_______________ are activities or assignments for the whole group that are designed to fill extra minutes and keep students meaningfully engaged in learning.

• A. Sponge activities
• B. Warm-ups
• C. Homework sets
• D. Reading circles

Answer: (A)

Having ready, quick activities that involve everyone is a smart way to keep learning active when extra minutes pop up. Sponge activities are designed to soak up those moments, keeping the whole class engaged with purposeful tasks that align to what was being taught. They’re short, simple to run, and require minimal setup, so you can smoothly transition back to the next part of the lesson without losing momentum. Examples include a fast vocabulary drill, a one-minute write or exit prompt, a short collaborative puzzle, or a quick think-pair-share that ties into the day's objective. The emphasis is on meaningful engagement, not busywork, and they should reinforce or preview content in a way that feels like a natural extension of learning.

Warm-ups, by contrast, are typically used at the start of class to activate prior knowledge, not to fill leftover minutes. Homework sets are assigned for completion outside of class time, not as in-class fillers. Reading circles focus on structured, small-group discussion of texts and aren’t designed to fill an entire class’s extra minutes for a whole-group activity.
