Curated OER
Reflections of Symmetry
Students use video and the Internet to identify examples of bilateral and radial symmetry in the world around them. They create symmetrical reflection designs using pattern blocks and paper.

Slides, Flips, and Turns
In this transformation learning exercise, 5th graders determine if a pair of figures are related by a slide, flip, or turn. The learning exercise reviews rotation, reflection, and translation.
Curated OER
Reflections Of
Students create angles using mirrors. In this angle reflection lesson plan, students draw angles, then use mirrors to create angles using reflections and measure the new angles.

Preparation -- The Right Way to Help and FOrm for Poetic Reflection
Students prepare for their service learning project by listening to a representative from the Lake Michigan Federation. They volunteer their time to clean up the coast line. They reflect on the event by writing a poem about their...
Curated OER
Reflection, Translation and Rotation
In this reflection, translation and rotation worksheet, students determine which of these things have been done to s set of figures. A reference web site is given for additional activities.
Curated OER
Reflection, Rotation or Translation?
In this reflection, rotation and translation worksheet, students determine which has been done to a set of 6 figures. A reference web site is given for additional activities.

Sound Wave Reflection
Learners explore sound waves. In this sound wave lesson, students determine the path traveled by sound waves in an acoustic room. Learners consider how sound travels and reflects, then they calculate the rate sound travels at.

Exploring the Definition of Reflection
Students practice using a protractor and ruler to draw various points and lines. Using a computer, they draw the points and lines in the program and describe the differences between their drawing and the computer's drawing. They complete...

Translation and Reflection
Bring about the change you want to see in the world or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to develop...

Reflection on Educational Goal Setting and Self-Assessment
Third graders evaluate their performance at school. They examine their most recent spelling test scores to determine whether or not they met their goals for the test.

Brain Train
A lengthy presentation on geometric reflections is here for your young geometers. Learners consider a shape, then must choose between four reflections to find the one that is a true vertical, horizontal, or diagonal reflection of the...

Soda Can Mirrors
Here is an entertaining and illuminating lesson on morphed images. Middle schoolers make cylindrical mirrors by wrapping soda cans in reflective mylar. First, they try to determine what the images are that are embedded in the plan by...
Curated OER
Transformation
In this recognizing reflection, translation, and rotation of figures instructional activity, students observe figures on grid paper, and read and follow directions to reflect, translate, and rotate them. Students solve 3 problems.
Curated OER
Congruent Segments
The task, should your class decide to take it, is to list a series of reflections that transfer a line segment from one position to another.
Curated OER
Congruent Rectangles
Very simply, geometers examine a pair of rectangles on graph paper and find a translation and rotation to demonstrate their congruence. A couple of questions follow to stimulate critical thinking about other possibilities.
Curated OER
Coordinate Plane Transformations
Geometric transformations are explored by high schoolers. They will create a set of instructions for plotting coordinates representing an original transformation of a real-world figure. These instructions are shared with middle...

How Big is Big?
In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of students' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise, they...
