When I read the book "Jamberry" to my class, I fill a hat with pom poms in
shades of blue and purple. These look just like berries and the kids like to
spoon them out of the hat or use tweezers to take the out. This is great for
fine motor development.
Another game idea is to play a "Duck, Duck, Goose" style game. Replace the
words with "Blue, Blue, Berry" or "Jam, Jam, Berry".
