My 4th/5th grade classroom has a class of kindergarten buddies. Every other week, I make up activities to do with them. I created a Turkey packet to use for this time of the year. The packet includes a reader that focuses on colors, two color identification sheets, and a turkey glyph project. My kids complete all of these activities with our kindergarten buddies in one 45 minute period and help the little ones to do the work.
If you have not tried having your intermediate classroom "adopt" a younger buddy class, you should! It is a great experience for both groups of kids!
