I would add to the saying "when two vowels go walking the first one does the talking and USUALLY says its name." this will give the students the decoding strategy that if the vowel name doesn't work try the short vowel sound... one or the other should handle most words. Also I would put these up on the blackboard while using them but not on the wall.
I don't think I've seen this pinned here, but this would be a huge hit! :) Sentence Surgery…laminated unedited sentence strips, bandaid strips for ending punctuation, small round bandages for commas and quotations, tongue depressors to mark capitalization, and ‘Emergency Kit’ paper bags w/ red cross on them (to keep surgery supplies).
