Rotations
Use this math worksheet to have your learners practice constructing a reflection of a shape drawn on a grid by using rotation. This simple worksheet has six problems for the pupils to solve, and includes and answer sheet.
Curated OER
Transformation
In this transformation learning exercise, students identify and solve 10 different problems that include various images. First, they determine whether each object illustrated is a mirror image or reflection of the other image in the...
Curated OER
Translating Transformations in Geometry
Students create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.
Curated OER
Using Coordinate Geometry by Land, Sea and Outer Space.
Young scholars complete a table of values and plot points, as well as construct a graph on a coordinate grid. They construct two graphs on the same coordinate system, and identify the point of intersection. Students represent and record...
California Mathematics Project
Reflections
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.
Virginia Department of Education
Transformations
The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation. They perform...
Mathed Up!
Mixed Transformations
Viewers learn how to identify and perform a variety of transformations with a video that provides seven items on transformations. Pupils demonstrate their understanding of dilations, reflections, rotations, and translations. The video...
