Sixth graders examine how to select samples and apply them to an experiment. In this sampling lesson, 6th graders use a bag of yellow and blue cubes to take a sample. They predict how many of each color there are the bag. They set up and...

Designers measure their own rooms and produce a scale drawing. They use the Internet to visit sites to find the costs of purchasing new carpet, paint, or anything else they would like to add to their room. Using a $1500 budget, they will...

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

Students participate in a lesson that investigates Newton's Second Law of Motion. They conduct an experiment of observing balls that are rolled down a ramp. The lesson includes background information for the teacher for preparation and...

Steel is an example of homogeneous mixture, also called an alloy, which is made of iron and carbon. The presentation introduces learners to elements, compounds, and mixtures. They explore their similarities and differences, and then take...

Exponential growth is modeled by learners as they analyze and interpret the data presented in this real-life scenario centered on the destructive invasion of the Giant African Land Snail. Learners get a touch of history and practice...

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

Eighth graders identify that a ratio is a comparison of two numbers and that a proportion is an equation that equates two ratios. They identify the extremes and means of proportions, as well as the product of the extremes equals the...

Young scholars demonstrate and describe the effect of multiplying or dividing by a fraction less than or greater than one. They create and explain a variety of equivalent ratios that represent a given situation. Students draw a picture...

Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.

Students test their knowledge of the Wright Brothers and their aircraft, and compute ratio of two numbers to determine the ratio between wing span and length of aircraft.

Students gain appreciation for the drawings by Leonardo da Vinci. They show human emotion by drawing facial features in correct proportion - studying ratio of eye width to the rest of the facial features. They create values by varying...

Students use hypsometers to measure tall objects.

Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

Students measure, analyze, and compare the ancient Egyptian canon of proportions using a mummy, painted images, and photographs of people today.

In this similar figures learning exercise, students solve and complete 4 different problems. First, they write a proportion and substitute. Then, students find the cross products and simplify. Finally, they divide each side to find the...

Sixth graders practice the conversion of percents and fractions. They focus on the fact of both fractions and percents are part of a whole. In the independent practice the students also work with solving proportions.

In this earth and beyond worksheet, students answer short answer questions about the atmosphere, the chemical compounds in Earth's atmosphere. Students visit different websites to conduct research of the discoveries of the scientist who...

Students create projects on Astronomy using math concepts and use of Internet resources.

Students work in groups that are engaged in different activities at different times. They watch the video "Madagascar" and collect data pertaining to the Fish Eagle's arm spam. They work together to perform mathematical computations...

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

High schoolers differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.

Sixth graders use newspapers to investigate fractions. They work in small groups to categorize articles, measure them with the grid transparency, and calculate the values represented. Afterward, they write a reflective essay on the role...

In this Algebra I/Algebra II worksheet, students solve problems involving direct variation.  The two page worksheet contains a combination of twelve multiple choice and free response questions.  Answers are included.
