Tenth graders identidy and define various geometry terms, Students create exact replicas of a shape that is either smaller or larger than the original shape. Students prove that their entire shapes are larger or smaller in the same...

Ninth graders explore the concept of ratios. In this ratio lesson, 9th graders construct a to scale time line that starts at the beginning of time. Students determine the correct placement of big events in time such as when the dinosaurs...

Students create scale models of Earth, the Moon, and the distances within the universe. Working in groups, they construct their models of Earth and the Moon on a scale of 50:1 and calculate how far apart to place their models. They...

Students explore two dimensional geometric figures. They explore the relationships and measurements of geometric figures. Students apply proportion and scaling. They design a city park for students and teenagers.

Students solve problems using ratios and proportion. In this algebra lesson plan, students analyze skittles and their different colors as they apply the properties of ratios and proportions to solve their problems.

Students sort and compare/contrast the lengths of various whales. They sort pictures of whales in order of smallest to largest, and given a rope marked with the lengths of the whales, they compare the actual lengths of the whales.

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Swimming is more fun with quantities. The short assessment task encompasses finding the volume of a trapezoidal prism using an understanding of quantities. Individuals make a connection to the rate of which the pool is filled with a...

Students compare the lengths of whales using different lengths of rope. They illustrate one whale in life-size proportion.

Second graders receive an "Expedition Ticket" to travel through the Polar Regions- the Arctic and the Antarctic. They research polar bears and make drawings that are to scale.

For this comparing ratios worksheet, students solve and complete 3 different problems using the screens shown. First, they write a ratio that compares the shaded part to unshaded part illustrated. Then, students use the same grid to...

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Third graders practice measuring different objects. They discover the concepts of ratio and proportion and practice converting numbers into the correct unit. They read stories as well to help them with the concepts.

Students experiment with scale to solve a problem presented in a video clip. They determine the correct size to use when constructing a model and evaluate the use of proportions in real life applications.

Students are given a budget and an alternative-fuel vehicle. Using a map of Texas, they are given a starting point and determine how to arrive at their destination within 72 hours. They use the internet to research the alternative fuel...

Young scholars convert their physical models of a playground from a previous lesson into a map of the playground that includes a scale and key. They examine and discuss examples of maps, view an image to map photo essay, and create a map...

Fifth graders carefully analyze the artwork, Les Emigrants, and explore the reasons that people emigrated to the United States, and what life was like for new arrivals. They discuss what things immigrants were able to bring with them and...

Students explore finding the surface area and volume of cubes and cylinders. They construct similar three-dimensional figures from a two-dimensional drawing. Students derive the formula for volume and surface area through examination...
