Purpose

Students will engage in a hands-on exploration of slopes by collecting and analyzing real-world data. They will work collaboratively to create tables, graphs, and equations that represent this data, allowing them to identify and interpret slopes. Through this process, students will develop a deeper understanding of how slopes can be used to predict trends and make informed decisions in various contexts. This project encourages critical thinking and problem-solving skills, fostering a practical application of mathematical concepts in everyday life.

Learning goals

Students will explore how to find and interpret the slope from tables, graphs, and equations using real-world data sets. They will work in small groups to collect data from their surroundings, such as measuring the incline of a local hill or analyzing trends in weather patterns. By the end of the project, students will present their findings, demonstrating their ability to calculate and apply slopes to make predictions or decisions in practical scenarios.

Standards

Common Core - CCSS.MATH.CONTENT.8.EE.B.5: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.
Common Core - CCSS.MATH.CONTENT.8.F.B.4: Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values.
Common Core - CCSS.MATH.CONTENT.8.SP.A.1: Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities.

Products

Students will gather real-world data related to a topic of interest, such as local weather patterns or sports statistics. They will create tables, graphs, and equations to represent the data, identifying and analyzing slopes to predict future trends. By the end of the project, students will present their findings in a multimedia presentation, showcasing their ability to interpret and apply slope concepts in meaningful contexts.

Launch

Kick off the project by having students explore the concept of slope through a hands-on activity involving a real-world scenario, such as analyzing the incline of a local hill or ramp. Provide students with tools to measure the rise and run, and have them calculate the slope. Invite students to discuss how slopes affect activities like biking or construction, and encourage them to brainstorm other areas where understanding slope is crucial. This activity will set the stage for deeper exploration of slopes in tables, graphs, and equations throughout the week.

Exhibition

Students will gather and analyze real-world data, such as local weather patterns or sports statistics, to identify slopes and present their findings through a digital presentation or poster session. They will explain how the slopes they calculated can predict future trends or inform decision-making, using graphs, tables, and equations as evidence. The exhibition will be held in the classroom, inviting peers and teachers to engage with the students' work, ask questions, and provide feedback on their analysis and conclusions.

Plan

Week 1	Day 1
Activities	Slope Exploration Launch - Begin with a hands-on exploration of slope by measuring the incline of a local hill or ramp using available tools, and calculate the slope to understand its real-world implications. (20) Brainstorming Session - Discuss and brainstorm other areas in everyday life where understanding slope is important, such as biking or construction, to set the context for the project. (10) Introduction to Data Collection - Introduce students to various methods of collecting real-world data, such as measuring weather patterns or sports statistics, and decide on a data set for the project. (15) Group Formation and Planning - Form small groups and start planning how to collect and organize the chosen data, considering the necessary tools and steps involved. (15)
Deliverables	1. Completed data tables, graphs, and equations representing the collected real-world data, highlighting calculated slopes. 2. A multimedia presentation showcasing the analysis and interpretation of slopes in the chosen context.
Preparation	1. Gather measurement tools such as rulers, protractors, and calculators to facilitate data collection and slope calculations. 2. Provide graph paper, markers, and digital tools (such as tablets or computers) for creating graphs and tables. 3. Prepare examples of real-world contexts where slope is relevant, such as sports statistics, weather trends, or local geography. 4. Organize access to relevant digital resources or databases for data collection, like online weather data or sports statistics websites. 5. Set up a collaborative platform (such as Google Classroom or a shared drive) for students to share and store their work.
