NAME: ______Grade 5 5.OA.A.2

Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 x (8 + 7). Recognize that 3 x (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product. Problem 1: The Expo Line The new Expo Line extends the railway line from Culver City to Santa Monica. There are 7 new stations (see photo below) from Downtown Santa Monica to Culver City.

Use the map above, what you know about the Expo Line, and your knowledge of mathematical expressions to write an expression that represents the story below. a. Jose took the Expo Line from Downtown Santa Monica to Westwood/Rancho Park so he could go to the movie theater. That ride took 11 minutes. When he got off the train, he walked 6 minutes to the movie theater, where he waited for 10 minutes, for his friend who was coming from downtown LA. Once his friend arrived, they got their tickets and watched the movie, which took 103 minutes in all. Jose invited his friend to sleepover at his house and they walked back to Westwood/Rancho Park station and took the 11 minute ride back to the Downtown Santa Monica station. Write an expression that represents the amount of time from the moment Jose left the Santa Monica station to when he returned.

b. Write your own story about the Expo Line and an expression with at least 3 numbers that represents that story. Think of measuring things in minutes, the number of stops, or distance. Use a set of parentheses at least once in your expression. 2

Problem 2: Counting the Metro Passengers Sarah decided to play a game based on her observations of the passengers on the Expo Line. When she got on the Expo Line at the 26th St./Bergamont station, she noticed that there were 38 people in the car. At Expo/Bundy, 13 more passengers got on the train, and 4 passengers got off the train. At the next stop, Expo/Sepulveda, the number of passengers doubled. When the train arrived at Westwood/Rancho Park, another 10 passengers got on the train, while no passengers departed. Write an expression that represents the number of passengers on the train at the end of the ride.

*Challenge: When the train arrived at Palms station, the number of passengers on the train halved. How would you change the expression above to represent the number of passengers at Palms? Can you think of two ways to manipulate the expression? Math in My World: K-5 Common Core for Angeleno Students 3

Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule “Add 3” and the starting number 0, and given the rule “Add 6” and the starting number 0, generate terms in the resulting sequences, and observe that the terms in one sequence are twice the corresponding terms in the other sequence. Explain informally why this is so. Problem 1: Saturday and Sunday Bicycle Trip Anita is going on a bicycle trip this weekend and wants to see how biking a certain distance every hour will change the total number of miles she bicycles.

On Saturday, she decided to bicycle 4 miles every hour. In other words, she added 4 miles to her total trip for every hour that went by.

On Sunday, she decided to bicycle 8 miles every hour. In other words, she added 8 miles to her total trip for every hour that went by.

Apply the formulas V = l x w x h and V = B x h for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving real world and mathematical problems. Problem 2: Which One is right? The city of Santa Monica is installing new trees along Santa Monica Boulevard. The area of the sidewalk where they are installing the trees has a restriction where the base area for the tree cannot be larger than . However, the trees will need at least in volume in order to grow properly.

For each of the designs for the tree spaces below, help complete the design with the missing length, height, or width that would allow the tree to grow properly with a base area of no more than and a volume of at least . Round to the nearest whole number. This activity is appropriate for calculator use.

DESIGN 1 The tree space could have a length of 21 inches, width of ______inches, and height of 90 inches. What is a width that could work? Prove your answer below by solving for the volume and base with your suggestion.

DESIGN 2 The tree space could have a length of ______inches, width of 34 inches, and height of 88 inches. What is a length that could work? Prove your answer below by solving for the volume and base with your suggestion.

DESIGN 3 The tree space could have a length of 32 inches, width of ______inches, and height of 100 inches. What is a length that could work? Prove your answer below by solving for the volume and base with your suggestion.

Apply the formulas V = l x w x h and V = b x h for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving real world and mathematical problems. Problem 3: New Busses The Big Blue Bus is getting a new fleet of busses in 2017. Find the volume of each of the busses, and then pick which bus you think is the best model and say why, based on your opinion of what makes a great size bus.

1) Bus #1 has a length of 43 feet, width of 9 feet, and height of 20 feet. What is the volume of Bus #1?

2) Bus #2 is a double-decker bus that has two stories. Its length is 30 feet, width is 10 feet, and height is 38 feet. What is the volume of Bus #2?

3) Bus #3 fits 2 people per aisle and is very long. Its length is 80 feet, width is 7 feet, and height is 12 feet. What is the volume of Bus #3?

4) Bus #4 is like a large room where bus passengers can socialize easily. Its length is 44 feet, width is 23 feet, and height is 9 feet. What is the volume of Bus #4?

Which bus is the best model for the new Big Blue Bus fleet? Why? ______Math in My World: K-5 Common Core for Angeleno Students 33

Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate). Problem 1: Schools in Santa Monica In the problem below, the X-axis represents the direction from East to West and the Y-axis represents the direction from North to South.

The following is a list of schools and their coordinates in Santa Monica. Plot them on the graph. Edison Language Academy: (3, -2) John L.
