kumon is a fantastic resource! They have workbooks you can buy at Barnes & Noble to do at home and they also have a learning center here in Kingwood. 

I taught my 4th graders to use the "big 7" to divide. It uses only 10 (and multiples of 10 with larger numbers), 5, 2 and 1. If you want me to send you an example PM me your email address. This method works well with Investigations.
