My kids would revolt if we tried to do an entire fluency page, it's too much!
We do the top line of every segment one day, the 2nd the next and so on. Sometimes we even skip some of the fluency pages. Level 2 fluency pages are longer.... I have my kids read a portion of the fluency pages during school time, at bed time I have them pick a story or 2 from the level 1 readers. My kids are not fluent, fluency practice pages are not our path to fluency.
Don't abandon the program, abandon the fluency pages!
