Fourth graders examine patterns that influence population density in the various regions of California. The unit's three lessons utilize graphic organizers for the interpretation and presentation of data.

Middle schoolers explore the relationship between nature and architecture. In this cross curriculum history, culture, and architecture lesson, students observe and discuss structures visible in nature. Middle schoolers view websites in...

Students collect data on the favorite seasons. In this data collection and analysis lesson, students learn about displaying data on charts and graphs. They collect data about the favorite seasons of the children in their class and...

Students solve quadratic function by completing the square. In this algebra lesson, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.

Students solve problems using reasoning techniques, identify the validity or non-validity of problems and use deductive reasoning for problem resolution.

Students discuss tangram vocabulary, and act out slide, flip, and turn. They observe tangram puzzles on a web page, and solve their own tangram puzzles.

Pupils examine the concepts of symmetry, rotations, reflections, translation, dialations, and tessellations and apply them to indigenous art. They also do Internet research and create artwork (painting, pottery, computer graphic design).

Fourth graders explore and examine through hands-on experience and reasoning the concept of fractions. They solve problems involving multiplication and division of whole numbers and addition and subtraction of simple fractions and decimals.

Students calculate the area and perimeter of a basketball court. In this geometry lesson, students differentiate between similarity and congruence of geometric objects. They test conjectures and use it to solve problems.

Students discover which regular polygons can be used to tile a plane.

Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.

Students are introduced to the notion of a complex number and function iteration in order to motivate the discussion of Julia sets and the Mandelbrot set.

Students measure and predict the behavior of a fractal.  In this investigative lesson students divide into groups, and participate in an activity that includes drawing triangles and coloring vertices. 

Students construct a set of tangrams. In this geometry lesson, students read the book, Grandfather Tang's Story and retell the story using tangrams. Students construct their own set of tangrams using the included worksheets.

Students investigate motion using a CBL. In this algebra lesson, students collect and graph data on a coordinate plane. They define and identify amplitude and period of conic graphs.

Students practice multiples of the numbers 1-9 and different manipulative skills such as clapping and snapping.

Fifth graders demonstrate their understanding of tessellations by watching a teacher prepared Powerpoint presentation and completing an activity. The students work independently to identify tessellations.

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Students form rectangles by using tiles, measure area and perimeter by counting. They discover and apply rules for measuring perimeter.

Students use the relationship between volume and surface area to construct a box out of a piece of paper that maximizes volume using a table and by using graphing and calculus techniques.

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

Tenth graders investigate three different sets of data that relate temperature to another variable in the physical world. These illustrate linear, inverse and exponential relationships.

Students access the Internet to find information on current hurricanes. They get locations, speeds, and air pressures and then plot the location of the hurricane on a hurricane-tracking map. They also access the FEMA website to solve...

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...
