After reading Blueberries for Sal, children will want to try their hand at picking blueberries.
Take blue plastic cups and affix a handle to the top. Spread small plastic counting cubes on floor and have children collect and put them into their "pails. After collecting have children count out the number of berries they have collected.
Have children reenact the story.
