Hi Kerry,
You can use learning groups where the students work together on new content. Also, you can have students do mini-presentations on different topics. Create a game like Jeopardy or create teams and have competitions. What you will find with this kind of variety is that you can use PowerPoint when you need to because students are not being shown a PP every day. Make sure the PP is brief to the point, colorful, graphic and not filled with too much text and the students won't mind it near as much.
