Students analyze symmetries of quadrilateral tilings and discover how various types of symmetries, used alone or in combination, can generate the same pattern in more than one way.

Ninth graders design a safe passage through a 2-D obstacle. For this geometric math lesson, 9th graders engage in a hands on activity to better understand the concept of geometric and algebraic perpendicularity. Students will work in...

Seventh graders are introduced to making inferences about artifacts. Using a grid system, they locate the artifacts and determine where they originated from. They use this information to make conclusions about the way people lived...

Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.

Young scholars experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Students investigate the law of reflection by using mirrors. In this physics lesson plan, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

In this polynominoes worksheet, 10th graders solve 9 different problems relating to various types of polynominoes, such as triominoes and tetrominoes. First, they determine how many different types of triominoes they can locate and draw...

Students research the Cartesian Coordinate System and its many uses in the world of mathematics and algebra.

In this secondary mathematics activity, students determine each word played during a Scrabble game.  They are given a mat clue for each word played and determine the correct placement on the board and the score at the end of the...

Students explore geometry by participating in a pattern identification activity. In this tetrominoes lesson, students define the characteristics of congruent and symmetrical shapes. Students practice translating shapes across quadrants...

Sixth graders view a video of tessellating an egg shape. They focus upon the problem solving strategies used and how tessellation geometry was used to construct the three dimensional figure. They create their own tiling patterns.

In this polynominoes worksheet, students solve 9 different types of polynominoes problems. First, they identify that a polynominoe is a polygon made from squares of the same size and connected to each square. Then, students determine how...

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...

Learners produce original tessellations, using equilateral triangles where three unique symmetrical faces rotate, use shape, pattern/repetition, and color to create a striking composition, and create "beasties" inspired by bestiaries of...

In this algebra worksheet, 4th graders play a game of scrabble using equations. They use the rules for scrabble when solving the equations.

In this phonics activity, students practice matching consonant blends, with a partner, in a game of I Spy Blends where they match a set of consonant blend cards to a variety of pictures.

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...

Seventh graders create 3 original tessellation using polygons. They slide, turn, rotate and glide their designs on the computer. They print their tessellation on a T-shirt and teach the 6th graders about tessellations.

Geometers investigate patterns and symmetry, and examine the artwork of M.C. Escher on the Internet. They compare his style to the floor and ceiling tiles in the classroom. If you have ImageBlender™ software, you could have your...

Seventh graders produce a tessellation of an original design developed using an equilateral triangle, where three unique symmetrical faces rotate throughout their creation.

In this tessellations and transformations worksheet, 10th graders solve 9 different problems that include various types of tessellations. First, they write examples from history of tessellations and name 3 artists. Then, students define...
