At my school, we really stress fluency. I got a great idea from another third grade teacher. We keep binders for each student. Each week, we discuss one of the following...
1 week - Readers theater
2 week - poem
3 week - timed passage
For reader's theater we get a copy of a short play. I divide the class into parts, and they practice their parts every day and perform on Friday's in front of the class. It is up to the groups to determine who gets what part.
Poems- Make a copy of a short poem. Talk about reading the poem with fluency (expressions, accuracy with the words, phrasing). Use highlighters to highlight important factors like end marks and phrasing. The kids study this poem daily and recite the poem in front of the class. I usually model the way I expect the poem to sound on Mondays.
Timed reading - We "dibble" in our system which is a timed reading passage. We make copies of a short story that is timed. On Monday's the kids read it to me "cold turkey", They color in a bar graph how many words they read. During the week, the practice this... On Friday, I re-time them and then they color in how many "more" words they read... I hope you can get a visual here....
This is all kept in their "fluency folder'. IT mights take a little time to get things going, but after going through the first examples of each, it runs smooth as silk. They really get into character, they love it... They love to see their improvements each week.
Hope this helps.... I usually spend about 10 minutes each day on this.. Not much time, once they get the underlying concept.
