Young scholars explore the concept of Venn Diagrams through word problems. In this Venn Diagram lesson plan, students solve word problems about groups of people using Venn Diagrams. Young scholars use survey results about MySpace and...

Because of the work of John Dalton, we are able to write formulas for compounds. The hands-on experiment has scholars prepare a compound from its elements. Using mass data, individuals write the empirical formula for the compound.

Teaching linear function relationships using contextual information is beneficial to pupils' understanding. The lesson uses problem solving to build linear functions given different information for each problem. This is the second...

Pupils determine the theoretical probability of winning a game of marbles. Individuals compare the theoretical probability to experimental probability for the same game. They continue on to compare two different probability games.

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Students create scale drawings, and ultimately scale models, of real-world objects in this Math lesson about ratios, proportion, scaling factors, and cross products. The lesson includes ideas for cross-curricular extensions and is...

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

Middle schoolers examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

Students investigate the concept of using proportions to compare quantities while also practicing calculations for foreign exchange rates. They develop the skill of solving for unknown quantities of money while using an algebraic equation.

Students measure a set of Russian dolls using the metric system. In this measurement lesson plan, students identify certain relationships between sets of measurements by measuring a set of Russian dolls and presenting their findings to...

Fourth graders study fractions. In this fractions lesson, 4th graders define fraction-related vocabulary words. Students use beads to study fractions. Students draw shapes to study fraction equivalency and brainstorm fractions they use...

In this similar figures worksheet, students identify corresponding sides and corresponding angles of given polygons.  They identify similar figures.  This three-page worksheet contains 18 problems.

Students 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.

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 explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...

Students explore aspects of the Vietnam War and how it relates to the heritage of America. In an attempt to understand the level of involvement, students analyze statistics from the Vietnam war. Students watch a video, read a book, and...

Students discuss the nature of fractions and compare fractions based on a similar whole to determine relative size.

Sixth graders practice using negative numbers by completing number equations.  For this math problem solving lesson, 6th graders discuss the different ways negative numbers can be used in a math problem and practice completing...

Students sort a bag of M&M's by colors and solve a variety of comparison problems. They determine which pile of M&M's has the most, the least, and answer questions comparing two piles. Students also order the piles of M&M's...

Students investigate the properties of lines and congruent triangle theorems as well as apply geometric properties and relationships to real-world mathematical problems. Given two different scenarios, they examine maps that have been...

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...

Students map data on employment in wood products manufacturing in Oregon counties. In this Oregon forest lesson, students discover the percentage of people employed in the forest manufacturing industry. Students create a box and whisker...

For this Geometry instructional (work)sheet, learners are instructed on how to find the geometric mean.  Students are then shown how the geometric mean is applied to proving similar triangles.

Students design a United States flag using reasoning. They describe their design to make it easy for it to be duplicated. They share their designs with the class.
