7Judy covered a rectangular shaped box with wrapping paper Judy covered a rectangular shaped box with wrapping paper. Of the following choices, this is what she covered of the box.Perimeter of the boxSurface Area of the boxVolume of the boxCircumference of the box
8B. Surface Area of the box? What isB. Surface Area of the box?Explanation: Surface area is the sum of all the areas of the sides. In this case, Judy is covering the outside faces of the box with wrapping paper, so she covered the surface area of the box.
9Mr. Brown is putting a fence around his yard so his dog cannot get out Mr. Brown is putting a fence around his yard so his dog cannot get out. Of the following measurements, this is a possible amount of fencing that he would buy:140 centimeters140 yards140 square yards140 cubic yards
10What isB yards?Explanation: Mr. Brown needs to know the length of the fence he needs, so his answer can’t be square yards (which is an answer for area) or cubic yards (which is an answer for volume). The only possible answers are 140 centimeters or 140 yards centimeters is much too short, so 140 yards has to be the answer.
11A fifth grade student at Leighton made the greatest Mother’s Day present possible.

12Note to students: This would be a great present!! What isB square centimeters?Explanation: To wrap the box, you need to know the area of each of the faces of the box. Area is always expressed using the word square.Note to students: This would be a great present!!
13This is the ordered pair where the blue dot is located on the coordinate grid to the left.
15Jill was drawing a rectangle on a coordinate grid Jill was drawing a rectangle on a coordinate grid. She put three of the points in the locations shown. This the coordinate where the fourth point needs to be.
19An ant needed to travel from one blue dot to the other blue dot in the grid that is shown. The ant could only travel on grid lines. If the distance between each grid line on the grid is 1 cm., this is the shortest distance the ant could travel.
21Sam drew the triangle in blue on the grid to the left Sam drew the triangle in blue on the grid to the left. If each square on the grid is 1 square centimeter, this is the area of the blue triangle.
22What is 6 square centimeters? Explanation: The base of the triangle is 3 centimeters and the height of the triangle is 4 centimeters. To find the area of a triangle, you need to multiply the base and the height, and then divide by 2.

27The figure to the left is a square. Julie put her finger on Point A The figure to the left is a square. Julie put her finger on Point A. She moved her finger from Point A to Point B to Point C to Point D. This is the percentage of the way she went around the figure.ABCD
2875% of the way around the figure? What is75% of the way around the figure?
29Look at the drawing above. This is the percentage of boxes that have a shape in them.
31Tony made a plate of cookies Tony made a plate of cookies. One fourth of the cookies were chocolate chip, 0.6 of the cookies were peanut butter, and the rest of the cookies were oatmeal. This is the percent of the cookies that were oatmeal.
33Alex has a spinner divided into 8 equal parts with the numbers 1 – 8 on each part. He spins the spinner one time. This is the probability, expressed as a percent, that he will spin a number that is a factor of 8.
34What is50%?Explanation: The numbers 1, 2, 4, and 8 are all factors of the number 8, so 4 of the 8 numbers are factors of 8 and 4 are not. So, Alex has a 50% chance of spinning a factor of 8.
35The spinner to the left is divided into 5 equal parts The spinner to the left is divided into 5 equal parts. The spinner is spun 1000 times. According to theoretical probability, this is the number of times it should land on the letter A.
36What is200 times?Explanation: According to theoretical probability, the spinner should land on each section the same number of times. So, if should land on each number 200 times since 200 x 5 = 1000.
37Mr. Linden wrote all the letters in his last name on 6 different pieces of paper. He then put the 6 pieces of paper in a paper bag and took 1 piece out at random. This is the probability, expressed as a lowest term fraction, that the letter he took out was the letter ‘n’.
38What is1/3?Explanation: The word LINDEN has six letters, but two of them are the letter N.2/6 in lowest terms is 1/3.
39Of the following choices, this is the number of possible outcomes in the above situation. 26812
40What isD. 12?Explanation: To find the number of possible combinations, you need to multiply the number of choices for each. The coin can land on heads or tails, so that is two choices. The cube has six different possible choices. 6 x 2 = 12.
41Andy has 20 marbles in a bag Andy has 20 marbles in a bag. 10 of them are red, eight are black, and the rest are blue. Andy plans to take out a marble out of the bag, record its color, and then return the marble to the bag. He plans on doing this 10 times. According to theoretical probability, this is the number of times he should pull out a blue marble out of the 10 times.
42What is1 blue marble?Explanation: According to the information given, 2 out of the 20 marbles are blue, which is 10% of the marbles. If he is going to pull out 10 different marbles, that means that 10% of them should be blue, which is one marble.
