Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Develop a strategy for finding the area and perimeter of irregular figures. Building on an understanding of finding area and perimeter of rectangles and triangles, learners apply the same concepts to composite figures. After...

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. 

When told to describe a line, do your pupils list its color, length, and which side is high or low? Use a worksheet that engages scholars to properly label line graphs. It then requests two applied reasoning answers.

Learners perform translation and reflection. They identify the coordinate points of the new graph and create a formula for the movement. They identify the pre-image the and after image.

Students explore the world of art and culture, including the works of M.C. Escher. They identify and create original tessellations. Students use a wealth of interactive multimedia applications. They explore the artistic representations...

Second graders identify horizontal, vertical, and oblique lines on a worksheet after learning them in class. They demonstrate a horizontal line with their arms while saying the word and use their arms with no talking to demonstrate...

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Students transform polygons.  For this tessellating lesson, students design a picture containing a translation and a rotation.  They create a template of a translation or a rotation.  Students tessellate and decorate a...

In this circles worksheet, learners fill in 6 fill in the blank statements about circles and solve calculate the answers to 13 questions involving different measurements of circles.

Tenth graders study graphing exponential functions. In this transformations instructional activity, 10th graders apply inquiry to determine how changes to a parent function affect its graph. Students analyze transformed graphs and...

A comprehensive guide for learning all about plane shapes with definitions, properties, types, solved examples, and practice questions.

First graders begin to learn about plane shapes in Kindergarten. This lesson will serve as review of plane shapes' characteristics and extend into practice in categorizing shapes by defining attributes.

In this series of STEAM activities, students will discover the concepts of geometry through shape exploration and the creation of choreographic sequences. Another activity in this module will allow students to identify shapes by applying...

These activities will allow students to discover the concepts of geometry through shape exploration and the creation of choreographic sequences.

In this lesson, students use movement and the creation of human structures to help them understand angles, plane shapes, and geometric solids.

Looks at the lines of symmetry in different types of polygons. Includes ten practice questions. Each question is accompanied by an explanation of the answer.
