#### EngageNY Geometry Module 3: Extending to Three Dimensions

Building on the understanding of congruence studied in Module 1 and on similarity studied in Module 2, the 14 lessons in the Module 3 collection focus on developing a bridge from geometric measurement in two dimensions to understanding...

Lesson Planet

#### How Much Proof Do We Need?

Are two angles enough? Given two triangles, the class determines through the definition of similarity and transformations whether the two triangles are similar. Provided with pairs of triangles and measurements, small groups find out...

Lesson Planet

#### Discovering Dilations

Scale up the dilation factor. Using a dynamic geometry software program, classmates discover the relationship between a pre-image and its image after performing a dilation. Individuals create their own dilations and fellow class members...

Lesson Planet

#### Geometry Definitions

Geometry is full of shapes, figures, and corresponding things here and there. The guide shares all of the key pieces of geometric information in a nicely color-coded and labeled sheet.

Lesson Planet

#### Similar Triangles

Although a rather complicated topic, this video manages to clearly explain the concept of solving problems involving similar triangles. It employs problem solving to determine whether two figures are similar triangles. In addition, it...

Lesson Planet

#### Similar Triangles (Part 2)

Building on concepts in the first part of the series on similar triangles, installment number two explores how to find the values for given angles in a triangle. These problems are solved by using algebra and ratios. A step-by-step...

Lesson Planet

#### Verifying Dilation

Working in pairs, geometry students will construct a dilation and consider the properties associated with the similar figures that are created to verify the properties of dilation. This activity can be done using dot or graph paper and...

Lesson Planet

#### Identifying Similar Triangles

Math whizzes work with angle sums and exterior angles to figure out the measure of other angles. This particular publication provides comprehensive support in the form of an anticipatory activity, questions designed to prompt discussion,...

Lesson Planet

#### Choosing the Best Cylinders

Don't be fooled: the taller glass doesn't always hold the most. Given the dimensions of different cylindrical containers for beverages and popcorn, pupils calculate the volumes. They see how changing the dimensions affects the volume and...

#### CK-12 Middle School Math Concepts - Grade 6

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

Lesson Planet

#### Green Acres is the Place to Be!

Nurture a love of math and farming at the same time. Pupils apply geometry concepts, such as surface area and volume of three-dimensional shapes and similarity ratios, to farming contexts. They consider the dimensions of bales of hay,...

Lesson Planet

#### How Tall is the Tree?

Pairs or small groups work together to determine the height of a tree using similar triangles. Learners make a judgement which direction to let a tree fall to avoid hitting any structures. They then write letters to the principal...

Lesson Planet

#### 2 and 3 Dimensional Shapes

Take a similar approach to three dimensions. Pupils develop the relationship between areas of similar objects and see how they relate to the ratio of the sides. Building upon area formulas, small groups put together volume formulas for...

Lesson Planet

#### Next Top Model

Create a world of similar models. The geometry and measurement unit uses real-world scenarios to create models of familiar buildings and rooms. Scholars work with blueprints and scale models to compare areas and volumes between the...

Lesson Planet

#### Catch Me If You Can!

Crime doesn't pay, but everyone can learn from it. Learners consider different situations involving mischief at a school, such as stink bombs and rockets, and analyze them using mathematics. They must apply trigonometry, quadratic...

Lesson Planet

#### Grades 7-8 Solving Equations

Create a similar blueprint. The differentiated lesson has pupils work in teams to create a brochure, scale model, or blueprint of a selected house with some minor changes. Once finished, team members present their final projects to the...

Lesson Planet

#### Proportional Representation

Sometimes the solution is all a matter of perspective. The short assessment task presents a problem to pupils that requires them to make sense of a diagram. Once learners see two similar triangles, the rest of the solution is solving a...

Lesson Planet

#### Similar Shapes

Similar shapes are all about the scale. Given seven problems, pupils use scale factors to determine measurements within similar shapes. While solving the problem, scholars also determine whether two figures are similar and use area and...

Lesson Planet

#### Smarter Balanced Sample Items: 8th Grade Math – Target G

Transform the thinking of transformations with six sample items that illustrate the first four standards in the eighth grade geometry domain. Items use the coordinate plane to transform figures and analyze the relationship of the figures...

Lesson Planet

#### Human Tree: Dilations

Look at dilations exponentially. Using a fractal from a museum exhibit, the installment from the Math at the Core: Ratios series introduces the term dilation. The presenter points out that dilations can make images either smaller or...

Lesson Planet

#### Similar Shape Volumes

More power to you if you can calculate volumes. Viewers of an informative YouTube video learn about the volumes of similar three-dimensional figures. They see how figures with sides that have a scale factor of n have volumes with a scale...

Lesson Planet

#### Similar Shapes Areas

Just how similar are the areas of similar figures? An educational YouTube video describes how to determine the areas of similar figures. Given the area of one figure and the measurements of corresponding sides of each figure, viewers see...

Lesson Planet

#### Similar Shapes Sides

Scale up a lesson on similarity. Young mathematicians watch a video that investigates the sides of similar figures. They see how to calculate missing sides from the given measures using scale factors.

Lesson Planet

#### Congruent and Similar Shapes

By definition, a congruent shape remains similar, but similar shapes may or may not be congruent. Scholars watch a video explaining the sometimes-confusing concept. Practice problems ensure pupils demonstrate their understanding to...
