Evaluate Relations with Scatter Plots: Regression and Correlation
Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...
Curated OER
Positively Negative?
Students practice the addition, subtraction, multiplication, and division of integers. They view a video clip on addition and subtraction of integers. Students observe a Web site that reviews multiplication and division of integers....
Curated OER
Making a Brain: Aritifical Neural Network
Students explore how the brain works. In this nervous system lesson, students create a network of "neurons" to simulate how the nervous system and the brain work together.
Curated OER
Eliminate What?
Students are introduced to the elimination method in Algebra. As a class, they solve two linear equations with two unknowns using this new method. They discuss the positive and negative aspects of using this method to solve problems. ...
Curated OER
Visual Communication of Quantative Data
Students collect and analyze data based on academic performance. In this statistics instructional activity, students create graphs and analyze the data they created. They use positive, negative and no correlation to analyze the data.
Curated OER
Exploring Quadratic Graphs
Students solve quadratic equations using graphs. In this algebra lesson, students factor quadratic equations and graph their answer. They discuss the shape of their graph based on the function.
