Pupils explore linear functions in this lesson when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of slope...

Students calculate the distance between two points. In this geometry lesson, students define the meaning of the distance between parallel lines. They find the point of intersection of other lines.

Learning how to define vocabulary words related to solving parallelograms will assist your learners in identifying different parallelograms. They use the navigator to view different shapes created by moving the parallelogram around.

Find the length of an arc. Students relate central angles to the area and length of a sector and graph circles on the TI to make predictions.

Students perform transformations on their graphs. In this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.

Students examine a sample budget and categorize the entries as a group. Then in small groups they convert budget category totals to percents and degrees to make a circle graph related to a sample budget.

Teach your learners how to investigate the relationship between a central angle and an inscribed angle which subtend the same arc of a circle. The dynamic nature of Cabri Jr. provides opportunity for conjecture and verification.

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...

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...

Pupils investigate similar triangles and proportions as they make conjectures about the length of sides of similar triangles. For this lesson, have your class construct similar triangles using Cabri Jr so that they share a common vertex.

In this magnetic storms worksheet, students use a graph of data collected over time showing the magnitude of a magnetic storm. Students use the data to solve 6 problems about the graph and they determine the strength of the storm at...

Young scholars explore the concept of the formula for distance. In this formula for distance lesson, students time battery operated cars with constant velocity over 15 meters. Young scholars use the distance = rate x time formula to...

Students create a map. For this direction and distance lesson, students come up with familiar places in the community and calculate the distances from these places to the school. Students create a map that displays these places and their...

Students explore the concept of sine. In this sine lesson, students create a sine graph from tooth picks. Students create a unit circle with tooth pick length radius. Students then take the tooth picks from the unit circle and put them...

Students calculate the distance in light years. In this geometry instructional activity, students solve problems involving distance, using the distance formula. They rewrite big numbers using scientific notations and apply their...

Students work with Ellipses in Algebra II. In this algebra lesson, students solve an equation with a radical expression. They graph ellipses and write an equation for them.

Students graph lines in a coordinate plane. For this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They classify the lines as parallel or perpendicular and write an equation of a given line.

Students define and identify transformation and rotation. In this geometry lesson, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.

Second graders demonstrate understanding of symmetry and identify objects that have symmetry. They use a mirror to get a visual illustration of what symmetry is. They create a collage of symmetrical pictures they find in magazines.

Students study hurricanes; in particular, what they look like, how they are formed, how they are categorized, how they are named, and how they are tracked. They examine the science of hurricanes as well as the mathematics of hurricanes.

Learners survey their school to get ideas for how to make the school more environmentally friendly. In this environmental lesson plan, students collect data from other learners and teachers. They use the data to create graphs and present...

Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.

Students investigate how to design and build items with a focus on structural strength as an engineer would. They complete a truss-building project as a final assessment.

Middle schoolers study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Middle schoolers complete worksheets based on...
