If you visit my Guided Reading Section in my curriculum page, you see a description of what reading workshop is.
Each day students are placed in tiered groups high-medium-low and are given various centers to interact with. Each center reinforces previous skills taught such as word families, sight words, phonics, and the like.
Then myself or my teacher assistant will call over students to read books based on the reading level they are at. Each book selected is related to the theme that we are at in our class. In small groups students read their books and are given comprehension activities that go along with the book.
One of our reading groups read “This Is My Bear”, and then they classified and sorted pictures that they saw. The students are guided to recognize the pictures can be sorted by pictures of Teddy Bears and pictures that are not Teddy Bears.
