I came across this the other day--Explode the Code Online workbooks! Those same workbooks you can purchase for your child to do at home are also available as an online game. You purchase a one year subscription for your student, and the Explode the Code online game keeps track of their progress for you. Each progression of phonics questions is based on what your student has accomplished already! There is a 4 minute video explaining the game that you can watch on the website. The game looks very interactive and fun! I know Little Bean would love this a lot more than he does the workbooks!
We just finished up Book 1, which was ALL review for him, but it was good practice for him to work totally independently and for his fluency. I already have books 2 and 3, but I just may have to consider this for the rest of the levels after that!
