Spot and dot sentences are a fun way to practice identifying different phonics patterns. See the Silent-E-Freebie-Set for a sample. This set includes: Silent e, Bossy R, Diphthongs, Vowel Teams, Digraphs, Consonant-le, Silent Letters, and Long Vowels. Students should know all the ways that vowels can be long before the sentences for the Long Vowels a, e, i, o, and u are introduced. They should know about: Silent e, Vowel Teams, Tricky Y, Open syllables, and i & o can be long.
Simply print the pages for students to practice spotting and highlighting the phonics patterns. A set of answer keys is included. I like to use retractable highlighters for these, and the pages can be inserted into plastic report covers with two edges sealed with washi tape.
