Tenth graders investigate dilations and explore the dilation transformation before investigating the properties of a dilation using Cabri Jr. Young scholars extend the concept of dilatation to the coordinate plane.

Take mathematics to the hoop! Pairs first measure the linear distances on a basketball court. Using those measurements, they determine the scale lengths to create a scaled model. To finish the activity, learners create models of the...

The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

In this rotational symmetry activity, students solve 14 short answer and graphing problems. Students identify the order and magnitude of given figures.  Students find the scale factor of a dilation given a graph.

Pupils take photos from a given distance and determine the height of the person using a scale factor. Pupils calculate the ratio of student actual height to student photo height. They take pictures from 3 different distances to see if...

Upper elementary and middle schoolers examine the Volumes of Similar Figures. They investigate the relationship between corresponding sides and evaluate the volume of similar figures. Pupils record their findings on various activity...

In this similar polygons learning exercise, students identify the corresponding sides of polygons.  They use proportions to solve problems.  Students determine the scale factor of similar figures.  This two-page learning...

Pupils will analyze scales as related to models and real life in this geometry lesson. They work together to compare the dimensions on a model as compared to the real building.

In this simplifying ratios worksheet, 10th graders solve and complete 24 various types of problems. First, they complete each ratio and reduce when necessary. Then, students find the length and width of each rectangle described. They...

Learners calculate the surface area and volume of shapes. In this geometry lesson, students create different scales and calculate the volume and area for each shape. They compare and contrast between the different scales and shapes.

Eighth graders solve problems using proportions with scaled drawings. They work with maps and blue-prints discussing scales and plans and examine different polygons and figure out the scale factors or proportions they have been changed by.
