In the Math program we use at our school there are "Meeting Masters" that students complete each day to practice the spiraling math curriculum. This is just one (lesson 101) of an entire year's worth of masters created to follow all 135 third grade lessons. These were created especially to be displayed on the Smartboard interactive white board using the Notebook software. In my classroom, the students correct their masters when we do the math meeting later in the day. If the teacher so chooses, they can also be corrected right on the master as it is displayed on the smartboard, allowing students to write in their own answers if they'd prefer.
