Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

High schoolers investigate parallel and perpendicular lines. They use Cabri Jr. to construct and explore the relationships between the slopes of parallel and perpendicular lines. The drawing and measurement tools available with Cabri Jr....

High schoolers explore quadrilaterals in this geometry lesson. They will draw a quadrilateral, measure the angles, and find the sum of the measures of the interior angles using Cabri Jr. The interactive capabilities of Cabri Jr. allow...

Pupils examine the centroid of a triangle as they use Cabri Jr. to construct a triangle and its medians. The dynamic nature of the software allows learners to measure the lengths of the segments in the triangle and conjecture and verify...

Pupils investigate inscribing a circle in a triangle. They use Cabri Jr. to draw a triangle, locate the incenter, and use the distance from the incenter to a side of the triangle to inscribe a circle. The dynamic nature of the geometry...

Pupils investigate segments in a triangle by constructing a triangle using Cabri Jr. They construct segments within the triangle that lie on the midpoints of the triangle's sides. Learners then compare the slope of base of the triangle...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

Pupils explore the midsegment of a triangle in the geometry lesson. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The...

High schoolers investigate the sum of the measures of the angles of a triangle. They draw a triangle and measure the interior angles. Using Cabri Jr., learners find the sum of the measures of the interior angles. The lesson provides an...

Students discuss transition metals, where they are located on the periodic table, some of the element in the group, and some characteristics of the group. They work in groups to conduct an experiment in which they mix transition metals...

Learners calculate the sides of right triangles in this trigonometric ratios activity. They use Cabri Jr. software and TI-83 or TI-84 calculators to find the side lengths and their ratios to each other for various triangles. The provided...

Young scholars construct two dimensional models to illustrate squared numbers. In this geometry lesson, students use graph paper and an x/y axis to build squares exponentially. Young scholars identify powers and relationships between...

Learners create tornado proof buildings.  In this weather activity, students review tornadoes, discuss creation of tornado proof buildings, and learn about the Fujita Scale of Tornado Intensity.  Learners research tornado proof...

Students complete a unit of lessons on rocks and minerals. They conduct research, write e-mail questions to geologists, write daily journal entries, label maps demonstrating types of rocks/minerals found, and create a web page that...

Young scholars use newspapers and the internet to discover what the IMF does. They work together in groups to brainstorm occupations which need another language to be spoken. They also examine data related to trading among countries.

Pupils select a country and conduct research on the culture, population, geography, and government of their country. They conduct research using the Internet and a variety of resource books, and write and publish a report that includes...

Students research the United States and discover its different climate zones, geographical features, animal life, and various cultures. Students complete a research chart using books, encyclopedias and the internet and present their...

Eighth graders complete seven work stations that highlight math activities while they focus on the rules for Internet use and classroom rules for working in cooperative groups. After completing the activities, they complete a self-...

Students study the geography of the United States of America. Students write letters, create travel brochures, make maps, graph population numbers, read fiction and nonfiction selections, complete KWL charts, and watch films.

Students follow the appropriate sampling protocol and take two measurements of a local water source. These measurements are Transparency and Temperature. This info about local land use and/or water chemistry issues may require further...

Students investigate the force of compression and how it acts on structural components through a hands-on group project. They use everyday products such as paper, toothpicks, and tape to construct a structure that will support the...

First graders measure how a shadow changes over the course of a day. They write about what they would do if they lost their shadow, and make silhouettes of themselves. Students make up a shadow dance and read stories about shadows.

Students will investigate the differences in conductivity of materials, design a variety of complete circuits, and observe the differences between the manner in which light is produced in an incandescent light bulb and an LED.
