## Reflection: Pacing Predicting Water Park Attendance - Section 2: Investigation

This lesson went much better than I anticipated with this particular class!  A few things I did that seemed to help our process:

• We talked about making a prediction based on the table, and students were quick to point out that a graph would be a valuable way for us to visualize this information.
• Students did not balk at graphing a lot of data points, this was something I was worried about given the stamina of my current class.
• Once everyone had at least one graph finished, we talked about line of best fit using the SmartBoard to have a student move a straight line around to find the best place to put it. Students had a great discussion about whether or not the line of best fit should go through the origin.

# Predicting Water Park Attendance

Unit 2: Multiple Representations: Situations, Tables, Graphs, and Equations
Lesson 8 of 17

## Big Idea: From scatterplot to predictions. Students plot data, approximate a line of best fit, generate an equation for the line to make predictions.
