I'm not sure where I found this SMART notebook file (look under Beginning Readers; it is the 9th one down; called I See Colors Emergent Reader and Activity) from Mrs. Sears originally but I loved the idea. So I searched until I found it again on her site this time. We practiced this together as a class for the color we were learning each day. Then we made a word map of things that are that color as a class. Then the students used the writing sheet below to practice writing their own sentences to make a book (the cover is in the file below too).
I have been impressed with how well most of my kiddos have done with this being their first 'real' writing on their own.
As always I will put this in my Teacher's Notebook store in case Google Docs decides not to work!
