#### Rotations, Reflections, and Symmetry

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

EngageNY

#### Reflections

Facilitate creativity in your math class as individuals learn the definition of a geometric reflection and correctly construct a model, as well as its reflected image. They use a perpendicular bisector and circles to elaborate on...

EngageNY

#### Rotations

Searching for a detailed lesson to assist in describing rotations while keeping the class attentive? Individuals manipulate rotations in this application-based lesson depending on each parameter. They construct models depending on the...

EngageNY

#### Transformations—The Next Level

Transform your geometry instruction by incorporating role play into math class. Pupils begin by completing an assessment to locate unknown angles, and then performing a simulation activity to better understand rotations, reflections, and...

Lesson Planet

#### Transformations

How is it transforming? Using videos on metamorphosis, hook the class with this STEM plan on transformations. The open inquiry lesson instructs the class to explore the effects of transformation on the coordinate plane. Groups develop...

Lesson Planet

#### Transformations in the Coordinate Plane

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Lesson Planet

#### Module 6: Congruence, Construction, and Proof

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This unit...

Lesson Planet

#### Right Triangles Inscribed in Circles II

So many times the characteristics of triangles are presented as a vocabulary-type of lesson, but in this activity they are key to unraveling a proof. A unique attack on proving that an inscribed angle that subtends a diameter must be a...

Lesson Planet

#### Investigating Functions

Late in algebra 2 or early in pre-calculus, learners are developing a kind of functional intuition. This worksheet goes a long way toward training this skill by helping to expose patterns of transformations through both general and...

EngageNY

#### Complex Numbers and Transformations

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Lesson Planet

#### Pixar: The Math Behind the Movies

When will we ever use this? A Pixar movie maker explains to learners how math is used in the creation of animated films. The movie maker discusses the importance of coordinate planes, transformations and translations, and trigonometry.

Lesson Planet

#### Reflections and Equilateral Triangles II

Given the lines of symmetry in an equilateral triangle, your learners find where the pre-image vertices are mapped onto the new image. They explore the properties of equilateral triangles, the impact of reflections, and the idea that the...

Lesson Planet

#### Reflections and Equilateral Triangles

Your learners collaboratively find the lines of symmetry in an equilateral triangle using rigid transformations and symmetry. Through congruence proofs they show that they understand congruence in terms of rigid motions as they prove...

Lesson Planet

#### Experiment with Transformations

Rotate it, reflect it, and slide it! This lesson plan gives your geometers an opportunity to explore transformations in the coordinate plane. Working in small groups, learners travel to four stations with a figure you have assigned them...

Lesson Planet

#### Unit Squares and Triangles

This is an interesting geometry problem. Given the figure, find the area of a triangle that is created by the intersecting lines. The solution requires one to use what he/she knows about coordinate geometry, as well as triangle and angle...

Lesson Planet

#### Similarity and Dilations - Discover Properties of Similar Figures

Learners investigate properties of similar figures. In this properties of similar figures lesson, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships between...

Lesson Planet

#### Geometry: Translations and Reflections

Group work and participation is used to perform a specified translation or reflection. In this geometrical translation instructional activity, small groups of pupils are each given a shape to plot on a coordinate grid. Each shape is then...

Lesson Planet

#### Dilations with Matrices

Examine dilation with matrices with your class. Learners write a conjecture for how the scale factor determines the size of an image. They then use their conjecture to write a matrix multiplication problem for the illustrated triangle...

Lesson Planet

#### Transformations in the Coordinate Plane

Young mathematicians explore the concept of transformations by constructing a polygon on their calculator using lists. They transform the polygon using lists and reflect, rotate, translate, and dilate polygons.

Lesson Planet

#### Transformations and Functions

See the evolution of transformations . . . into functions. Young mathematicians consider three different transformations of points in the plane. Then they identify whether each transformation is a function.

#### Authentic Activities for Connecting Mathematics to the Real World

Check out the handout from a presentation that contains a collection of high school algebra projects connecting a variety of mathematics to the real world. Activities range from simple probabilities to calculus. The activities can be...

Lesson Planet

#### Reflections

Learners explore reflection of polygons on a coordinate plane. They examine the relationships that exist between corresponding points and sides.

Lesson Planet

#### Exploring Transformations with Matrices

A page right out of the Holt Geometry book. Use a graphing calculator and graph paper to explore transformations with matrices.

Lesson Planet

#### Scale Factor Area Perimeter

Mathematicians compare triangles at different scales. In this geometry instructional activity, students calculate the area and perimeter of triangles. They use the Ti to make observation of the change that takes place as the triangles...
