After completing a task involving examining the ratio of areas of triangles and circles in a given figure, scholars examine sample responses to identify other strategies they could use to solve the problem.

Did you know that leaky faucets waste $10 million worth of water? Conservationists perform an experiment and draw best-fit lines to explore how the US Geological Society determined this value.

Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers in scientific notation. 

So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using...

All triangles have some things in common. Using these properties of triangles, learners find missing angle measures. Scholars use the Angle Sum Property and properties of special triangles throughout the lesson.

Work with your class to connect series and parallel circuits to hybrid cars. The lesson introduces basic circuit diagrams before having scholars apply the understanding of the difference between parallel and series circuits to...

Kids usually love crayon resist projects. It is so fascinating for them to see how the dark paint accentuates and resists the waxy crayon. Here are instructions for executing a crayon resist project of your own. Tip: Make the project fit...

Primary readers complete the activities in a Pebbles, Sand and Silt FOSS kit. As a class, they are given a group of rocks and they are to categorize them based on their activities in the FOSS kit. They use this information and apply it...

A fun art project, this lesson plan incorporates math and listening skills as young artists play with a new painting technique. First the teacher models how to draw a cat using shapes, an oval for the body, triangles for the ears and so...

Is there such a thing as useful microbes? Get ready to perform experiments on applying microbes for wastewater treatment. The first installment of the three-part unit provides background information to prepare young engineers for two...

First graders explore counting and classification. They sort leaves, create graphs, write sentences for the data in the graphs, develop graphs for shapes, favorite animals, birthdays, and participate in a die prediction game.

Students investigate the concept of solving problems when given it in words and employing a wide variety of methods. They practice applying a logical sequence to find the solution to a problem while estimating possible answers to help in...

Students experiment to determine if a game is fair, collect data, interpret data, display data, and state and apply the rule for probability. Students use a simple game for this experiment.

Students share in the family histories of their peers as told through the quilt stories, and apply math skills by using invented strategies to determine the (approximate) age of the quilt from the information given about the date it was...

Students investigate the concepts relating to the solving of parametric equations. They take the derivatives of parametric equations during guided and independent practice using the problems provided in the lesson plan. Students also...

Students participate in a formal assessment of knowledge concerning the basic Integration Formulas. They apply the review practices given in the resource links to problems found in the assessment. The teacher should use these as review...

Ninth graders gain an application level understanding of probability, symmetry, and ratios and rates that exists in one's everyday environment relative to human genetics.

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

For this geometry worksheet, students are given the side lengths of polygons and asked to calculate the perimeter, area and shaded region. There are 30 questions with an answer key.

Students find examples of the Golden Ratio on the human body through measurement. Additionally, students learn about the use of the Golden Ratio and the Golden Rectangle in art and architecture. A very interesting lesson for the students!

Students examine composition of dirty bomb and its possible effects on a city, and investigate simulations of such an event; students use computational and problem solving skills to assess damage and prepare report proposing solution to...

Students work with "ice" in order to gain a practical application of math concepts that evolve into an inquiry-based study. They determine if the dimensions of the ice make a difference in the way the ice floats in the water.

High schoolers participate in activties examining ratios and proportions. They use graphs to interpret data showing the government's budget for prisons. They present what they have learned to the class.

Students calculate ppm and ppb by using unit analysis when given a ratio of amounts. They determine in ppm what constitutes a health risk for a particular toxin given data and whether local health officials should close a lake...
