Create larger-than-life insects for the classroom. Bugs are usually pretty small, but during the Jurassic period they were huge. Kids use diagramming and scale conversion to enlarge a modern day insect so that it is as big as its ancient...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

What happens to a volume when you scale the dimensions of a rectangular prism? In this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of...

In this math worksheet, learners find the centre of enlargement, scale factor and label the images. The images give a perspective of how the size scale changes.

Students use Geometer's Sketchpad to examine the scale factor when in is applied to the length of a figure's sides. They look at how the scale factor affects the side lengths, perimeter, and area of the figure that result. They work with...

Students apply concepts of scales to solve problems. In this geometry lesson, students solve real world problems using scales, proportions and ratios. They predict the actual size of a model given the scale drawings.

Students change the scale of a work of art using ratios, percentages, and proportions. While this is technically an art lesson, there is quite a bit of mathematics involved in converting to the correct scale.

Students study art by Matthew Ritchie. Students view pictures of the artist and discuss art that is created specifically for a designated area. Students create pen and ink drawings on letter size paper. Using an overhead, students...

Pupils multiply the vertical and horizontal distances from the center of dilation by the scale factor. The independent practice prompts the class to analyze the relationship between the image and pre-image. The lesson is...

Engage scholars in a ratio lesson that employs real-world scenarios. Learners will compare the length and width of pictures and use a table to identify ratio patterns. They watch "Math Can Take You Places" and discuss jobs that use math...

Save trees! Save graphite! Save ink! Go paperless! Make a list, mindmap, sketch an idea. Import, scale, rotate, and add text to images. Save content into books and share your creations. All this and more is yours with a free visual...

Scholars make a giant scale model of an object. They will take a regular item and enlarge it to five times its length and width. They attempt this same concepts with a 3D model.

Double, toil ,and double linear dimensions. Learners first complete an assessment investigating how doubling linear dimensions affects the area of pizzas and the volume of popcorn containers. They then complete an activity investigating...

Students engage in a lesson that is concerned with the concept of similarity. This takes higher order thinking skills and being able to separate into categories. Specifically in this lesson they are introduced to the scale and how it is...

Seventh graders watch a video and enlarge and shrink scale by applying proportional thinking. They practice measuring, using percentages, computing area, and problem solving.

Put an insect together piece by piece with a fun and artistic puzzle project. To increase small group collaboration, learners use photos of insects cut into one-inch squares to create an enlarged puzzle version of the image. Extension...

Middle and high schoolers solve fifteen problems from six exercise sets covering transformations, reflections, rotations, and enlargements. The solutions are provided.

Learners select a person whom they admired and get a picture of that person. Then they go through a lesson on creating and using grids. They learned how to properly use a grid to increase the scale when they create a drawing.

Eighth graders understand that proportional enlargement of shapes doesn't change the angles of those shapes. In this similarity lesson, 8th graders complete exercises to create enlargements of shapes and understand similar shapes.

In this solar surface instructional activity, students use a photograph taken by the Swedish Vacuum Telescope to answer 6 questions about the solar features in the photograph. Students determine the scale of the image, they determine the...

Learners create cubist drawings using grids and enlargement.

In this star circles worksheet, students solve six problems given a diagram of a time-exposure photograph of the stars. Students determine the scale of the image, the location of the North Celestial Pole, they identify Polaris and they...

Students measure a sculpture of a human and measure other students. They determine the average size of humans and create a life size image of the sculpture. They work with percentages as they create the images.

Whales are all big, but some are larger than others! Kids will love sorting the 10 whale species by size at their desk (whale cut-outs provided). Next, use a whale rope to visualize how long each of these whales actually is. A large...
