Young scholars investigate triangles and congruences. For this geometry lesson, students differentiate between inductive and deductive reasoning. They differentiate between similar and congruent triangles.

Students differentiate between ellipse and hyperbola. In this algebra lesson, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Students engage in a activity that focuses on analytic geometry. The activity asked them to apply skills of relating equations when plotting them on the coordinate plane. Students construct the equations using specific criteria and apply...

Students investigate circles and compound locus. In this geometry lesson, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Students identify the properties of a dragon curve. In this geometry lesson, students identify sequences and patterns as they solve fractals. They investigate patterns found in nature.

Develop a more precise definition of similar. The lesson begins with an informal definition of similar figures and develops the need to be more precise. The class learns about dilations and uses that knowledge to arrive at a...

Show learners how to develop a procedure for solving equations using radicals with the fifth lesson of the 25-part module that challenges learners to use properties to solve multi-step quadratic and cubic equations. Individuals round out...

Get a line on the snakes. The assessment task requires the class to determine the species of unknown snakes based upon collected data. Individuals analyze two scatter plots and determine the most likely species for five...

Students complete worksheets involving rotational symmetry. In this geometry lesson, students complete worksheets to identify rotational symmetry and rotations. They compare and contrast rotated figures. Students examine the relationship...

Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams lesson, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...

Students create, transform, and critique their own piece of artwork. In doing this lesson, students get more experience working with angles, lines, and measurement. They gain experience seeing, and creating their own patterns and shapes.

In this curvilinear coordinate activity, students compute the Jacobian of standard transformations to Cartesian coordinates from polar, spherical and cylindrical coordinates. They identify the determinant of the Jacobian matrices. This...

In this matrix inverse activity, students identify a matrix which when multiplied by a coefficient matrix, it transforms into an identify matrix. They use the Gauss-Jordan elimination process to find an inverse matrix. This four-page...

Students solve problems using equations and properties of integers. In this algebra lesson, students solve problems using ratio and proportion and graph their answers on a coordinate plane. They solve word problems using geometry.

The task at hand is to partition a hexagon into two, four, and eight congruent figures. Make sure to give your wizards a sheet of triangle grid paper on which to decompose the hexagons. Have them explain which rotations, reflections, or...

Just about every public building that your students are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean Theorem,...

Fourth graders investigate the concept of geometric patterning. They create their own patterns with a few basic requirements. The patterns must illustrate the concepts of flipping, 90 and 180 degree rotations. The collages also consist...

After watching a video of Peter and the Wolf, and identifying the instruments used to represent each character, class members use rhythm instruments to represent the actions in the song, "What Would I do."

Young hydrologists observe a waterwheel which helps them investigate the transformations of energy that occur when the blades of a hydro-turbine are turning. They work together in pairs and pretend to be engineers who are building a new...

Watch as matrices break networks down into rows and columns! Individuals learn how a network can be represented as a matrix. They also identify the notation of matrices.

After reading Elie Wiesel's Night, watching the movie Life is Beautiful, and researching World War II, class members write a comparison essay on the book and film. This includes a prior knowledge activity, discussion in whole and small...

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

Eighth graders investigate the concept of tessellations and transformations. They create patterns to demonstrate and practice the skill. Students write a description of the pattern for others to interpret. The pattern is assessed...
