This 40-page packet includes the materials for five different literacy centers, (a, e, i, o, u) each comparing long and short vowel sounds. For each center, students will be given a group of sixteen words printed on crayon templates. Students will read each word and put it in the correct crayon box. After sorting all the words, they will record them on an accompanying worksheet so teachers can assess their understanding. Blank templates are also included so teachers can create their own centers addressing different skills.
