3 8 cm. The isosceles triangle pictured to the left has a total perimeter of 20 centimeters. This is the distance of the bottom segment, which is marked x. x

4 What is 4 centimeters?

5 Of the following expressions, this is the one that could be used to find the area of the figure to the left. A.4 + 4 + 4 + 4 B.5 + 5 + 4 + 4 C.5 x 4 D.5 x 5 x 4 x 4 = 1 square unit

6 What is C. 5 x 4?

A.The area of his walls added together. B.The height of the ceiling. C.The volume of the room. D.The perimeter of his room

8 What is D. The perimeter of his room?

9 A parallelogram is shown on the grid below: This expression represents the area of the parallelogram: A. 6 + 6 + 4 + 4 B. 8 + 8 + 4 + 4 C. 6 x 4 D. 8 x 4

10 What is D. 8 x 4?

11 The right isosceles triangle pictured to the left has dimensions as shown. This is the area of the triangle. 10 cm.

12 What is 50 square centimeters? Explanation: To find the area of a triangle, you need to multiply the base (10 cm. ) by the height (10 cm.) and then divide by 2.

13 Type of Ice CreamNumber of Votes Vanilla Chocolate Strawberry Mint Chelsea asked the students in her room which type of ice cream they liked. The above graphic shows the results. Of the following, this is what Chelsea used to show her data. A.Bar Graph B.Frequency Table C.Line Graph D.Histogram

14 What is B. Frequency Table?

15 SeasonNumber of Votes Fall10 Winter12 Spring18 Summer60 Bob surveyed 100 classmates to find out their favorite season of the year. The data is in the table at the top of this slide. He then created a circle graph using the same data, but forgot to label the different areas. According to the information given, this is season represented by the blue part of the pie chart.

16 What is Spring?

17 Number of Leighton Students Who Bought Ice Cream at Lunch on Monday According to the bar graph, this is the mean number of girls in each grade level that bought ice cream on Monday.

18 What is 30 girls? Explanation: The mean is another word for average. According to the graph, 30 3 rd grade girls, 35 4 th grade girls, and 25 5 th grade girls bought ice cream on Monday. To find the average, you need to find the sum of the three numbers, which is 90, and then divide by 3, since there are three numbers.

19 Mrs. Lambacher collected data from the school in the canned food drive. She wanted to find out which grade brought in the most canned food and what the percentages were. After looking at the data, she made the circle graph below. However, she forgot to fill in the percentage for the 5 th graders. This is the percent she should have filled in.

20 What is 55%?

21 The graph below shows annual sales at Bernie’s Bakery during its first four years of business. Of the choices below, this is the best prediction for the annual sales in 2004. A. $80,000 B. $90,000 C.$100,000 D.$120,000

22 What is C. $100,000?

23 Every day on his way to work, Bill stops at the doughnut shop and gets two doughnuts and one large cup of coffee. One doughnut costs $0.99 and a cup of large coffee costs $2.09. This is about how much money Bill spends after 30 trips to the coffee shop.

24 What is $120? Explanation: Bill spends about $4 each day at the doughnut shop. 4 x 30 = 120

25 Maddie measured the length and width of the rectangle above. She said the length of the rectangle was 2 1/8 inches long. The width of the rectangle was 1 1/4 inches long. This is the total perimeter of the rectangle.

26 What is 6 ¾ inches?

27 Four different fifth grade girls decided to sell candy bars to raise money for the homeless. Their goal was to sell a total of 1000 candy bars. Mary sold 237 candy bars, Liz sold 293 candy bars, and Jackie sold 268 candy bars. How many bars does the fourth girl, Lucy, have to sell in order to reach their group goal?

28 What is 202 candy bars?

29 There are 6,965 library books spread out over 70 different shelves in a library. If each shelf has about the same number of books, this is a reasonable estimate for how many books are on each shelf.

30 What is 100 books?

31 The Smith family went on a family vacation. It took them 4 days to get to their destination by car, which was 1,003 miles away. This is the about the average number of miles they had to drive each day to arrive at their destination.

32 What is 250 miles?

33 Sam drew a triangle and measured each of the angles. He said one angle measured 90 degrees, one angle measured 40 degrees and the third angle measured 60 degrees. His friend, Tony, said those measurements weren’t possible. This is the reason Tony said that.

34 What is Those 3 angles total 190 degrees, but the sum of all the angles in any triangle has to be exactly 180 degrees?

35 This is the sum of all the angle measurements in the figure shown below.

36 What is 360 degrees? Explanation: The sum of all the angles in any quadrilateral is always 360 degrees.

37 Joan has two gardens in her yard. One garden is in the shape of a circle and has a diameter of 5 feet. The other garden is in the shape of a square and the length of one side of the square is 5 feet. Joan wants to put fencing around both gardens. This is about how much fencing Joan will need.

38 What is Joan needs about 35 feet? Explanation: To find the amount of fencing Joan needs for the circle, you need to know its circumference. To find about what the circumference is, you need to multiply the diameter by 3, so the circumference is about 15 feet. To find the amount of fencing for the square, you need to find its perimeter. Since one side of the square is 5 feet, its perimeter is 20 feet. 15 feet + 20 feet = 35 feet

39 Of the four shapes pictured below, these are the two that appear to be congruent to each other. A.B. C. D.

40 What is Shapes A and B? Explanation: Congruent means two shapes that have the same size and shape. Even though shape B has been rotated slightly, it is still the same size and shape as shape A.

41 The two lines pictured above cross at a 90 degree, or right angle. This is the word that means crossing at a 90 degree angle.

42 What is perpendicular?

43 This is the median number of the following: 0.341/3 3/80.3 2/5

44 What is the 0.34? Explanation: The median is the middle number in a set of data after the numbers have been put in order. The numbers in order are 0.3 1/3 0.34 3/8 2/5 so the middle number is 0.34

45 Ten balls are placed in a bucket. The balls are numbered 1 – 10. Jill takes one ball out of the bucket. This is the probability, expressed as a percent, that the ball she takes out has a number on it that is a factor of 10.

46 What is 40% Explanation: The factors of 10 are 1, 2, 5, and 10. Since 4 of the balls are factors of 10 and there are 10 balls, she has a 40% chance.

47 Bill is at a party and needs to make a sandwich. There are two different kinds of bread that he can choose from – wheat or rye. There are three different types of meat he can choose from – bologna, ham, or turkey. There are three different types of cheese he can choose from – Swiss, American, or cheddar. Bill can only make one choice from each category. This is the number of different types of sandwiches Bill could actually make.

48 What is 18 different types of sandwiches? Explanation: There are 2 different types of bread, 3 different types of meat, and 3 different types of cheese. To find the total number of combinations, you multiply those three numbers together. (2 x 3 x 3 = 18)

49 20 – 2 3 x 2 + 3 = This is the answer to the problem below:

50 What is 7?

51 A spinner is divided into 5 equal sections. The sections are numbered 1, 2, 3, 4, and 5. Sally spins the spinner 100 times. According to theoretical probability, this is how many times out of the 100 spins, Sally should get a prime number.

52 What is 60 spins? Explanation: A prime number is a number that has exactly 2 factors. 2, 3, and 5 are all prime numbers. According to theoretical probability, Sally should get each number 20 times. Since there are three prime numbers, she should spin a prime number a total of 60 times.
