solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP4.
Model with mathematics.
MP5.
Use appropriate tools strategically.

MP7.
Look for and make use of structure.

Student groups create Rain Forest Trails models using two perpendicular axes with Mr. Origin at the origin. The groups exchange models and use direction and distance to describe the locations of animals plotted along the axes on the models. Students create maps of the models and compare the two representations. Finally, they use the maps and data tables to solve problems involving length.

Content in this Lesson

  • Describing the location of objects relative to an origin using directions (left, right, front, back) and distance on perpendicular axes [E3].
  • Locating objects on a map using directions (left, right, front, back) and
    distance [E3].
  • Measuring length in centimeters [E4].
  • Making a table to find information about a data set [E5].
  • Reading a table to find information about a data set [E6].
  • Using a table to solve problems about a data set [E7].
  • Solving word problems (e.g., compare) involving length.
  • Using labels like centimeters and meters to show what numbers
    mean [MPE6].

Materials Preparation

Prepare Rain Forest Animals. Cut copies of the Rain Forest Animals Master in half so that each group will receive a set of six animals and you will have one example set.

Prepare Grids and Keys for Rain Forest Trails Models. Tape two pieces of masking tape at least 40 centimeters in length perpendicular to one another on large sheets of chart paper. See Figure 1. Make one grid for each student group. Include one copy of the Key for Rain Forest Trails Master, one set of rain forest animals, and a prepared Mr. Origin. Label each model and each key with a model number (for example, Model 1–6 if you have 6 groups). Also prepare one grid for a demonstration model.

Prepare Display of Rain Forest Trails Model. Create one complete model of the same grid with Mr. Origin at the center (origin) where the two axes intersect. Use the prepared set of rain forest animals and the key in the table in Figure 2.
