Some teachers like to take attendance verbally, especially at the beginning of the year, in order to learn students' names.
This doc contains 90 ideas for attendance callbacks.
Instead of saying, "HERE!," students respond with the topic for the day.
For example, tell students they must respond with an animal in the ocean. Students cannot use the same animal, so they must listen to each other's response.
This is easy to edit and adapt as needed.
