Focus: Using the Ball Park Strategy to Solve Problems When you go to a baseball game, the park is set up something like this. Where is the game played? Where does the crowd sit? What do these lines mean?

So, these lines are the FOUL LINES. What would happen if a player hit the ball, and it landed where you see a red “x”? X It’s a FAIR ball!

What would happen if a player hit the ball, and it landed where you see a red “x”? X It’s a FOUL ball!

What would happen if a player hit the ball, and it landed where you see a red “x”? X It’s a FOUL ball!

So, anything hit between the foul lines is fair. Anything hit outside of the foul lines is foul. FairFoul

Michael went to baseball camp for 3 days. Each day he hit between 5 and 10 home runs. What is a possible number of home runs he could have hit? a. 5 b. 10 c. 25 d. 50 What do these problems have in common? Jane baked cookies for 5 hours. She made between 30 and 50 cookies each hour. What is a possible number of cookies she could have baked? a. 100 b. 125 c. 145 d. 175

Amount of time Between x x Multiply these numbers Least possible number goes here. Greatest possible number goes here. = =

Amount of time Between Possible numbers Anything in between these numbers is “fair.” Anything smaller than this number is “foul.” Anything larger than this number is “foul.” x x = =
