2 2 John bought 5 meters of rope, How many centimeters does he have? 5 m = _____cm

3 3 5 m = 500 cm 5 x 100 Going from bigger to smaller you multiply! 2 jumps or x 100

4 4 Karen’s tape had a length of 31 mm How many centimeters of tape does Karen have? 31 mm = _______ cm

5 5 31 mm = 3.1 cm Going from smaller to larger, you divide, since you move to the left one space you divide by 10

6 6 Nick ran 1.6 kilometers, how Many meters did he run? 1.6 km = ______ m

7 7 1.6 km = 1600 m Going from bigger to smaller you multiply. To go from km to m you multiply by 1000 or move the decimal 3 places to the right.

8 8 Mike walked 5750 meters, how many kilometers did he walk? 5750 m = _______ km

9 m = 5.75 km Divide by 1000 or move the decimal three places to the left.

10 10 Peter caught 2 fish. One weighed 5.1 kg and the other weighed 4.8 kg. How many grams of fish did he catch in total?

11 11 Change the weight of the fish from kilograms to grams and add them 5.1 kg = 5100 g 4.8 kg = 4800 g Therefore = 9900 grams

12 12 Joe had 4 quarts of soda. How many pints did he have? 4 qt = ______ pt 2 pints = 1 quart

13 13 If 1 qt = 2 pt 4 qt = ____ pt 4 qt = 8 pt

14 14 Paul played soccer for about 3 hours each day for 20 days. How many hours is this?

15 15 If Paul played soccer for about 3 hours each day for 20 days. Paul plays soccer of 60 hours. Since 1 day = 24 hours 1 day = 24 hours ½ day = 12 hours 2 ½ days = 60 hours

16 16 Mr. L bought 36 ounces of peanuts. If 16 oz = 1 pounds, how many pounds of peanuts did he buy?

17 17 Mr. L bought 36 ounces of peanuts. If 16 oz = 1 pounds, how many pounds of peanuts did he buy? Cross Multiply 16? = 36 ? = 36 ÷ 16 ? = 2.25 pounds

18 18 Isabel read a book for 750 minutes. How many hours is this?

19 19 Isabel read a book for 750 minutes for the month. How many hours is this? 750 ÷ 60 = 12 ½ hours? Isabel read for 12 ½ hours for the month

22 22 How much wood does John need to surround his door way? 3 ft 6 ft 2 ft

23 23 Add all the sides = 20 ft John needs 20 feet of wood for a border around his door 3 ft 6 ft 2 ft

24 24 How much paper will Greg need to wrap the box? Find the surface area of the container. Remember find the area of the TOP, SIDE, and FRONT, then SA = (Top + Side + Front) x 2 l = 5 ft w = 3 ft h = 4 ft

25 25 l = 5 ft w = 3 ft h = 4 ft Area Front = 5 x 4 = 20 ft² Area of Side = 3 x 4 = 12 ft² Area of Top = 5 x 3 = 15 ft² SA = (Front + Side + Top) x 2 ( ) x 2 (47 x2) = 94 ft²

26 26 Lauren wants to make a circular table for her kitchen. Around the table, she want to put a border of rope. How much rope will she need? Find the circumference of the circle, if the diameter of the circle is 5 ft C = 2 ∏r C = ∏d

27 27 Given C = ∏d = 3.14 x 5 = 15.7 ft So Lauren will need 15.7 ft or about 16 feet of rope to surround the circular table. d = 5

28 28 Dan wanted to frame his picture using a regular shaped pentagon. How much wood will he need if one side of the pentagon measured 8 inches? 8 in.

29 29 Since a regular shaped pentagon has all the sides equal. If the pentagon Has 5 sides and each side is 8 in 5 x 8 = 40 inches of wood 8 in.

30 30 John’s backyard looked like the diagram below. How much fencing will he need to buy to surround his yard? Remember to find the missing lengths. 24 m ? m 14 m 12 m 20 m ? m

31 31 24 m 12 m 14 m 12 m 20 m 8 m John needs = 88 meters of fencing

32 32 John painted a picture that had an area of 50 in². What is the amount of area around the picture that is not painted? 12 in 10 in

33 33 The area around the picture is AREA = 12 x 10 = 120 in². Since the picture is 50 in². Subtract 50 from 120 to find the area that is not painted. 120 – 50 = 70 in² 12 in 10 in 50 in² 120 in²

34 34 Tom painted a large triangle on his wall. What is the area of the triangle? 9 ft 15 ft Area = (b x h ÷ 2) or Area = ½ (bxh)

35 35 Tom will paint 65.5 ft² AREA = (b x h ÷ 2) (15 x 9 ÷ 2) (135 ÷ 2) = 67.5 ft² 9 ft 15 ft

36 36 Marty made a birdhouse, the front of the birdhouse was the shape of a triangle. What is the area of the door opening of the birdhouse? Let ∏ = 3.14 radius = 6 in Area = ∏r²

37 37 Marty used the formula AREA of Circle = ∏r ² 3.14 x 6 x in² radius = 6 in Area = ∏r²

38 38 John wants to fix his backyard with grass seed? What is the area of his backyard if it looked like this? Use the following formula! a = 10 ft b = 15 ft h = 12 ft A = ½ (a + b)h

39 39 a = 10 ft b = 15 ft h = 12 ft A = ½ (a + b)h A = ½ ( )x12 = ½ (150) x 12 = 75 x 12 = 900 ft²

40 40 38 m ? m 24 m 20 m 31 m ? m Find the area and perimeter of Johns new backyard

41 41 38 m 18 m 24 m 20 m 31 m 7 m Perimeter = = 158 m AREA = 38 x 24 = 912 m² AREA = 20 x 7 = 140 m² TOTAL AREA = 1052 m²

42 42 John wanted to fill a rectangle prism with sand for a paper weight. What is the volume of the container? h = 5 mm l = 3 mm w = 2 mm Volume = l w h

43 43 Volume = l x w x h = 3 x 2 x 5 = 30 mm³ h = 5 mm l = 3 mm w = 2 mm

44 44 John wanted to create a dog pen that is 20 m³. What are some of the possible dimensions of his dog pen? b = ? m h = ? m

45 45 Possible dimensions for an area of 20 m³: 1 x 2020 x 1 2 x 1010 x 2 4 x 55 x 4 b = ? m h = ? m

46 46 John wanted to make a picture frame that has a perimeter of 40 inches. If John wanted to make a square frame, what would the dimensions of the frame be?

47 47 Since a square has 4 congruent sides all the lengths of the sides must be the same length. So divide the perimeter by 4 to get the length of each side. 40 ÷ 4 = 10 in So each side would measure 10 inches 10 in

48 48 John wanted to ship a gift to his sister in California. The volume of the gift is 30 in³. Will the box he bought be the right size for the gift? h = 2 in l = 12 in w = 2 in

49 49 h = 2 in l = 12 in w = 2 in Volume = l x w x h = 12 x 2 x 2 = 48 in³ Since the gift is 30 m³ and the box is 48 m³. The gift should fit in the box, because the volume of the gift is smaller than the box!

50 50 Karen has rock that measures l = 50 cm, w = 8 cm and h = 20 cm. What is the volume of the following rock? Will the rock fit in a container that has a volume of 7500 cm³?

51 51 If the rock measures l = 50 cm, w = 8 cm and h = 20 cm. Volume of Rock = l x w h 50 x 8 x cm³ The rock will not fit into the container because the volume of the rock is larger than the container, 7500 cm³?
