To find Romesh's mean score, we can use connecting cubes.

1. If each connecting cube represents one point, how many connecting cubes do you need to represent all the points Romesh scored?
2. Make 5 towers, one for each game with the points Romesh scored in that game.
3. Divide the connecting cubes into 5 equal towers. Think of this as dividing all the points evenly among the five games.

2. How many connecting cubes are in each tower?

Romesh's mean score is 13 points. We can say he averaged 13 points per game.

To find his mean points per game on a calculator, Romesh used the following keystrokes:

• 

He added his points and then divided by the number of games.

3. Which average, the mean or the median, do you think better describes Romesh's scores? Explain your thinking.
