Divide the class into groups.Give each group a different text to read.After the group had quiet reading time(a predetermined amount(5-10 min), the teacher makes a class contest.she writes columns on board for each group.asks questions and the group that answered most wins! this can be done in various forms such as all groups get same text or instead of questions, teacher writes words on board and the groups get turn in reading...
contests create fun!
if you have two or three teachers in class, divide into groups and each teacher sits with one group and hears them read and asks questions according to their level.each groups is expected to know according to their level and the worksheets and/or questions given accordingly.for very weak groups teacher does activity or game to make easier learning.

Children, as adults, learn better if the lesson is taught in a fun and exciting manner.I find that games, such as matching games, contests between students and physical jumping games bring out the fun in reading and encourage children to read through playing.they sometimes dont even realize they are doing hard work because they are having fun.research games and activities for reading and you will see the difference right away!
