TEKS 5.8B Worksheets — Grade 5 Describe the process for graphing ordered pairs

Isabella is helping her family on their ranch in Texas. They have 3 fields for planting crops. The first field has 12 rows of cotton plants, the second field has 15 rows, and the third field has 9 rows. How many rows of cotton plants do they have in total?

1. 36 ✓
2. 30
3. 27
4. 24

Why: To find the total number of rows of cotton plants, add the number of rows in each field together: 12 + 15 + 9 = 36. Therefore, the total number of rows of cotton plants is 36.

Lucia is helping her family at their peach orchard in Central Texas. They need to mark points on a coordinate grid to show where they planted different peach tree varieties. The first variety is planted at the point (4, 3). If they plant another variety 2 units to the right and 1 unit up from the first point, what will be the coordinates of the second variety?

1. (6, 4) ✓
2. (4, 5)
3. (5, 3)
4. (3, 2)

Why: To find the new coordinates, start at (4, 3) and move 2 units to the right, which adds 2 to the x-coordinate, giving you 4 + 2 = 6. Then, move 1 unit up, which adds 1 to the y-coordinate, giving you 3 + 1 = 4. Therefore, the new coordinates are (6, 4).

Riley is visiting the San Antonio River Walk with her family. They plan to eat lunch at a restaurant located at the point (4, 5) on the coordinate grid of the area. If they are currently at the point (4, 2), which direction do they need to move to reach the restaurant?

1. up ✓
2. down
3. left
4. right

Why: To reach the restaurant at the point (4, 5) from their current location at (4, 2), Riley and her family need to move up. The y-coordinate increases from 2 to 5, which means they are moving upward along the vertical axis.

Paola is visiting the San Antonio River Walk. She wants to take a boat ride that costs $15 per person. If she takes 3 friends with her, what is the total cost for all four of them to go on the boat ride?

1. $45
2. $60 ✓
3. $30
4. $75

Why: To find the total cost for all four people, multiply the cost per person ($15) by the number of people (4). So, 15 × 4 = 60. Therefore, the total cost for the boat ride is $60.

Aisha is visiting Big Bend National Park and is creating a map of the park using a coordinate plane. She has plotted the first point of her map, Point A, at (4, 5). If she wants to plot the next point, Point B, at (4, 8), what are the coordinates Aisha will use for Point B?

1. (4, 8) ✓
2. (8, 4)
3. (5, 4)
4. (5, 8)

Why: To find the coordinates for Point B, Aisha must keep the x-coordinate the same as Point A, which is 4, and change the y-coordinate to 8. Therefore, the correct coordinates for Point B are (4, 8). This represents a vertical movement up from Point A on the coordinate plane.

Malik is organizing a science fair at his school in Houston, Texas. He wants to plot the number of projects submitted by each grade level on a coordinate plane. The 5th-grade class submitted 12 projects and the 6th-grade class submitted 15 projects. If we represent the 5th-grade class on the x-axis and the 6th-grade class on the y-axis, which ordered pair would correctly represent the number of projects submitted by both grades?

1. (12, 15) ✓
2. (15, 12)
3. (12, 12)
4. (15, 15)

Why: To represent the number of projects submitted by each grade level on a coordinate plane, we use ordered pairs where the first number corresponds to the 5th-grade class and the second number corresponds to the 6th-grade class. Since the 5th-grade class submitted 12 projects and the 6th-grade class submitted 15 projects, the correct ordered pair is (12, 15). This means we plot the point where 12 is on the x-axis and 15 is on the y-axis.

Emma is organizing a bake sale to raise money for her school's science fair in Houston, Texas. She baked 24 cookies and plans to put them into boxes. If each box can hold 6 cookies, how many boxes will Emma need to hold all the cookies?

1. 4 ✓
2. 5
3. 6
4. 3

Why: To find out how many boxes Emma needs, divide the total number of cookies by the number of cookies each box can hold. So, 24 ÷ 6 = 4. Therefore, Emma needs 4 boxes to hold all the cookies.

Hana is creating a coordinate grid to map her favorite fruits at the San Antonio Stock Show. She wants to plot the location of oranges at (4, 3) and limes at (2, 5). Where would the point representing limes be located on the grid?

1. (2, 5) ✓
2. (5, 2)
3. (3, 4)
4. (4, 2)

Why: To find the location of limes on the coordinate grid, we look at the ordered pair (2, 5). This means the point is located 2 units to the right and 5 units up from the origin. Therefore, the correct answer is (2, 5).
