Bossy "R" Flip Books.. Steps: 1. Fold paper hotdog style. 2. Cut front flap into 5 sections. 3. Label each section (ar, ir, er, ur, or) 4. Color code the vowels by sound. ex. ar - orange ir, er, ur - blue or - green 5. Open one flap at a time and think of a word with that vowel sound and write inside the flap. (For differentiation my higher groups wrote sentences with the words and some used more than one matching vowel word. WOW!) 6. Draw a picture inside to go along with your sentence.
