Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Are you searching for a purpose for geometric constructions? Use an engaging approach to explore dilations. Scholars create dilations using a construction method of their choice. As they build their constructed dilation, they...

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

Young scholars examine the process of drawing a picture to scale. They analyze and discuss real-life blueprints for a house, and create a scale drawing of an original invention using calculators and rulers.

Blend art, adolescent snacking habits, and math to create new cereal boxes. Secondary learners review scale drawings. They use this information to construct cereal boxes to scale and will compare their creation to the original product to...

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

Guided by their analysis of a scene, their initial sketches, and renderings, set designers begin to craft a scaled, 3-D model of the set of the play they have chosen. 

Young mathematicians practice measuring acurately with a protractor. They convert measurements using a scale factor, then translate the new information into diagrams. This instructional activity should be a hit in that it's mostly...

Pupils practice drawing geometric figures. In this geometry lesson plan, learners complete an activity that requires them to draw angles and shapes to the nearest degree.

How many ways can you create a dilation? Many! Individuals strengthen their understanding of dilations by using various methods to create them. The new technique builds on pupils' understanding of the ratio method. Using the ratio,...

Reflect on altering scale factors. The last lesson in the series of 22 has the class compare the two scale drawings they created. They realize that the scale drawing becomes a scale drawing of each other. Class members continue to work...

Students create 3-D models of Lake Benthos. In this scale drawing lesson, students create a 3-D model of Lake Benthos. Students work in groups to create the models. Students use the models to to encourage people to conserve natural...

Learners explore scale factor as they create a scale drawing of a box, then determine the surface area and volume of the original and the scale drawing. The one page worksheet contains activities and procedures with four questions....

How can you fit an entire school on one sheet of paper? You use scale! Scholars measure rooms in the school and, using the correct scale, design a floor plan that includes area calculations with their data.

Young scholars demonstrate the process of creating a scaled rubber band enlargement of a simple drawing. They observe and discuss a teacher-led demonstration, and create a scaled rubber band enlargement of simple drawings and their...

Students comprehend what makes up the physical community. Read and construct scale drawings and models. Explore the history of infrastructures and how the contributions of science, math and industry have led to the development of their...

Pupils determine scale factors from one figure to another and the scale factor in the reverse direction. Scholars compute the percent changes between three figures. 

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson...

Your young architects use the Internet to research tall structures or sky scrapers to help in the design of their scale drawings. This is lesson one of three in which learners design, build, and test model skyscrapers for seismic safety....

Students investigate the concept of a model and how it is used to represent something that is real. They recognize how the model can be applied to other types of concepts like the solar system. Students create a scale drawing of a house...

Students measure the actual size and distance of the solar system using scale and ratio. They watch and discuss a video, create a distance-scale solar system model, and compare the scale sizes of planets to their actual sizes.

Ocean explorers or mathematicians research the wreck of the CSS H.L. Hunley. They investigate the actual dimensions of the Hunley using math and measuring skills. Afterward, they sketch a large scale drawing of the submarine outdoors on...

Young scientists gain a better understanding of space, the solar system and its vastness by creating a scale model. Students first need to calculate the distance between each of the nine planets according to the size of their scale. This...
