# Quantitative Relationships

\$0.00

Your students already understand how to measure and collect data, and now they need to learn how to work with that data. The lesson discusses dependent and independent variables and how they relate. Students also work on creating graphs using their collected data. Several examples and activity sheets are included with the lesson. Independent practice sheets, suggested homework assignments, and a quiz to use for assessment are included with the lesson. The lesson will be most effective when used in conjunction with other lessons related to data collection and graphing.

## Quantitative Relationships Lesson Plan Includes:

• Full Teacher Guidelines with Creative Teaching Ideas
• Instructional Content Pages about Quantitative Relationships
• Hands-on homework activities giving students practice on comparing and contrasting Quantitative Relationships
• Common Core State Standards

### Description

The lesson discusses dependent and independent variables and how they relate.  Students are reminded that quantitative means the ability to measure an amount, and two variables together can represent relationships between amounts.  During the lesson, students will work on creating graphs using their collected data.  The lesson will be most effective when used in conjunction with other lessons related to data collection and graphing.

Sample classroom Procedures:

1. Begin by explaining to students that in order to conduct mathematical research, scientists must be able to understand what they are measuring and the must be able to take the collected data and transform it into equations, tables, and graphs.
2. While reading the content pages, reinforce vocabulary and give students additional examples of problems in order to help them practice finding the independent and dependent variables.  Use the additional resources to enhance understanding.
3. Introduce the notes on quantitative relationships. Have students practice problems as a group by walking through each of the steps.  Use the additional resources to enhance understanding.
4. Have students practice problems by explaining their choices and reasoning.
5. Follow Activity page with students. Have students work in pairs.  Provide each pair with a measuring device and a tennis ball.
6. Distribute Practice page. Check and review the students’ responses as a class.
7. Distribute the Homework page. Go over homework at the beginning of the next class to reinforce concepts.
8. In closing, ask students to talk about the data they collected during the experiment.
9. Allow for responses and discussion.
