About these worksheets
These worksheets introduce students to the concept of variables and algebraic thinking. Activities include using substitution to evaluate expressions, writing and graphing inequalities on a number line, identifying numerical coefficients, solving for unknown values using all four operations, and exploring powers, bases, and slope. Aligned with sixth through eighth grade standards, these resources build the foundation for pre-algebra and algebra.
Examining Slope Attributes
- Find the slope of a line by comparing the rise and run shown with two triangles on a graph.
- Compare two slopes to tell which line is steeper and explain why using rise/run.
- Write slope as a ratio or fraction and simplify it when possible.
Comparing Approximate Measurement with Charts and Tables
- Read measurement values from a chart and from a table.
- Compare two measurements and decide which is larger or smaller.
- Use the scale and units shown to interpret approximate measurements correctly.
Comparing Measurement with Tables and Equations
- Practice finding a unit rate from a table and comparing it to a rate given as an equation
- Determine which of two companies offers a better deal (fewer pieces per box or higher cost per pound)
- Use an equation like y = 30x to calculate a total for a specific number of units
- Compare proportional relationships when the information is shown in different formats (tables vs. equations)
