Thirty-three problems present a variety of practice graphing a relation and checking to see if it is a function. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then...

Students can use a CBR 2 motion detector to measure distance and velocity. Students prepare graphs of motion and analyze them. They compare and match graphs of distance versus time and velocity versus time.

In this activity, students' will use a motion detector to record the distance versus time data for the simple motion of a walker. They will calculate velocity from this graph and compare it with the velocity graph generated by the...

WebMath offers a java applet that allows you to input the slope of a line and a point on the line and gives you the equation, in slope-intercept form, of the line with the given slope that passes through the point. It also includes a...

Students learn to develop the equation of a line from its graph. They also learn to write the equation of a line from the slope and the y-intercept, a point and the slope, and two points. They also investigate slopes of lines that are...

Students learn to associate the slope of a straight line with a constant rate of change. They also learn to calculate the rate of change from data points on a line, using the correct units. Students also learn to read from a linear...

In this activity, students write rules for real world functions. They make a table to compare function values and graph linear functions on the coordinate plane.

Students learn how to create a table of values for a simple linear function and use the table to create a graph on squared paper. They use the graphing calculator to display the ordered pairs and find values of corresponding to values of...

This activity has students find patterns in the areas and perimeters of a given series of figures. Students' then use graphing calculators to graph the values and to find linear and quadratic functions to describe the patterns.

Students input a function in either y= of f(x)= form, and then the site from WyzAnt does the rest! A detailed graph is shown in less than a second. Students can change the window used to view the graph as well as whether to have...

In this activity, students find patterns to solve problems, explore functions, and graph linear functions on the coordinate plane.

Several examples are presented to demonstrate the process of graphing functions, including linear, quadratic, and rational functions.

Using the graphing method, several systems of nonlinear equations are solved. Follow each example step by step to see how solutions are derived.

Students use the CBR 2 to gather distance and time data for various walking speeds. They observe the effect of change in direction and speed of motion on distance versus time graphs. Students interpret and analyze graphs, calculate slope...

Students determine how the temperature of water affects the dissolving time of a sugar cube. They create, interpret and analyze graphs of data, find an equation of the line of best fit, and relate slope to rate of change.

In this activity, students walk in front of a calculator-based ranger CBR and try to match a distance-time graph. They examine the rate of change, and analyze and interpret the graph of a function.

Here is a site that clearly and thoroughly explains the equation of a line, including how to find points on a line, intercepts, and how to recognize the equation of a line. There are example problems solved, problems for the student to...

Students compare the heating rates of wet sand and dry sand and study the effect of evaporation on heating rates. They create, interpret and analyze graphs of data. They also relate slope to rate of change.

Students perform an experiment that simulates a leaking pipe and gather data on volume of water lost over time. They graph the data collected as a scatter plot, find the equation of the line of best fit, find the total volume of water...

In this activity, students can use the motion detector to measure their current height and obtain a mean value. They will use this and earlier data to plot a graph of height versus age. Students will identify the mathematical model that...
