Similar Shapes
In geometry, similar and congruent shapes are often confused. Shapes that are similar are the same shape, but a different size. This activity gives young learners some practice in identifying similar shapes. There are five polygons...

Congruent Polygons: Copying Stretchy Shapes
Third graders investigate congruent polygons through dance. In this congruency lesson, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Match Shapes in Compositions
Third graders draw shapes that are congruent with each other and identify other congruent shapes. In this congruency lesson plan, 3rd graders also apply specific colors from the color wheel in their shapes.

Congruence in Triangles
In this geometry activity, students identify and label triangles as being congruent or not. They use the SSS, ASA or SAS as their description. There are 18 questions with an answer key.
Curated OER
Equilateral Triangles
Students examine the attribute of equilateral triangles. In this equilateral triangle lesson, students examine a number of paper triangles to determine how they are classified. They determine how triangles are depicted in Navajo rugs.

TRIANGULATEERS IN THE REAL WORLD
Students explore about triangles and the simple machines that are made from those triangles. They are able to identify the kinds of triangles in the machines, tell how the triangular shapes make the machines function, and build a simple...
Curated OER
Snowflake Curve
Students develop an appreciation for complex structures in nature. They observe patterns in nature in relationship to the Real World. Students use observation skills to assist in problem solving. They show comprehension of the concepts...
Curated OER
Testing For Congruent Triangles
Students define and discuss congruency and the corresponding parts between congruent triangles. They create a pair of congruent triangles, test for congruency, and complete a worksheet.

Medieval Mathematicians and Whimsical Windows
Third graders demonstrate their mathematical knowledge of symmetry and reflection using congruent geometric shapes while working as an artist and mathematician looking at a medieval-styled stained glass window.
Curated OER
Congruent Boxes
Students decorate the congruent faces and edges of boxes in exactly the same way. They teach the terms "congruent," "faces," and "edges" to their parents.
