Students address a major misconception in astronomy, the understanding of scale. The lesson is designed to introduce students to both celestial coordinates and to the first rung on the distance determination ladder, parallax.

Students analyze the details of a topographic map and create one of their own by utilyzing a map of elevations.

Third and fourth graders are introduced to the concept of map scale. Using an illustration, they discuss if it shows the actual size of the object and why scale is used to represent areas. They use some items in the illustration to...

Learners build different shapes using sketches. In this geometry lesson, students explore measurements and units as they build and create models of buildings. They use SketchUp to create and manipulate shapes.

Learners solve for the different ratio and proportion of a problem. In this geometry lesson, students show their knowledge of how to solve proportional relationships. They convert between percent, decimals and fractions.

Seventh graders study ratios, scale and distances according to a three dimensional model.  For this exploratory lesson students create their own constellation and prepare an oral presentation that describes their model. 

Seventh graders construct a three dimensional model of a constellation. For this constellation lesson, 7th graders make a blueprint for a scale model of the constellation and create their models. They present their models to the class.

Eighth graders practice the skill of reading maps.  In this geography lesson, 8th graders participate in a classroom lecture on how to read a map. 

In this scale drawing worksheet, students determine the actual distance when given a scale drawing. They draw objects to scale. This one-page worksheet contains 8 multi-step problems.

In this pentatonic scale worksheet, students review the meaning of scale, notes, and flats. They read about the notes used in the Chinese pentatonic scale and learn how to name them. There are no questions associated with this worksheet.

In this scale problem worksheet, 6th graders solve 9 different problems that include reading a map scale of a neighborhood. First, they determine the distance between each person's home as illustrated. Then, students determine the...

Learners calculate a house's perimeter by using photographs by determining the appropriate scale. They decide on the number of strings of Christmas lights that would be needed to decorate the house.

Sixth graders are introduced to the concept of scale. As a class, they create a model of the solar system taking into account the scale between the planets and the Sun. To end the lesson, they examine "Dina the Monster Bee" and discover...

Students research and explore the earth's past and make comparisons with the earth's present. They map out a timeline that explains how the earth and its organisms have changed over time. Studnets create a scale for their time line, they...

Young scholars are challenged to create optical illusions using using cut-outs. The activity provokes thoughtful discussion about scale.

Students read and discuss the story The Corn Dolly by Terry Jones. The teacher shows the class a corn dolly and they need to design and construct furniture that is appropriately scaled for that specific dolly.

Students examine the history of equal temperament, the modern standard of tuning a piano. Proportion calculations of octaves and perfect fifths are utilized to calculate the frequency of each note in a major scale.

Through this lesson, students will learn how to use ratios to create a scale drawing of their classroom's floor plan. It provides adaptations, discussion questions, assessment rubric, and suggested readings to help develop students'...

In this Cyberchase video segment, Bianca volunteers to take over an important job at a copy shop. She must make a life-size copy of a photo of the King of Sloovoonia.
