2. PERIMETER AND AREA Learn to figure out how to measure these…

3. PERIMETER DEFINITION: DEFINITION: THE DISTANCE AROUND A FIGURE All you do is ADD up the lengths of the SIDES of a polygon.

4. 55 10 WHAT DO WE NOTICE? NOW ADD UP ALL OF THE SIDES TO FIND THE PERIMETER 5 +10 + 5 + 10 =30

5. 55 10 WHAT DID WE DO? 1. Measurements 2. Add Up Sides 3. Get the Sum 4. Answer! 5 +10 + 5 + 10 = 30

6. 88 12 TRY THIS ONE!!!! FIND THE PERIMETER HINT: + 12 + 8 + 12 + 8 = 40

7. 7 7 7 FIND THE PERIMETER PERIMETER OF THIS = 21 7 + 7 + 7 = \ / 14 + 7 = 21

10. AREA HOW DO YOU FIND THE AREA OF A SHAPE?

11. My Name Is Stan Gable. I am the wealthiest and smartest man on the face of the Earth. I made all of my money by stumping children in math. I am here to try and stump you so I can make some more money and show just how intelligent I really am. You think you are smarter than me? I’ll make a deal with you all. I’ll give you some information about AREA. Then I’ll give you a few problems. If you get them right, I’ll leave you alone. But, if you get them wrong, I will take this cash all the way to the bank and buy your school where there will be no more fun EVER!!!!!!! The choice is yours… Good Luck! You sure will need it!!!!! MWAHAHAHAHAHA!!!! STAN GABLE INTELLIGENT MILLIONAIRE

12. WHEN MEASURING AREA… WHEN WE MEASURE AREA, WE USE SOMETHING CALLED UNITS. WHEN WE MEASURE AREA, WE USE SOMETHING CALLED UNITS. UNITS TELL US WHAT MEASURING TOOL WE ARE USING. UNITS TELL US WHAT MEASURING TOOL WE ARE USING. WE USE THE FOLLOWING: WE USE THE FOLLOWING:

13. UNITS TO MEASURE AREA SQUARE UNIT SQUARE UNIT SQUARE INCH SQUARE INCH SQUARE CENTIMETER SQUARE CENTIMETER SQUARE YARD SQUARE YARD SQUARE FEET SQUARE FEET

14. AREA DEFINITION: NUMBER OF SQUARE UNITS NEEDED TO COVER A FIGURE DEFINITION: NUMBER OF SQUARE UNITS NEEDED TO COVER A FIGURE 1 in 1 in The picture shows an area of 1 Square Inch HOW DID YOU GET THAT ?

15. AREA The measurements of the square’s sides are 1 in, 1 in., 1 in. and 1 in. That makes the perimeter 4 in. (1 in. + 1 in. + 1 in. + 1 in.= 4 in.) To find the AREA, you have to MULTIPLY the LENGTH of the shape by the WIDTH of the shape. Length x Width = Area OR L x W = A 1 in SO, that makes 1 in. x 1 in. = 1 SQUARE INCH

16. LENGTH WIDTH 3 UNITS 2 UNITS YOU CAN COUNT HOW MANY SQUARES THERE ARE TOTAL OR… Length x Width = Area L x W = A 3 units x 2 units = A Area = 6 SQUARE UNITS

17. LENGTH WIDTH 5 UNITS 3 U N I T S Length x Width = Area L x W = A 5 units x 3 units = A Area = 15 SQUARE UNITS I’d Knew You’d Get It! Try This Next Problem. It Will Surely Stump You!

18. LENGTH W I D T H 6 UNITS 4 U N I T S Length x Width = Area L x W = A 6 units x 4 units = A Area = 24 SQUARE UNITS So I See You Got Another One Correct! I Will Just Have To Do Something About This…

19. LENGTH W I D T H 6 UNITS 2 U N I T S Length x Width = Area L x W = A 6 units x 2 units = A Area = 12 SQUARE UNITS WOW!!! You really impressed me. I guess I can’t buy your school. But don’t worry, I’ll be back!!!!

20. YOU BEAT STAN!!!! WELL DONE MATH WIZARDS!!!! YOU BEAT STAN!!! NOW TO MAKE SURE HE DOESN’T RETURN, LET’S MAKE SURE WE DO MORE PRACTICE ON AREA!!! WE DON’T WANT HIM TAKING ALL THE FUN OUT OF SCHOOL!!!! WELL DONE MATH WIZARDS!!!! YOU BEAT STAN!!! NOW TO MAKE SURE HE DOESN’T RETURN, LET’S MAKE SURE WE DO MORE PRACTICE ON AREA!!! WE DON’T WANT HIM TAKING ALL THE FUN OUT OF SCHOOL!!!!

21. AREA REVIEW GAME SHOW STAN WHO’S BOSS SHOW STAN WHO’S BOSS SHOW STAN WHO’S BOSS SHOW STAN WHO’S BOSS YOU HAVEN’T SEEN THE LAST OF STAN GABLE! YOU JUST GOT LUCKY THIS TIME!!!!
