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.

In this rates and unit price worksheet, students problem solve and calculate the answers to ten word problems and mathematical equations dealing with ratios, proportion and missing values.

Students measure the volume of a clear container using a candle and sand. In this measuring volume lesson plan, students time how long a candle stays lit in a clear glass container. They fill it with sand and find the volume and then use...

In this composition of soil learning exercise, high schoolers study the make-up of soil by identifying the amount of air in the soil, the amount of water in the soil, the size of the mineral grains in the soil and the proportion of humus...

Students measure distances using indirect measurements. In this geometry lesson plan, students apply proportion and ratios to measure heights of different objects. They differentiate between direct and indirect measurements.

Students explain that, in order to create realistic faces, artists study live models, use mathematics to explain correct proportion, and practice by making sketches. They create a self-portrait using these principles.

Students distinguish between weight and mass. They examine how in oscillations of a mass against an elastic spring--in the absence of gravity, or in horizontal motion--the length of the oscillation period is proportional to the square...

Students investigate the use of proportion using gesture drawing as the subject matter. They create a painting using the elements of art and principles of design.

Students identify the different types of water and explain in what proportions they exist on Earth. They identify and correctly label the parts of the water cycle and how these parts interact with each other. Students identify the...

Learners examine why and how elections are conducted in Australia. They compare first-past-the-post, preferential and proportional systems of voting. Students brainstorm the names of elected representatives in the current federal...

Students create a mini city using proportions that fit a model human they construct using tin foil. They plan the city including a library, sports arena, living spaces, parks and businesses. When constructing the paper buildings, they...

Eighth graders, after brainstorming all the places they see percentages in every day life (sales, basketball, grades, etc.), calculate percentages from bases and parts in word problems. They review their notes together on percentage...

Students explore Greek Mythology. In this Greek Mythology unit, students read myths, pantomime vocabulary words, practice research skills, create city-states, and demonstrate knowledge of ratios and proportions. This unit includes many...

Learners measure and apply their knowledge of proportion to solve problems. In this geometry lesson, students measure using a meter stick, small mirror and measuring tape. They compare and contrast their measurements to objects outside...

Young scholars solve problems using ratio and proportion. For this math comparison lesson, students identify methods used to solve and compare ratio and proportion in the real world. They apply criss cross multiplying to solve their...

Young mathematicians identify central angles, arcs and radius of circles in this pre-calculus lesson. They identify the proportion of the circle based on its radius while they convert between degrees and radians measurements.

Students apply their math skills to develop an accurate estimate of the height of a tall tree. Three different methods are outlined. All grade levels should be able to perform the shadow method and the proportional method.

Sixth graders plan a trip for a family of four choosing their travel plan by studying maps to decide upon a route and visiting Websites to get airline and travel schedules. They use ratios and proportions as well as converting fractions...

Introduce your math class to the perimeter of a circle. Teach them that pi describes the relationship between the circumference and the diameter. As a hands-on investigation, pairs or small groups use string to compare these two values...

In this similar polygons worksheet, 10th graders solve and complete 20 various types of problems. First, they solve each proportion. Then, students write a ratio expressing the slope of a line through each pair of points. In addition,...

In this algebra worksheet, students solve equations by applying direct variation relationship. They solve problems using proportions and ratios while using direct variation. There are 3 problems with an answer key.

In this algebra learning exercise, students divide circles into equal portions as they explore percents and decimals. They convert between decimals and fractions using ratio and proportion. There are 8 questions.

Students relate the concepts of linear functions to the game of monopoly. In this algebra lesson, students solve problems with ratio and proportion. They collect data and graph it.
