New ReviewTurn to the resource to discover rotational symmetry. Viewers of an informative video first learn the definition of rotational symmetry. They then see how to identify the order of rotational symmetry for a figure.

New ReviewTransform 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...

Our planetary neighbor has some explaining to do! Scientists are mystified by the fact that Venus spins in the reverse direction of all other planets. A thoughtful video lesson explains different hypotheses as well as the science leading...

Don't cry over broken pottery. A cross-curricular lesson challenges pupils to consider how to restore ancient pottery. Using a computer program and their knowledge of transformations, they come up with a way to recreate the original design.

Do other planets experience night, day, and the seasons like humans do here on Earth? Examine planetary motion using real images of the planets through a simulation from PBS's Space lesson series. After observing the motion of each...

No need to change anything about the resource. The first of eight modules in the MVP Geometry unit focuses on transformations in the coordinate plane. It connects translations, rotations, and reflections to congruence, symmetry, and...

Didn't catch the last solar eclipse? Now every day can be eclipse day, thanks to an interactive lesson from PBS' Space series for middle schoolers! The well-rounded multi-media experience includes video clips, an interactive, and...

Let's talk torque! Science scholars evaluate experimental setups during an interactive from the Rotation and Balance series. Individuals calculate the torque of differently arranged weights to determine the effect they have on a balanced...

Do your young physicists get a little unbalanced when it comes to talking about torque? Scholars examine the effects of weight and distance on a balanced system with a simple interactive from the Rotation and Balance series. The resource...

Approach the activity from the right angle. A discussion-based activity leads helps learners understand angles in terms of rotation. Individuals use manipulatives to explore the properties of angles and learn how to name them. The...

Double the transformations, double the fun! Using the knowledge of transformations, the video combines two transformations of figures on the coordinate plane. The segment of a geometry playlist, finds a single transformation that will...

Build a pattern by rotating a figure around one of its vertices. A segment of an extensive playlist on basic geometry introduces the concept of tessellations through regular tessellations. The video shows how to create tessellations and...

Change places by pivoting the figure. The section of a geometry playlist introduces rotations by making the connection to rotational symmetry. The presentation provides formulas to use with the coordinates when rotating a figure around...

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...

Combine transformations and triangle congruence in a single lesson. Scholars learn to view congruent triangles as a rigid transformation. Using triangle congruence criteria, learners identify congruent triangles and the rigid...

Coordinate transformations on a graphing calculator. Pairs use a graphing calculator to determine a method to transform figures, either by translating, reflecting, and rotating. Using the method, they develop a generic formula for...

Introducing ... the Transmographer. Young mathematicians investigate translations, reflections, and rotations. The applet lets users perform transformations on triangles, squares, and parallelograms.

Helicopters fly with the help of gyroscopic precession. An uplifting Vertasium video explains two common forces, momentum and torque. Demonstrations of both forces—along with scientific explanations—help develop an overall understanding...

How many moves does it take to land an out-of-this-world aircraft? Given a spaceship and a landing pad, pupils work together to determine the sequence of transformations needed to land it. Individuals show they can perform...

Flip, turn, and slide to get there. With the aid of hands-on materials, pairs transform a figure from one place on the coordinate plane to another. They determine a sequence that will move one figure to another and present different...

Generally, heavy things go on the bottom and light things go on the top. Here is a video that presents a spinning wooden disk that doesn't appear to follow the rules. Young scientists hypothesize why this is before watching a video in...

Can energy be created? The textbook says no, but then how do you explain what is going on here? The Veritasium video demonstrates an experiment related to energy. Scholars watch the set up, come up with a hypothesis, watch the test, then...

Please, place your shoes on the shoe rack. Pupils create a personal design for a pair of Air Jordans. Working in pairs, learners record their predictions on how to move their shoes to the shoe rack and record each step along the way as...
