Students explore proportional relationships in this activity as they build a ratio table in order to project how many tiles would be needed to cover the area of a floor.

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...

In this March, 2003, article, the investigation board that was investigating the Space Shuttle Columbia disaster found more evident that hot gases was the cause of the disaster.

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...

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...

In this lesson students will use color tiles to measure classroom objects.

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.
