If you've been looking for an interactive daily oral practice of 50 roots (Bellringers) to build your students' vocabulary, this is the power point for you.
The answers show up one at a time at the click of the mouse. Students can guess the answers and then check interactively.
I've used it on ActivInspire too. Just cover the answer with an "object" and let the students check by moving the "object." They love it.
I used 50 different root families--enough for a whole year. By starting over when you finish all 50, the students get more practice with them and they retain them better.
