TEKS 5.9B Worksheets — Grade 5 Represent discrete paired data on a scatterplot

Emma is planting orange trees in her backyard in McAllen, Texas. She has 4 rows of trees, with 6 trees in each row. After planting, she decided to add 3 more trees to each row. How many trees will Emma have in total after adding the new trees?

1. 36 ✓
2. 30
3. 24
4. 40

Why: First, calculate the initial number of trees: 4 rows * 6 trees per row = 24 trees. Then, for the additional trees: 3 more trees per row * 4 rows = 12 additional trees. Finally, add the initial amount to the additional amount: 24 + 12 = 36 trees in total.

Valentina is helping her family at their peach orchard in Central Texas. They collected data on how many peaches they harvested each week over four weeks. Here are the numbers: Week 1: 150 peaches, Week 2: 200 peaches, Week 3: 175 peaches, Week 4: 225 peaches. If Valentina was to plot these pairs of weeks and their corresponding peach harvests on a scatterplot, which point represents the harvest in Week 3?

1. (3, 175) ✓
2. (175, 3)
3. (3, 200)
4. (200, 3)

Why: To find the point that represents the harvest in Week 3, look for the coordinates that match week and peaches. Week 3 corresponds to 175 peaches, so the correct point is (3, 175).

Logan is collecting data on the number of visitors to Enchanted Rock each month. He recorded the following data for the first three months: January - 120 visitors, February - 150 visitors, and March - 180 visitors. Which scatterplot best represents the relationship between the month and the number of visitors?

1. A scatterplot that shows a line going upward from left to right. ✓
2. A scatterplot that shows a downward sloping line.
3. A scatterplot that shows points scattered randomly.
4. A scatterplot that shows a horizontal line.

Why: The correct answer is the first choice because the data shows an increasing trend in the number of visitors over the months. As the month progresses from January to March, the number of visitors increases from 120 to 180. Therefore, a scatterplot with a line going upward from left to right accurately represents this positive relationship.

Scarlett is collecting data about the number of different types of trees in the Piney Woods of Texas. She recorded the following data in a table: In Section A, there are 30 pine trees; in Section B, there are 40 pine trees; in Section C, there are 50 pine trees; and in Section D, there are 60 pine trees. Which scatterplot best represents the trend of trees from Section A to Section D?

1. The points show an upward trend from left to right. ✓
2. The points show a downward trend from left to right.
3. The points are scattered with no clear trend.
4. The points show a sideways trend from left to right.

Why: The correct choice is the first one. As you look at the number of trees from Section A to Section D, they are increasing consistently: 30, 40, 50, and then 60 pine trees. This represents an upward trend on a scatterplot, where the points move higher as you go from left to right.

Henry is organizing a bake sale at his school in Dallas, Texas. He collects data on the number of cookies sold each day for four days. The table below shows the number of cookies sold: Day 1: 12 cookies, Day 2: 15 cookies, Day 3: 10 cookies, Day 4: 18 cookies. How many cookies did Henry sell in total over the four days?

1. 55 ✓
2. 50
3. 45
4. 60

Why: To find the total number of cookies sold, add the number of cookies sold each day: 12 + 15 + 10 + 18 = 55. Therefore, Henry sold a total of 55 cookies over the four days.

Fatima is organizing a school trip to Enchanted Rock. Her class is planning to hike and picnic there. There are 25 students going on the trip, and each student will bring 3 sandwiches. How many sandwiches will Fatima's class bring in total?

1. 75 ✓
2. 80
3. 85
4. 90

Why: To find the total number of sandwiches, multiply the number of students by the number of sandwiches each student brings. So, 25 students * 3 sandwiches = 75 sandwiches. Therefore, the correct answer is 75.

Valentina is studying the number of oranges harvested from different farms in the Rio Grande Valley. The table shows the number of oranges (in hundreds) harvested from each farm: Farm 1 - 8, Farm 2 - 12, Farm 3 - 15, and Farm 4 - 10. Which point on the scatterplot best represents the number of oranges harvested from Farm 2?

1. (2, 12) ✓
2. (2, 1200)
3. (1, 12)
4. (4, 10)

Why: To find the point that represents the number of oranges harvested from Farm 2, we look at the data. Farm 2 harvested 12 hundreds of oranges, which can be represented as (2, 12) on the scatterplot. The x-coordinate is 2 (for Farm 2), and the y-coordinate is 12. Therefore, the correct answer is (2, 12).

Cristian went to a local farmers' market in West, Texas, where he bought a total of 30 pounds of vegetables. He purchased 12 pounds of tomatoes, 10 pounds of cucumbers, and the rest were bell peppers. How many pounds of bell peppers did Cristian buy?

1. 8 ✓
2. 10
3. 12
4. 18

Why: To find out how many pounds of bell peppers Cristian bought, we first add the weights of the tomatoes and cucumbers: 12 + 10 = 22 pounds. Then, we subtract this from the total weight of the vegetables: 30 - 22 = 8 pounds. Therefore, Cristian bought 8 pounds of bell peppers.
