In this algebra instructional activity, students convert between units. They write expressions and simplify them. There are 4 problems with an answer key.

Pupils explore percent increases and decreases. They calculate the percent increase and decrease. Students use math to solve problems and communicate. They apply the given formula for percent increase/decrease.

Students examine the patterns that exist in Pascal's Triangle. They explore multiples and factors. Sudents use an applet to create and color the multiples in Pascal's Triangle.

Students discover patterns and sequences. They use a website to explore patterns and fractals. Students share their discovery of fractals and their patterns with the class. They develop a list of patterns used in everyday life.

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...

Students measure using tools they have made. In this algebra lesson, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.

Students create visuals of the effect of a spring scale. In this algebra lesson, students use the navigator to graph the effects created by a spring scale. They draw conclusion from the graph.

In this Algebra II worksheet, 11th graders solve problems involving direct variation.  The two page worksheet contains explanation, examples, and twenty-one problems.  Answers are not included. 

Young scholars observe and solve examples of corresponding angle postulates, alternate interior angle theorems, and exterior and consecutive angles. They complete the Determining Angle Measure With Parallel Lines worksheet.

Middle schoolers investigate water usage, water available, and water demand historically in the local area. They use projections of water usage, availability and demand up to the year 2050. Students use graphs to relate as well as...

Students explore and examine the increases and/or decreases for water user groups: irrigation, municipal, manufacturing, steam electric power generation cooling, livestock, and mining. They utilize percentage changes during their...

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 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 trial...

Students spend one month keeping track of the mileage and gasoline amounts they or their family has used. Information is entered into a spreadsheet to help calculate the average gas prices over time.

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Learners explore the differences between surface water and ground water. They collect data using maps and graphs and investigate a Texas river basin and a nearby aquifer. They complete a written report of their findings regarding the...

Students use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Students solve problems dealing with percents using "is over of" algorithm.

Pupils work in pairs to investigate what it takes to prove that two triangles are similar. They work through various shortcuts to find which are enough to show a similarity relationship between the triangles. Small groups work with the...

Student are assigned one of the sections on whole numbers. After reviewing the content, they teach their assigned sections to other class mates. They publish their findings on a PowerPoint slide show to use when they teach their section.

Students perform mathematical operations on complex numbers. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice performing operations on complex numbers.

Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson plan very effectively demonstrates the concept of...

Provides examples and a video lesson that explains ratios and proportions and shows how to solve them.

Explore word problems about ratios and watch and listen to all the steps needed to solve.
