Lesson 1

Using Coordinates

Est. Class Sessions: 1–2

Summarizing the Lesson

Direct students to the Find the Panda pages in the Student Activity Book. In this game students will practice using coordinates and writing ordered pairs. The vignette establishes the context for this game. After reading the directions, use the example game and Questions 1–3 to make sure students understand how to play the game.

Question 1 asks students to decide if Julia's second guess is a good guess. Some students may not agree that it was a good guess because Julia only followed one of Chris's hints by just moving left, when she guessed (3,8). Other students may think her guess was good because now she knows the coordinate for the x-axis and only has to guess the coordinate for the y-axis.

Have students play the game with a partner.

  • How did the hints that the panda gave after each guess help you plan your next move? (Possible response: The hints helped me to decide the area of the map where I needed to make my next guess.)
  • How do ordered pairs help you find the location of an object on a map? (Possible response: The first number of the pair tells you how far to the right you have to go to find the object and the second number tells you how far forward you have to go.)

There are two sets of game boards in the Student Activity Book so that students can take one set of boards home to play the game with a family member. There is also a master for each game board in the Teacher Guide. Copies can be made of these game boards and placed in a center for students to use at another time.
