Excited!! I finally decided to use Words Their Way with my 4th graders. We don't have a spelling program in our school... actually spelling isn't a focus at all and it is a complete shame and I see the problems developing as a result. I purchased the main WTW book.. and I felt for my 4th graders I would need the yellow book (Within Word Patterns) and the green book (syllables and affixes). I figure I will have 3-4 spelling groups who will be working on different sorts at once. Any tips, suggestions, comments about Words Their Way. I'm really excited to get my 4th graders back on track with spelling this year.
