Geometry
In this congruent figures learning exercise, students analyze a geometric shape and choose from the answer box any figures that are congruent to that shape. There are 3 problems.
Curated OER
1st Geometry
In this geometry worksheet, learners choose the multiple choice answer to 15 questions involving several different elements of geometry.

Basic Right Triangles
Elementary schoolers examine the attributes of triangles. In this triangle lesson plan, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw...
EngageNY
Why Move Things Around?
Explore rigid motion transformations using transparency paper. Learners examine a series of figures and describe the transformations used to create the series. They then use transparency paper to verify their conclusions.

Dry My Laundry!
Meant to be a pre-field trip lesson, this can also serve as a cute and simple activity to use when your little ones are learning about evaporation or surface area. The children cut tiny t-shirts out of paper towel material, wet them, and...
Curated OER
Congruency Basics
Fourth graders investigate congruent shapes. In this congruency instructional activity, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.

Problem-Solving Strategy: Act It Out Word Problems
In this congruent shapes worksheet, students determine if they can us the five figures to form a figure congruent to the rectangle. Students follow the steps to solve the problem: understand, plan, solve, and look back.
Curated OER
Tangram Perimeters
Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.
Curated OER
Finding Volume
Sixth graders develop a rule for finding the volume of rectangular solids using colored cubes. They investigate the properties of solid figures and find the volume of an object by counting units. Students fill spaces with standard-sized...
Curated OER
Ship Shape
Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...
Curated OER
Lines of Symmetry
Fourth graders demonstrate lines of symmetry using polygons, pentominoes, and block letters of the alphabet. They describe, identify, and analyze characteristics and properties of geometric shapes.
Houghton Mifflin Harcourt
Unit 5 Math Vocabulary Cards (Grade 6)
Acute angle, line of symmetry, and vertex are a few terms you'll find in a set of 90 flashcards designed to reinforce math vocabulary. Included in the set are two types of cards; a word card printed in bold font, and a definition card...

Constructing Reflections
An informative video and handout provide the basic information needed to reflect any pre-image across either of the axes on the coordinate plane. The printed resource provides a preview of reflecting across lines other than an axis....
Curated OER
Slides, Flips. Turns......It's All On A Memory Book Page
Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.
Virginia Department of Education
Rotation
Rotate this resource into your lesson plans. Scholars rotate polygons in the coordinate plane by multiples of 90 degrees. They then compare the original and new figures to develop conjectures about coordinate points after rotations.
Curated OER
Can You Build It?
Students investigate the concept of perimeter. They design there own figure and measure the perimeter of it. The lesson is given the context of the shape being a path that is traveled by a ladybug. This provides the shape of the plane...
Curated OER
Exploring Perimeter
Students explore perimeter. In this geometry and measurement lesson, students create squares and rectangles using given perimeters. Students construct four sided shapes with given perimeters using the computer program "Math Keys:...

One Revolution for Robot
Students calculate the revolution and circumference of circles. For this calculus lesson, students derive the formulas for their given shape. They use the d=rt to calculate the distance and rate of travel.
Curated OER
Math Challenges
Students engage their critical thinking skills to solve challenging math problems. In these problem solving lessons, student work with tessellations, weights/measurement, reasoning, surface area, geometric shapes, and algebraic procedures.
