Learners discover a method for determining the slope of a line by creating and comparing similar triangles. They fold coordinate grids to make three similar triangles then measure the sides to compare the relationships between the triangles. The slope equation or rise over run is developed from these relationships.
A hands-on instructional activity using the TI-CBR Motion Detector to provide information to graph and analyze. The class uses this information to calculate the slope of motion graphs and differentiate scalar and vector quantities. There is a real-world activity of a Roof Manufacturer's Test in regards to the pitch of roofs, as well as several other real-world scenarios.
Middle and high schoolers explore the concept of slope. In this slope lesson, learners graph lines using a life-size graph. They use chalk on a blacktop to create a coordinate plane and use each other as the tick marks on the grid. Pupils change the slope in relation to steepness and direction.
Mathematicians apply the formula for line slope to determine the slope of stairs in their school. They work in small groups to take the appropriate measurements, perform the necessary calculations, and find the mean of their group slope calculations. They discuss the reasons why the slope calculations may be different.
Practice the properties of lines in the coordinate plane. Young mathematicians use Cabri on their graphing calculator to determine the slope ratios. They use the change in y-coordinates/change in x-coordinates. Additionally, they find the equation of lines using slope and a y-intercept.
In this understanding slope worksheet, students solve 13 various problems that are related to determining the slope of a line. First, they calculate the rate of change by analyzing the differences in the x- and y-values. Then, students determine which grows at a faster rate and create a graph to represent their data found, identifying which line on the graph is steeper.
