This document has 5 days of sponge activities to begin class with for lesson 27. 3 of the activities are oral activities that I call "pile ou face", a technique I learned at a conference. I name off every other row as pile or face. We flip a coin. If it lands on face (heads), then the rows that are labeled face will move while the piles stay stationary. If it lands on pile (tails), then the pile rows move while the faces stay stationary. Every few minutes I will instruct students to change partners, which is where the moving comes into play. I have students move from the front to the back of the rows. This insures that students converse with a variety of other students. We do this for about the first 10 minutes of class, and then I go over the questions with them as a class. When they answer a question, they earn oral participation credit. Since they've gone over the questions and answers with various partners in the class, it lowers the stress level for participating. Many of my questions I change up every year and personalize them for the students in my class by asking questions about them and using their names, which heightens their interest even more.
The "revision" activities students complete in their notebooks, which also houses their notes. I collect these notebooks every few weeks and give them a credit grade for. When they have finished the "revision", we correct it as a class. I used to do these on overheads, which you can still make them into overheads, but now that I have a digital white board, I just project the documents onto the whiteboard. This saves paper and trees.
These activities provide teachers with the time to take roll and deal with housekeeping issues such as absent students and make up work at the beginning of class.
