There are some things, a texbook won't tell you about fluency. In Texas public schools,
1st. grade should be reading 60 words per minute with unsssen test. 2nd. grade should read 90 words per minute and 3rd grade should read 120 words per minute with unseen text.
Thus, fluency be a big deal! To get children to read and write fluenty offering suggestions and activities to help struggling students. But always remember READING MEANS COMPREHENSION.

I will to recommend to you "One pizza, One Penny" by K.T. Hao, He is considered the founder of moder'n children's literature in Taiwan.
It is a charming portrayal of two friends. Ben Bear is renowned for his perfect pizzas. Chris Croc is famous for his mouthwatering cakes. When the richest man in the world buys a slice of Chris's pizza, he decides to go into business. But as soon as he sets up his roadside stand, Ben sets up one of his own across the street, and the neighbors turn into fierce rivals. Slow business and creeping hunger force the two chefs to come up with a solution that shows that friendship is the best possible nourishment.
Remember, Comprehension is a thinking process that is creative, multifaceted and engaging!
Hasta la vista!
