Give your student some books about intermediate algebra to take home. When deciding on which books to give him, choose algebra books that have the most detailed instructions on a variety of algebra problems. Don't choose books which have too many shortcuts in the instructions because these books may confuse your student.
Do practice algebra problems with the student. For example, if your student is struggling with graphing linear equations, print out some worksheets from a local university's math lab website and discuss how the student can effecively graph the equations. Then solve five to ten problems and critique the student's answers, and if there are incorrect answers, show her why they're wrong and how to correct the mistakes.
Watch some algebra tutorials on DVD together. Periodically pause the DVD to explain in further detail certain concepts so the student can understand what's being taught in the tutorial.
