Purpose: Students use segments and angles to trace and describe paths for a turtle. Materials: Ruler, protractor, unlined paper, and a plastic turtle, bear, or other "creature" to help with perspective Part A: Drawing the Path of a Turtle Each of the following paths indicates the movements of an imaginary turtle. Trace the path of the turtle on a sheet of unlined paper. Begin by placing a starting point near the center of the paper and marking it with START. Use a ruler and protractor to draw the path of the turtle. Mark the ending point of the path with STOP. Path 1 Forward 3 cm Right 90° Forward 2 cm Right 45° Forward 5 cm Path 3 Forward 3 cm Right 120° Forward 7 cm Left 90° Forward 6 cm Path 2 Forward 4 cm Left 45° Forward 5 cm Right 90° Forward 6 cm Path 4 Forward 2 in. Right 90° Forward in. Left 50° Forward 2-in. 4 Right 130⁰ Forward 1-in.
Part B: Describing the Path of a Turtle 1. a. Write a set of directions that will guide a turtle along the following path if he begins at point 4, faces the top of the page, and travels in a clockwise direction. Use the given lengths. b. Write a set of directions that will guide a turtle along the following path if he begins at point B, faces the left side of the page, and travels in a counterclockwise direction. Use the given lengths. 3 in. 2 in. 4 in. 2 in. 3 in. 5 in. 7 in. 2. Write a set of directions that will guide a turtle along the following path if he begins at point C, faces the top of the page, and travels in a counter clockwise direction. Use the given lengths and angle measures. 8 in. B 135 5 mm. 45°
