Midpoint Formula Discovery

1. Where is the midpoint between A and B? Make a guess and add drag point G to that location. 2. Use the "Midpoint" and "How close was I?" checkbox to see how close you were to the midpoint. 3. Use the "A and B Values" checkbox to see the coordinate values of A and B. 4. Guess what the coordinate value of the midpoint should be. 5. Use the "Midpoint Value" checkbox to check your answer. Drag A and B to another location and guess again. Can you get closer this time?
