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 lesson provides ample opportunity for learners to conjecture...

Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.

Young mathematicians explore the concept of triangles as they construct altitudes of triangles to find the orthocenter. Learners construct their triangles using Cabri Jr. on their graphing calculators and find that the altitudes of a...

Learners explore the measures of the angles of a triangle in this geometry 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 interior and...

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.

Learners explore the difference between a construction and a drawing. They focus on various ways to construct different types of triangles. The lesson is an application of Cabri Jr. and reinforces the difference between a constructions...

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 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...

Students analyze midsegments of triangles in this instructional activity. They use Cabri Jr. software to observe the relationships between interior angles and midsegments of triangles. Specific instructions for creating this...

Learners calculate the sides of right triangles in this trigonometric ratios lesson. 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...

High schoolers investigate properties of the four centers of a triangle and explore a special property of the circumcenter and orthocenter of a triangle. This lesson requires the use of Cabri, Jr.

High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...

Students differentiate between metallic and non-metallic sounds. In this music lesson, students listen to the audio clip of "March" and march in time with the music. Students identify the metallic sounds in the music piece. Students...

Tenth graders solve problems using the correct tools. In this geometry lesson plan, 10th graders solve problems by constructions and graphing. They use a protractor, compass and straight edge to help create angles and bisectors. The...

First graders identify vegetables and flowers that can be grown from seed.  In this seed sowing lesson, student learn the correct spacing and planting of various types of seeds. Students label plants. 

Tenth graders explore the properties of the incenter of a triangle. In this geometry lesson, 10th graders construct a triangle and the angle bisectors of each angle. The dynamic properties of Cabri Jr. allow students to locate and...

Students explore participial adjectives. In this social studies lesson, students select the participial adjectives within a passage. Students write about an event using participial adjectives.

Students practice their keyboarding skills. For this typing lesson, students use interesting stories to practice their skills. They practice throughout the semester and then monitor their improvement.

Students fill out a timecard of family activities in Microsoft Excel. In this Excel lesson plan, students use the program to fill in times they do various activities with their families.

Young scholars complete an Excel project on tessellations. In this technology and math lesson, students discuss tessellations and their occurrences in nature. Young scholars use the Excel computer program to create tessellations.

Young scholars create a graphic organizer to study animal characteristics. In this animal characteristics lesson plan, students use a program in Microsoft Word to create a brainstorm about different animal characteristics.
