More Looking for Long Vowels...Digraphs!

Here is the latest addition to my long vowel activities.  This activity can be completed independently or with other students.  There is a separate worksheet for each long vowel sound and digraphs, which makes differentiation fairly easy.  I designed the activity to meet the needs of my first grade students in the Words Their Way middle vowels category; however the activity also lends itself to enhancing and supporting the skill sets introduced in our class reading curriculum.  My goal with these activities is to make my students more aware of what they are reading, and to help them practice both the silent 'e' and digraph spelling patterns.  My next step is to design another level of activities that requires the students to apply what they have learned in both reading and writing.  Let me know what you think, and if anyone might try using these with their students.
Here is a sample~
