Taking a Spin

For Teachers 9th - 12th Standards
It does not divide into 360 evenly, so it cannot work. The resource extends pupils' thinking about rotational symmetry. By asking for a figure with a rotational symmetry of a seemingly impossible angle, the activity requires learners to...

Transmographer

For Students 8th - 12th Standards
Introducing ... the Transmographer. Young mathematicians investigate translations, reflections, and rotations. The applet lets users perform transformations on triangles, squares, and parallelograms.
Lesson Planet

Transformations of Trapezoids

For Students 9th - 12th Standards
Transform trapezoids to a T. Pupils identify reflections and rotations that take trapezoids and map them back to themselves. They consider both isosceles and non-isosceles trapezoids.
Lesson Planet

Transformations of Rectangles and Squares

For Students 9th - 12th Standards
Young mathematicians create a list of transformations that carry a rectangle and a square onto themselves. They take into account both reflections and rotations.
Lesson Planet

Transformations of Parallelograms and Rhombi

For Students 9th - 12th Standards
Back to the original figure. Young mathematicians consider transformations that carry figures onto themselves. The figures in question are a parallelogram and a rhombus.
Lesson Planet

Transformations of Regular Polygons

For Students 9th - 12th Standards
Let polygons be polygons. Learners identify reflections and rotations that carry regular pentagons and regular hexagons onto themselves. They then make generalizations about n-gons.

Transformations and Symmetry

For Teachers 9th - 10th Standards
Flip, turn, and slide about the coordinate plane. Pupils define the rigid motions and experiment with them before determining the relationships of the slopes of parallel and perpendicular lines. The sixth unit in a nine-part series...

Between the Lines

For Students K - 12th Standards
Explore linear and square dimensions by comparing areas of similar figures. A creative set of five activities designed for elementary through high school classes asks young scholars to compare areas of specific polygons. The first two...

Visualizing Rotations

For Students 8th - 10th Standards
Have classes been going in circles as they study rotations! Math scholars begin with an exploration of rotations using patty paper. As they progress through the lesson, they examine compositions of reflections and their resulting image....

Reflections

For Students 8th - 10th Standards
Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third lesson in a seven-part series.

An Introduction to Transformations

For Students 8th - 10th Standards
Use geometry to transform learning! This introduction to transformations has pupils use patty paper and rubber bands to create rotations, reflections, translations, and dilations. Individuals learn the vocabulary and notation related to...

Rectangles Inscribed in Circles

For Teachers 9th - 10th Standards
Putting a rectangular object into a circular one—didn't the astronauts on Apollo 13 have to do something like this? Learners first construct the center of a circle using perpendiculars. They then discover how to inscribe a rectangle in a...

Translations

For Students 9th - 10th Standards
Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.
