Curated OER
Sums of 3, 4, and 5
In this basic mathematics instructional activity, students add each of the colored buttons to get their answer. They use addition to solve each of the 16 problems on the sheet.
Curated OER
Point-Slope Form
Ninth graders explore the point-slope form of linear equations and graph lines in the point-slope form. After completing the point-slope equation, they identify the slope of a line through a particular point. Students explain the...
Curated OER
Introducing Linear Terminology
Ninth graders graph linear equations and inequalities in two variables and then, they write equations of lines and find and use the slope and y-intercept
of lines. They use linear equations to model real data and define to define the...
Curated OER
Standard Linear Form
Ninth graders identify and describe the x-intercept as the place where the line crosses the x-axis as it applies to football. They create their own differentiations to reinforce the distinction between the x-intercept and the...
Curated OER
Sloping and Intersecting a Linear Function
Students examine and discuss typical linear equations, and the difference between a linear and nonlinear equation. They observe examples of linear equations and complete a worksheet.
Curated OER
A Shortcut for Multiplying Large Numbers
In this multiplying large numbers worksheet, students read about a shortcut to use when numbers have zeros and are large. They learn to remove the zeros and multiply the non-zero numbers and then add the total number of zeros. They...
