One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

The concept of absolute value can be difficult for learners to grasp. Reinforce their understanding of a basic absolute value expression and connect it to solving equations and inequalities. Scholars write two equations/inequalities to...

What is the net effect when two waves interfere with each other? The lesson plan answers this question by helping the class visualize waves through graphing. Pupils graph individual waves and determine the effect of the interference...

Create an understanding of solving problems that require more than one equation. The lesson introduces the concept of systems of linear equations by using a familiar situation of constant rate problems. Pupils compare the graphs of...

Students explore hurricanes.  In this weather data interpretation lesson, students draw conclusions about the impact of Hurricane Floyd as it related to weather conditions. Students read and interpret a tide data table, a barometric...

What did some Pilgrims wear on top of their heads? Individuals graph sets of ordered pairs, and connect the points to create a mystery Thanksgiving picture.

A chart with eight rows makes up this handout. The columns are labeled with two graphs ("x vs. t" and "v vs. t"), a written description, and a motion map. One cell in each row is filled in, leaving the rest for your class to complete....

Line up the temperature conversions. Pupils create the linear function between Celsius and Fahrenheit on a graph by plotting the freezing and boiling points of water. The scholars determine how the relationship changes based upon...

Dig into a classic math problem with your classes. Through an engaging task, learners work with rate and distance information to make conclusions. In the task, two people walk at different rates; one leaves first, and scholars...

Students determine how the slope affects the graph of a line. They relate "b" to the "y"-intercept of a line and solve the equation of a line given "m" and "b." They are given scenarios and possible answers to which they explain why or...

In this graphing worksheet, 9th graders read one page of graphing examples and complete 8 exercise problems. Each problem involves graphing and coordinates.

Students make mathematical argument using the concept of Limit. In this algebra instructional activity, student calculate the instantaneous rate of change from the linear graph. They use a TI-calculator to create a visual of the graphs.

Students produce a graph of favorite colors.  For this graphing lesson, students create a human graph based on their favorite color then the teacher transfers the data to a bar graph.  Students compare the lines on the graph...

In this graphs and equations of lines worksheet, 10th graders solve 12 different problems that include graphs and various equations of lines. First, they determine the slope of a line that passes through two sets of points. Then,...

Students work in pairs to test the strength of spaghetti strands. They collect and graph data to determine a line of best fit. Students create a linear equation to interpret their data. Based on the data collected, students predict...

In this scatter plot worksheet, students examine tables and write a linear equation that matches the table.  Students graph linear equations.  They read scatter plots, determine the trend line, and write a linear equation to...

Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.

In this graphs worksheet, students find the mid-point of a line and identify its coordinates. This six-page worksheet contains 7 multi-step problems. Explanations and examples are provided. Answers are located on the last page.

Fourth graders examine the use of stem and leaf graphs. In this stem and leaf graph lesson, 4th graders participate in teacher led lesson showing the use of the graphs. They work in groups to collect data about peanuts before making a...

In this algebra/geometry worksheet, students investigate the slopes and equations of parallel and perpendicular lines.  The two page worksheet contains a combination of eleven multiple choice and free response questions. ...

In this Algebra I/Algebra II activity, students examine slope to determine if the given lines are parallel or perpendicular.  Students determine the equation of lines that are either parallel or perpendicular to the given...

Students differentiate between parallel and perpendicular lines. In this algebra activity, students graph linear equations using the slope intercept form. They classify lines based on their slopes.

In this linear equations worksheet, students write the equation of a line with given characteristics. They identify the slope of a line and the y-intercept. Explanations and examples are provided at the beginning of the worksheet. This...

Math masters are introduced to graphing inequalities on a number line. After reviewing inequality symbols, they practice representing them on a worksheet. This simple lesson serves its purpose.
