Eighth graders are presented with a tile pattern showing an apparent square surrounded by four octagons. They are asked to answer a question about congruency and angle measurements, as well as prove that the interior shape is really a...

This is an algebra tiles lesson in factoring polynomials. The link found a the bottom of the page links to an index of over two hundred lesson plans in various mathematical topics.

Use tiles to represent variables and constants to solve algebra problems. Solve equations, substitute in variable expressions, and expand and factor.

How can you describe this shape's perimeter and area? Students review expectations and work together to solve problems about area and perimeter.

Were off to get the measure, the wonderful measure of side! The students will identify the longest side of an object and measure its length with a variety of non standard units.

This task applies reflections to a regular hexagon to construct a pattern of six hexagons enclosing a seventh. The focus of the task is on using the properties of reflections to deduce this seven-hexagon pattern. Aligns with G-CO.B.6.

Students will determine whether a set of objects contains an even or odd number of members using strategies such as pairing objects or attempting to divide the objects into two equal subgroups. Discussion questions and explanations are...

This cross-curricular middle school unit integrates mathematics and visual art. Through the study of the M.C. Escher?s work, learners explore tiling from both a mathematical and artistic point of view. Points for discussion and...

[Free Registration/Login Required] In this lesson, students will connect the concepts of counting each square unit and multiplying the side lengths to compute the area of a rectangle. They will extend this knowledge by computing a side...

Explains five methods for multiplying binomials: (Distributive Method, FOIL Method, Vertical Method, Grid Method, and Using Algebra Tiles).

This fifth-grade lesson explores the area of a rectangle with fractional side lengths. We tile the rectangle with unit rectangles and show that the area is the same as would be found by multiplying the side lengths. We multiply...

A wealth of material to supplement classroom instruction on factoring of polynomials. Lessons offer methods and guidelines for factoring as well as examples; practice exercises allow students to begin testing their factoring skills; and...

Test your memory while you learn about eclipses of the Sun. Click on tiles to reveal pictures of solar eclipses and maps of the path of the November 2012 eclipse in Australia. Try to find matching pairs of pictures.

Looks at tessellation artists, including M.C. Escher, Robert Fathauer, and Roger Penrose. This is followed by a discussion of fractals and their similarities and differences to tessellations, and links to lessons and resources on...

Lesson plans for many student activities which introduce the concept of polyhedra into the classroom. Some activities can be accomplished by hand with paper, pencils, and scissors, but the unit works best if the students can regularly...

Choose a difficulty level. Then click on the tiles (squares) to reveal pictures of molecules. Try to match two pictures.

This lesson plan deals with tessellations and their geometric concepts. Upper elementary and middle school students will also explore polygons, symmetry, analyze patterns and explore the role of mathematics in nature and culture.
