About this worksheet

What students practice

Students read and write ordered pairs for points on a coordinate grid, including a grid that counts by 2s.
Students tell how far a point is from each axis using its x- and y-coordinates.
Students plot points from ordered pairs, starting at the origin each time.

How to use

Remind students that every trip starts at the origin: move along the x-axis first, then up. Point out that the chart in Part 2 counts by 2s before students begin.

Curriculum

Stargazing Camp: Star Charts and Ordered Pairs

Use the axes, the origin, and ordered pairs to find stars on a sky chart.

Part 1: The camp star chart

The campers drew this star chart. Each letter names a star. Use the chart to answer the questions.

Write the ordered pair for star A and for star B.

Star A is at ( , ).
Star B is at ( , ).

The ordered pairs for star A and star B use the same two numbers, 2 and 7. Why are the stars in different places?

A. The first number tells how far to move up, and the second number tells how far to move right.
B. They are not in different places, because (2, 7) and (7, 2) name the same point.
C. The first number tells how far to move right from the origin, and the second number tells how far to move up, so the order matters.
D. Star A is closer to the origin than star B is.

Star C is on the y-axis, and star D is on the x-axis.

What is the x-coordinate of star C?
What is the y-coordinate of star C?
What is the y-coordinate of star D?

Circle every star whose x-coordinate is greater than its y-coordinate.

star Astar Bstar Cstar Dstar Estar Fstar G

Look at star G.

How many units is star G from the x-axis? units
How many units is star G from the y-axis? units

Part 2: The telescope chart

The camp telescope shows a bigger part of the sky. On this chart, the grid lines count by 2s. Read the numbers on the axes carefully.

What is the ordered pair for star H?

A. (3, 7)
B. (6, 14)
C. (14, 6)
D. (7, 3)

Write the ordered pair for star J and for star L.

Star J is at ( , ).
Star L is at ( , ).

Write the letter of each star.

Which star is at (0, 10)? Star
Which star is on the x-axis? Star

A comet appears 8 units to the right of star H, at the same height as star H. What is the ordered pair for the comet?

The comet is at ( , ).

Part 3: Plot a constellation

Show what you know about the coordinate plane.

10.

Is each sentence true or false? Sort the sentences.

The origin is the point (0, 0), where the x-axis and the y-axis meet.The point (5, 0) is on the y-axis.(3, 8) and (8, 3) name the same point.The y-coordinate tells how far up from the x-axis a point is.Every point on the x-axis has a y-coordinate of 0.To plot (6, 1), start at the origin and move 6 units up.

True	False

11.

The campers found the Snake constellation. Plot and label its four stars: P at (1, 2), Q at (3, 5), R at (6, 4), and S at (8, 8). Then connect the stars in order from P to Q to R to S.
