Using TI-Nspire, scholars rewrite quadratic expressions by completing the square. They change the equation into vertex form.  By the end of this lesson, they should be able to change any quadratic equation into vertex form. 

Using elimination to find the point of intersection of two lines, students learn to solve systems of equation. They graph their solutions and use the TI to verify the solution.

Pupils explore the concept of distance and time as they use a CBR to mimic distance v. time graphs. Learners walk towards and away from the monitor to create various distance v. time graphs, then discuss what motion creates certain graphs.

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.

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.

Pupils practice sample questions from the AP Calculus Exam. They solve calculus problems involving bounded regions, integration, derivatives, and limits. They then answer free response and multiple choice questions on the above mentioned...

Learners differentiate between expression and equation by evaluating integers and observing the difference. They use the TI to see the steps to solve problems.

Your class will use a TI calculator to drag vertices of rectangles and triangles to observe what happens to ratios of pairs of sides within each figure. They will apply the definition of similarity to identify similar shapes. The lesson...

Nested triangles have been created so that they share a common vertex and vertex angle. Learners drag the endpoints of the side that is opposite the common angle to discover the conditions that make the nested triangles similar. When...

Have your class solve equations using matrices by teaching them how to factor systems of equation to identify the point of intersection. They create their matrices on the Ti and perform row operations to simplify.

Students model a paleontologist's activities. They identify dinosaur bones and reassemble them into a skeleton of an extinct reptile.

Middle schoolers write a paper about how their life would be different if fractions, decimals and percents did not exist. The teacher leads a discussion after the papers are written.

Pupils explore the concept of pyramids. They determine if two sides of a pyramid are perpendicular using a graphing calculator, then discuss parallel and perpendicular lines and how to determine if two lines are parallel or...

Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.

Students examine the functions of the kidney and its place in the urinary system. They discuss how astronauts go the bathroom in space, examine labeled diagrams of the urinary system, and draw a large scale drawing of the excretory...

Students describe the five senses. They perform an investigation using sensory organs associated with each of the senses. Students identify, describe and extend repeating relationship (pattern) found in common, objects, sounds and...

Students examine statistics about kidney transplants. In this current events instructional activity, students discuss the premise of the reality television show, "Big Donor Show." Students also discover the functions of the kidneys as...

Students observe and discuss a vacuum cleaner model of a baghouse to better understand how this pollutant recovery method functions in cleaning industrial air pollution. They give examples of when the use of a baghouse is appropriate,...

Students create digital mosaics. In this visual arts lesson, students discover the attributes and history of mosaics in a teacher-led discussion. Students use an educational program to make their own digital mosaics.

Students examine the use of electronic mail. In this electronic mail lesson, students determine how to use different e-mail programs and how they access information using this medium. They discuss how e-mail differs from regular mail and...

Students explore the primary function of the respiratory system in multiple activities. For this respiratory system lesson, students build a model of the respiratory system to investigate how the lungs work.

Students identify long and short term goals. In this perseverance instructional activity, students discuss the difference between short term and long term goals. Students categorize their personal goals as short or long term. Students...

Students design a system that will move their glass product across a room in the plant. They must move the product 12 feet and their items cannot fall off at any time.

Students examine nautical navigation and discover the differences between nautical charts and other types of maps or charts. Students practice setting a course, taking a bearing, and dead reckoning. This gives students an example of...
