Entering the Math… • How do we decide who guessed the best? • Can we stop searching for the best guesser now? • How far away were you from the actual age of the celebrity?
How far off where you??? • Add a new column to your chart titled: “How far off” What types of numbers should we use if we underguessed? Overguessed?
What is better? • To underguess by 30 years? Or, overguess by 30 years?
Absolute value: • Is the distance from a number on the number line. • Typically, how far a number is away from zero on the number line.
