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...

Learners solve geometric problems with algebra and graphing in this lesson plan. They will prove the bisectors theorem using the Cabri Jr. application, which requires Cabri on their TI.

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...

Students explore the length of an n-dimensional vector.  In this Algebra II/Pre-calculus lesson, students investigate an expansion of the Pythagorean Theorem to n-dimensional space. 

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 lesson. They use Cabri Jr. software to observe the relationships between interior angles and midsegments of triangles. Specific instructions for creating this lesson in Cabri Jr. are...

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...

Learners investigate surveying in this secondary mathematics lesson. They will explore a real world application of geometry and trigonometry as they create a plot plan using a geometry utility and calculate the area of the land parcel.

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

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 instructional activity 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...

Learners use the CABRI application for their graphing calculator to rotate, translate, and reflect triangles. They use graphing calculators and follow detailed directions to manipulate triangles in specified ways. There are three...

Learners investigate properties of the unit circle using sine, cosine and tangent. They analyze the answers to questions about the unit circle based on a right triangle.

Learners determine the trigonometric relationships within a triangle as they construct a right triangle on the Ti-89. They find the sine, cosine, and tangent of various angles of their triangle construction.

In this astronomy activity, students draw the shape of the moon as it appears in the sky each night for three weeks. With their drawings they include the moon phase and any unusual characteristics they observe.

For this environment worksheet, students distinguish between UV-A, UV-B, and UV-C radiation and explain. Then they list various explanations of the source of ozone depletion. Students also describe why an increase in smog ozone does not...

In this consonant blends word search, students locate 10 words that begin with "sm." There is a word bank for students to use for this easy poem.

In this holiday worksheet, students create a calendar highlighting special days of the year. They complete a description for each day in a short answer format.

In this science worksheet, students gather in-depth information dealing with climate change over the next century. They analyze the grid to determine the average time difference between peaks in the temperature history for the last...

In this literature based worksheet, students read the poem "Fluttering Butterflies," color the picture, underline the rhyming words and then on the lines provided, write the rhyming words on pages two through four several times.

In this Spring worksheet, students read a poem about a butterfly. Students color an illustration and underline rhyming words. Students also write the rhyming words and compose their own Spring poem.
