Students experience how to illustrate some of the many connections between number and geometry. Through this 2-3 day focus on square numbers and triangular numbers, students make connections among mathematical topics.

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Students identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have been...

Students explore the origin of tangram. In this algebra lesson, students form different shapes and figures using tangram. They solve for the area of different shapes without using any geometric formulas, but the idea of tangram being put...

Students explore the concept of copying one another. In this early childhood lesson plan, students discuss what a copycat is and why people copy one another. Students then discuss the story Rainbow Fish: The Copycat Fish, recording...

Students listen to the book Mouse Shapes and identify the shapes in the book as it is being read. In this shapes instructional activity, students identify the shapes in the book, and then play with cut out shapes that they can hold in...

For this algebra worksheet, students calculate how many snaps is done over a certain amount of time. They chart and graph their data. There is an answer key.

Students study West Virginia quilts. In this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Learners create books about shapes.  In this shape lesson, students select a topic such as points, lines, angles, planes, polygons, quadrilaterals, triangles, circles, and polyhedra.  In groups, they create an illustrated...

Tenth graders create polynomial quilts. In this polynomials lesson, 10th graders use concrete models, such as construction paper, to create various shapes described. Students use the FOIL method to multiply terms and to get a square...

Students use a graphing calculator to examine the association between the data points and equation of a linear relationship. They write equations in slope- intercept form. Answer key included.

In this secondary mathematics learning exercise, students investigate exponential growth as they predict the height of a stack of paper formed by tearing one sheet of paper in half over and over again for thirty tears.  The one page...

Students write equations based on a pattern. In this algebra lesson, students calculate the arithmetic and geometric mean of a sequence. They rewrite word problems as a linear equation and solve real life scenario based on the given data.

Second graders manipulate triangles to discover the concepts of slides, flips and turns of a geometric shape.

Students identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of cookie dough and...

Fifth graders identify lines of symmetry., similar and congruent shapes. They use construction paper to create their own symmetrical shapes. Students create stained glass frames containing symmetrical, congruent and similar shapes.

Students explore symmetry.  In this geometry and scientific inquiry instructional activity, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Students measure the plane's...

Fifth graders examine the geometry of quilts. They discuss the history of quilting, design two nine-patch squares, exchange one design on an Internet bulletin board, and construct a hot pad that is quilted.

High schoolers create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.

Students practice representing problems found in the real world in terms that can be translated into mathematical expressions. The situations are represented in tables and graphs by students.

Students study triangles. In this triangle lesson plan, students compare and classify triangles while milling to music. Students will also trade triangles so they can match up with other similar triangles. Triangles are provided.

Learners create a glossary of geometric terms while exploring tangram manipulatives.

Students are exposed to different types of sequences. in this sequencing lesson, students learn about simple sequences, multiplication sequences, declining sequences, the Fibonacci sequence and other sequences.

In this math and logic worksheet, students solve 2 problems in which they examine a picture of 5 squares in a particular formation. Students build this with toothpicks. Students are instructed to move a specified number of toothpicks to...
