Middle schoolers recognize dependent and independent variables in an experiment by practicing manipulation of variables; students practice designing experiments that contain the two types of variables.

Graph linear equations using a table of values. Learners solve equations in two variables using standard form of an equation. They identify the relationship between x and y values.

Use the constant of proportionality to relate the independent variable to the dependent variable. The eighth installment of a 22-part series instructs pupils to use the equation to find the constant of proportionality and then write the...

Learners collect and analyze data. In this statistics instructional activity, pupils create a liner model of their data and analyze it using central tendencies. They find the linear regression using a spreadsheet.
