Eighth graders extend skills for representing and solving linear equations to linear inequalities. Lesson activities build understanding and skill by plotting ordered pairs of numbers that either satisfy or do not satisfy a given...

If the Greenland ice sheet melted, sea levels would rise by about 20 ft; if the Antarctic ice sheet melted, sea levels would rise by 200 ft. Scholars explore ice melting through the analysis of different ice samples, clean and dirty ice....

Learners step up to the plate as they first complete an assessment task using linear equations to determine the best company from which to buy baseball jerseys. They then evaluate provided sample responses identifying strengths and...

Are we there yet?  Young trip planners learn about their state and plan a trip. They will select sites to see in three cities in their state, and record associated costs in a spreadsheet. While this was originally designed as a...

Fifth graders develop strategies for estimating ages, and illustrate results by graphing and interpreting scatter plots to compare x and y coordinates.

Fifth graders estimate the size a population (ecosystems) Students make a chart from information collected then create a graph (line or bar) from this information. Students do a lesson where they observed, examine, and record data...

Fifth graders collect, organize, interpret data. In addition, they compare different textures, color including graphical representations such as bar graph, line graph .Students also describe the uses of rocks and how to use that to...

Students, through a case study of actual water sources in Washington State, identify major sources of aquatic pollution. They also categorize pollutants, make inferences about the effects of pollutants on the environment and construct...

Students travel one at a time in a straight-line path and attempt to maintain a constant velocity. While one student walks, jogs, or runs, the other group members time the "runner" while standing at five-meter intervals along the path....

Students solve problems identifying the functions and inverses. In this algebra lesson, students identify a one-to-one function, and perform the horizontal line test. They analyze data and graph their results on a graph.

Students listen to Jack and the Beanstalk and determine what they think are the most common words.  In this Jack and the Beanstalk lesson, students reread the story, count the words they chosen and graph those words. Students graph...

Students use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at which...

Eighth graders investigate slopes using real life scenario. In this algebra lesson, 8th graders model and interpret real life data. They plot their data in a coordinate plane and discuss the results with the class.

Fifth graders examine the many uses of coordinate grids. In this graphing lesson, 5th graders write data driven equations, discuss the x and y-axis, and determine if using 2 or 3 ordered pairs is better.  Students complete several...

Young scholars identify the slope of linear functions. In this slope lesson, students collect data and graph it. They write equations with no more than two variables and use technology to explain their data.

Students graph and solve quadratic equations. In this functions lesson, students analyze a quadratic equation using three points on a curve to define the graph of a quadratic function. They find the vertex and intercepts of the graph.

Students convert degrees between two different units. In this algebra lesson, students graph linear equations and identify the line of best fit. They use their line of best fit to make predictions given a set of data.

Students use a graphing calculator to examine the association between the data points and equation of a linear relationship. They write equations in standard form and then graph the equations using the slop-intercept form. Answer Key...

Eleventh graders test the pH and alkalinity of Pago River. In this ecology lesson, 11th graders collect data and use spreadsheet to graph results. They analyze and share their findings with the class.

Students use a graphing calculator to examine the association between the data points and equation of a linear relationship. They write equations in slope- intercept form. Answer key included.

Students analyze the weather patterns in Namibia. They create a graph of the yearly temperatures and use the internet to gather information. They discuss how the weather goes in cycles in the area.

Fifth graders explore the concepts of range, median, mode, and mean through the use of graphs drawn from models. They use manipulatives to represent data they have collected within their groups, and compare the differences between mode,...

Students explore slope.  For this middle school mathematics lesson, students analyze and interpret graphs as they investigate slope as a rate of change.  Students use a motion detector to collect data as they walk at different...

Students find the slopes of linear functions. In this graphing lesson, students analyze linear equations and calculate the slope of the line. They graph a line given the slope and y-intercept.
