Hold old are they?????
• Look at the image of the celebrity and
estimate their age. Write your estimate on
the chart under the estimated age column.
• Write their actual age in the actual age
column.
• Calculate the difference to determine how

Reflection Questions
1. If Jim guesses Will Smith was 50 and Sue
guesses he is 42, who is closer to his actual
age of 46? Who would win?
2. Who thinks that Jim and Sue are tied?
Answer yes or no and explain your answer.
3. Absolute value of a number is its distance
from zero on an number line. How is this like
guessing someone’s age?
Reflection Question Responses
1. Jim’s guess is 4 years over his actual age. Sue’s guess is 4
years under his actual age. Neither person wins.
2. It is a tie. Both people guessed 4 years from Will Smith’s
actual age. Even though Jim’s guess is over, he is still 4
years from Will’s actual age. Sue’s guess is under but not
a negative number. It is also 4 years from Will’s actual
age.
3. Guessing someone’s age is very similar to a number’s
absolute value. A guess can be either over or under the
person’s actual age but is still a positive number (the
distance from the person’s actual age). Just like absolute
values are always a positive number (counting the
distance from zero on a number line).
