High schoolers use yearly averages over a five-year period to understand weather trends for a specific area.

Fifth graders practice using estimation. In this estimation lesson, 5th graders add, subtract, multiple, and divide using whole numbers, fractions, and decimals. Students decide upon instances when estimation is more appropriate than...

Learners explore the concept of absolute value inequalities and equations. In this absolute value inequalities and equations lesson, students discuss how to solve absolute value inequalities and equations through teacher led discussion...

Pupils build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using logs.

Students create their own "weather" map using data from x-ray sources. They analyze and discuss why it is important to organize data in a fashion in which is easy to read. They compare and contrast different x-ray sources using a stellar...

Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...

Young scholars differentiate between the terms 'tornado watch' and 'tornado warning' and simulate the conditions that produce tornadoes. They read "Night of the Twisters" by Ivy Ruckman and conduct an experiment using two-liter plastic...

Learners read an explanation from a NASA Web-based textbook, then demonstrate an understanding of the text by using it, along with FoilSim, to complete an activity that manipulates the lift coefficient equation.

Students classify clouds as transparent, translucent or opaque. They conduct an experiment to determine the visual opacity of several classroom objects and then conduct further observations of clouds.

Dr. Math discusses the usefulness of standard form of linear equations on this page. The Dr. discusses parallel and perpendicular lines as well as graphing techniques. The Dr. touches on what the canonical form is and its usefulness.

Detailed math tutorial features notes and examples that discuss graphing lines and introduces the concept of slope, the standard form of the line, the point-slope form, slope-intercept form, and parallel and perpendicular lines.

[Free Registration/Login may be required to access all resource tools.] Students learn to graph the equation of a line in standard form. Students examine guided notes, review guided practice, watch instructional videos and attempt...

Join Joan the chameleon in an exploration of lines and slope. You'll be drawing lines, calculating slope, using equations and more!

[Free Registration/Login may be required to access all resource tools.] Students learn to use a table to graph functions recognizing linear equations and the equations of horizontal lines and vertical lines. Students examine guided...

Explanation of linear equations and four types of slopes: positive, negative, zero, and undefined. Practice problems for the students are provided and a reinforcement activity using a graphing calculator is offered for the teacher's use.

This tutorial covers x & y intercepts, point-slope form, slope-intercept form, graphing, and more. Use the practice problems at the end to check your skills.

Students groups act as aerospace engineering teams competing to create linear equations to guide space shuttles safely through obstacles generated by a modeling game in level-based rounds. Each round provides a different configuration of...

The basic concepts of graphing are covered on this site, including points, slopes, equations of lines, and y-intercept. A quick discussion on the Pythagorean Theorem is also concluded. Several practice and application problems are...
