Enlargements
Make enlargements with and without centers. Pupils work through seven problems dealing with dilations or enlargements. The first couple items are strict enlargements without centers, while the others have centers. Class members also...
Curated OER
Similarity
In this similarity worksheet, students 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 determine the...

Running Around a Track I
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...
Curated OER
Similarity
In this similarity worksheet, 9th graders solve and complete 6 different types of problems. First, they complete the statement in the box shown. Then, students determine whether they agree or disagree with the statement and given...
Curated OER
Proportions 1
In this proportion worksheet, students find the missing side of 4 shapes that are similar to their mate. Shapes include triangles and quadrilaterals,. In the second part of the worksheet, students use the scale factor to find missing...

The Math in the Design and Building of Bridges
Research various types of bridge designs. Your class will be asked to consider what it would be like without bridges while learning about how they work. They will construct a model bridge based on given parameters. They then calculate...
Curated OER
Volume of a Cylinder
Pupils predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive lesson.

Circles: A Geometric Perspective
Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...
Curated OER
The Mandelbrot Set
Students are introduced to the notion of a complex number and function iteration in order to motivate the discussion of Julia sets and the Mandelbrot set.
Curated OER
The Mandelbrot Set
Students explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.
