Students engage in a lesson that is concerned with the cumulative concepts introduced in a Calculus course. They review exponential growth and how it is used to measure increase in values. Students also apply the use of the differential...

Students build a model of their school playground. They view models from the classroom (such as a globe, doll house, or cars). Students share observations about the models. They use a paper mat to represent the playground and use...

In this rate of change instructional activity, students compute the amount of time a block of ice will take to melt. There is only one question on the page.

Students view the film Fog of War and discuss the most striking elements of the film. They focus on chosen lessons from robert McNamara's life such as: empathy, rationality and proportionality.

Students discuss methods of building forms with clay (ball and variations, snake, flat sheets). They draw a stick figure of what their sculpture may look like, including correct figure proportion.

Fifth graders create clay artwork that resembles African and Egyptian monolithic sculptures.  In this visual arts instructional activity, 5th graders are shown examples of monolithic and figural sculpture from Egyptian and African...

In this math activity, students solve the expressions with using the values of the variables to find the solutions. They also solve the set of proportions.

Young scholars investigate the human impact on coastal land. In this coastal surveys lesson plan, students choose a coastal area and complete a survey sheet about the area. They choose a topic about a sea side village called Dunwich to...

In this ratio measures worksheet, 10th graders solve and complete 8 different types of problems. First, they find the largest angle of a hexagon. Then, students solve the proportions shown. They also name the similar figures by filling...

Students challenge their math knowledge through a series of lessons designed to engage critical thinking and reasoning skills. In these problem solving lessons, students work with the Pythagorean Theorem, time zones in different regions...

Young scholars discover where Canadian immigrants have come from and their contribution to the country. In this cultural lesson, students use a map to indicate the native homes of immigrants, and create a paper chain to represent the...

In this similar figure worksheet, students use similar figures and indirect measurement to determine distance.  They use proportions of similar figures to determine scale figures.  This two-page worksheet contains 8...

Seventh graders use a protractor to measure angles and solve a problem involving distance. In this measuring angles with a protractor lesson plan, 7th graders calculate the distance of a line on a diagram by using a protractor to measure...

Young scholars use similar triangles and a sight tool to find the height and distance between large objects. In this similar triangles lesson plan, students use a constructed sight tool to measure the distance and height of an object...

Eighth graders understand that proportional enlargement of shapes doesn't change the angles of those shapes. In this similarity lesson, 8th graders complete exercises to create enlargements of shapes and understand similar shapes.

Students view a quicktime video of basketball players going from Atlanta to Springfield, Mass. In this scaling lesson, students use a map to calculate the distance of the trip and the length of travel time. Students apply ratio and...

Students sculpt a bust out of clay using naturalistic features.  For this sculpture lesson, students use themselves or classmates as models to ensure correct form and proportion of a hollow bust.  This lesson includes pictures...

Students apply concepts of scales to solve problems. In this geometry lesson, students solve real world problems using scales, proportions and ratios. They predict the actual size of a model given the scale drawings.

In this geometry worksheet, 10th graders use a straightedge and a compass to construct congruent segments and angles, bisect a segment and an angle, construct perpendicular and parallel lines, construct tangents, circumscribe a circle...

Twelfth graders create an artistic version of a Vetruvian teen. For this anatomy lesson, 12th graders design an experiment to test the theory of the ideally proportioned man. They present their findings in class.

Learners play a game of hopscotch as they simulate birds migrating north through wetlands. They compare the game to real bird migration and discuss how the health of the wetlands is proportional to the health of birds.

Given a set of six paint mix ratios, artistic mathematicians produce an equation that relates the number of parts for blue paint to parts for yellow paint resulting new shades of green. 

Toss 100 pennies (or poker chips or any other two-different-sided objects) and remove all of those displaying tails. Line them up and repeat. The lines of pennies collected get smaller each time, successfully representing half-life.

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class...
