Students measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale factor...

Conduct research on the Internet about labyrinths and mazes to learn about proportions and ratios. Inquisitive minds design their own maze, one maze is chosen and proportionately enlarged to 20 feet by 30 feet. This is a fun challenge...

Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.

Learners discover fascinating facts about the Great Pyramid of ancient Egypt and construct a scale model of the pyramid with this fun activity worksheet. 

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Middle schoolers measure the dimensions of different sizes of paper. Using a copy machine, they discover dilations. After enlarging and shrinking particular copies, students examine rates, ratios and percentages and discover the...

Pupils explore the concept of scale. In this scale lesson, students are given directions scaled in inches and pupils must convert them to feet. Students take a section of a map and create a bigger scaled model of the section.

In this project worksheet, students use rubber bands to enlarge pictures of butterflies found at the Butterflies of Illinois website.

Students work collaboratively to create artistic renderings of digital photographs using a color value scale and grid techniques in this late-elementary school lesson based upon Ted Rose's book Discovering Drawing. The lesson includes a...

Seventh graders explore how proportion controls the image of a drawing. They examine a coordinate plane and discuss plotting. Student experiment drawing an object one size, and then drawing an identical object on a different scale.

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...

In this similarity worksheet, learners identify similar shapes.  They determine the scale factor of the similar shapes and find their volume and area.  Students enlarge shapes according to the given scale factor.  They...

The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...

The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Viewers learn how to identify and perform a variety of transformations with a video that provides seven items on transformations. Pupils demonstrate their understanding of dilations, reflections, rotations, and translations. The video...

Whoops! Travis accidentally put too much butter into the recipe. Your bakers must find out how to alter the recipe to accommodate different changes by using unit rates and ratios . The activity has multiple parts and calculations with...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

In this transformations worksheet, learners solve 25 short answer problems.  Students dilate, reflect, and translate points and figures in the coordinate plane.  Learners determine scale factors and lines of symmetry of figures.

Here is a activity that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

In this nebula worksheet, students read about the Crab Nebula and calculate the average speed of the expanding gas. They determine the size of the smallest clumps of gas and they draw the diameter of the solar system to scale.

Young scholars collaborate to create a painting in the style of Keith Haring. In this subway art lesson plan, learners study the distinct style of artist Keith Haring and design a large scale canvas on styrofoam. They study the details...

Open up your pupils' eyes and minds on dilations. Scholars perform dilations on a trapezoid on the coordinate plane. They compare the image to the preimage and develop generalizations about dilations.

Rings and golden nuggets contain the element gold, but how small can you break it down before it is no longer considered gold? A helpful presentation explains the basics about atoms, elements, and isotopes through a presentation.

This lesson plan combines a creative building activity with analyzing a butterfly photograph and using problem solving to complete the puzzle. It blends art and science very well. Students will learn and enjoy the process. The extension...
