This document provides an agenda and lesson objectives for a class on interpreting graphs. The agenda includes warm up, notes, examples, practice, and a formative assessment. The bell ringer asks students to determine if scenarios involving a person walking to the store are best represented by graphs with positive, negative, or zero slope. The objective is to learn to relate graphs to situations involving speed over time, time and distance, or speed and distance. An example graph shows a horse's varying speeds during exercise. Students are asked which graph best represents a tree's height increasing over time but not at a constant rate. The document ends with a reminder about an upcoming quiz.

Bell Ringer • Alessia walked to the store to buy some groceries. Tell whether her position in each story is best represented by a line with positive, negative, or zero slope. • 1. Alessia stopped to tie her shoe. • 2. Alessia walked from home to the store. • 3. Alessia ran home from the store.
Objective • Learn to relate graphs to situations
• You can use a graph to show the relationship between speed and time, time and distance, or speed and distance.
0 Speed (mi/hr) • The graph at the right shows the varying speeds at which Emma exercises her horse. The horse 20 walks at a constant speed for the first 10 minutes. Its speed increases over the next 7 minutes, and then it gallops at a constant10 rate for 20 minutes. Then 1 0 2 0 3 0 4 0 • it slows down over the next 3 minutes and • then walks at a constant pace for 10 minutes. 5 0 Time (min)
. The height of a tree increases over time, but not at a constant rate. Which graph bests shows this? As the tree grows, its height increases and then reaches its maximum height. Graph A shows the height of a tree not increasing but remaining constant. Graph C shows the height of a tree increasing at a constant rate without reaching a maximum height. The answer is graph B.
