Developing the Lesson

Part 3: Solving Problems with Distance and Direction

As students finish their maps, ask them to work in their groups to answer Questions 3–7 in the Explore Rain Forest Data section of the Mapping Rain Forest Trails pages in their Student Activity Book. Ask each group to share their responses and strategies for answering the questions.

Upon completion, display the My Rain Forest Map Master. This map represents the data shown in Figures 2 and 3, and in your display. Pose additional addition and subtraction problems using these or similar questions.

  • Is the howler monkey in front of the spider monkey or in back of it? (It is in back of the spider monkey.) How did you decide? (Both the spider monkey and the howler monkey are in back of Mr. Origin. The spider monkey is closer to Mr. Origin, so the howler monkey is in back of the spider monkey.)
  • How far is the howler monkey from the spider monkey? (5 centimeters)
  • What strategy did you use to decide? (Possible response: I counted up spaces by twos and then counted on one: 6, 8, 10, 11.)
  • What is a number sentence that shows the distance between the howler monkey and the spider monkey? (6 + 5 = 11 or 11 − 6 = 5)
  • How far is the spider monkey from the armadillo? (23 centimeters)
  • Explain how you found the answer. (Possible response: I counted 6 centimeters to get to the origin and then counted another 17 centimeters to get to the armadillo.)
  • What number sentence shows how you found your answer? (Possible response: 6 + 17 = 23 centimeters)
  • John wrote the number sentence 7 + 8 = 15 centimeters to describe the distance between the turtle and the snake. What do each of the numbers in the number sentence mean? (The 7 describes how many centimeters the turtle is to the left of the origin. The 8 describes how many centimeters the snake is to the right of the origin. When you add seven to eight you get 15 centimeters to show the total distance between the turtle and the snake.)
  • If he stays on the trails, how far would the turtle have to go to get to the armadillo? (24 centimeters)
  • Explain how you found your answer. (Possible response: First the turtle would go 7 centimeters to get to the origin and then he would turn to the front and go 17 more centimeters. 7 + 17 = 24 centimeters.)

For additional practice, make displays of the maps completed by each group. Continue with similar questions that relate to the maps of different groups.
