Alphabet Island Level 1 is basically for Kindergarten. There are two workbooks, 2-A and 2-B in Level 2 that cover 1st through 3rd grade material and the “big” patterns of phonics. When you finish with the Alphabet Island, you may continue teaching spelling with the Eagle’s Wings Comprehensive Handbook of Phonics for 4th through 9th grade. You will have covered about 40 of the 83 charts in that book when you finished Alphabet Island Level 2.
