students take part in a variety of writing exercises about the most important pastime or activities in which they participate and the personal growth gained through this participation.

Students, in groups, develop math lessons for younger students that each stems from a popular student story. Group members individually develop lessons for other subject areas based on their group's story, creating interdisciplinary units.

Students compare the colloquial definition of temperature with the scientific definition. They, in groups, then explore the changes of water under different temperatures and calculate and compare their findings on three different...

Students describe in words and graphic displays the elevation or depression profile of sections of Mars' Olympus Mons and/or Valles Marineris. They explain how orbiting spacecraft build up global maps one data slice at a time.

Students recite Willie Nelson's lyrics in one voice and then analyze their tone and vocabulary usage. They research Willie Nelson's history and dramatize the song: "On the Road Again."

Students reflect in their journals about an everyday object they take for granted. After reading an article, they examine what a cook's tools can reveal about their life. In groups, they research everyday objects and write a museum...

Students analyze why the census is important and the benefits of it. Determine rights and responsibilities in real life situations. They are divided into groups and take a mock census of a list of teachers and students each. Results of...

Through learning how to examine linear, quadratic, and exponential functions, students explore the effects of changes in parameters on the graphs of linear, quadratic, and exponential functions.  The lesson is designed to be a...

Learners explore how changing an angle in a triangle changes the ratio of the sides. They also explore how changing the sides can make changes to an angle in a triangle. Finally, they determine how two different pairs of sides, in the...

Pupils detect the waveform of musical notes to determine the code for the "safe" in this forensics simulation lesson. They use a microphone and tuning forks along with Vernier EasyData on their graphing calculator to analyze five musical...

Learners investigate the derivative of a function.  In this calculus instructional activity, students explore the derivatives of sine, cosine, natural log, and natural exponential functions.  The instructional activity promotes...

Young learners apply divisibility rules to determine if a number is a factor of another number. They discuss what numbers are factors of another number and identify patterns using divisibility rules.

Using Cabri Jr. students construct a circle and determine the equation of the circle they drew by finding the center and the radius. Students use the distance formula to derive the equation of their circle.

Learners investigate the properties of segments formed which chords, secants, and tangents, intersect. The dynamic nature of Cabri Jr. allows students to form and verify conjectures regarding segment relationships.

High schoolers differentiate lines and angles using betweenness in this geometry lesson. They differentiate angles and lines using Cabri Jr. and analyze the data and make conjecture.

Pupils explore the concept of angles and transversals. They construct parallel and non-parallel lines cut by a transversal using Cabri Jr. Learners then determine which angles are congruent and the relationship of angles when two lines...

High schoolers construct perpendicular bisectors using Cabri Jr. on their graphing calculator. They then construct conditional statements about perpendicular bisectors along with their converse, inverse, and contrapositive.

Learners use technology to determine the shortest between two points in a plane. They are required to support their analytic explanations with visual illustrations.

Young scholars investigate the properties of quadrilaterals formed by angle bisectors of a given quadrilateral and quadrilaterals formed by the medians of quadrilaterals. This Cabri Jr. lesson provides opportunity for conjecture and...

Learners investigate the area of various figures. They construct triangles and quadrilaterals using Cabri Jr. and discuss the relationships between different angles, side lengths, and figures.

High schoolers explore the concept of quadrilaterals as they find the midsegments of quadrilaterals using Cabri Jr. on a graphing calculator. They find midpoints, slopes, angles, and distances of lines and angles.

Pupils investigate the properties of a rotation as they use technology (Cabri, Jr.) to observe the relationship between the pre-image and the image formed by the rotation. The instructional activity provides ample opportunity for...

Learners explore the measures of the angles of a triangle in this geometry instructional activity. They use Cabri Jr. to investigate the sum of the measures of the interior angles of a triangle, and examine the relationships between the...

Learners investigate the special properties of an altitude, a median, and an angle bisector and explore how these special segments divide the area of a triangle. The dynamic nature of Cabri Jr. allows pupils to form and verify conjectures.
