Many kids who like lessons that are not intimidating use online or CD-based curriculum. It seems to be better for many reading and attention issues. The current leader is either Switched on Schoolhouse (which had lead for years) or Time4Learning.com . Switched on schoolhouse is CD-based. Time4Learning is web based curriculum with a simple month by month arrangement. Give them a try since signup is quick and with a full refund for two weeks. I used their money-bakc guarantee twice: once to see if I liked it for my younger kid (kindergarten) and then again for my 8th grader.
Their reading program is great. Simple, sometimes funny, sometimes silly but it systematically takes the kids thru the curriculum of reading comprehension and vocabulary and reading fluency. Also, you can switch grade levels at any time
