Here is a fishbowl uppercase and lowercase sorting activity. I printed all the patterns on cardstock paper ... cut them out and attached the letter fish to craft sticks.
I attached the fishbowls to the front of clear plastic cups and set them out along with the letter fish. In this activity the children put the fish into the correct cups based on whether it was an uppercase or a lowercase letter.
The fishbowls can also be glued onto a sheet of construction or cardstock paper and the children would put the loose fish (not attached onto craft sticks) on the correct mats. As of 2022 this activity can be found in the member's section which is also where the fishbowl number sort is located.
