This activity investigates the use of the Inequality Graphing App of the TI-83 Plus/TI-84 Plus to solve a linear programming problem.

The student will use the TI-83 Plus/TI-84 Plus to calculate confidence intervals for proportions.

Here's a very detailed, step-by-step activity for students to do to learn about the relationship between the factored form of a polynomial function and its graph. Calculator instructions for the TI-83 are given, right down to the screen...

Charlie uses parametric equations of projectile motion to figure out where to look for a fired bullet in the "Convergence" episode of the show NUMB3RS. The lesson plan includes a student page complete with keystroke instructions for the...

Students will plot points in a coordinate plane and reflect those points across the axes using a MIRA and then using the graphing calculator STAT, STAT PLOT, and GRAPH menus graph the image on the graphing calculator screen.

In this activity, students investigate a pattern using the constant function on the calculator, record the results displayed on the calculator, and describe how the constant key works.

Based off of the hit television show NUMB3RS, this lesson simulates a closed market in which goods are bought/sold for money. After the five minute activity, students calculate the amount of money dispersion, and based off of this...

After studying the USA TODAY Snapshot? "West Nile killing more people,"students will compare the number of West Nile cases in the United States over the past three years. From the data, percent increases and decreases from year to year...

In this activity, students use the statistical features of the calculator to calculate statistical results, perform regressional analyses, and graphically display statistical data.

In this activity, students use the CellSheet Application to calculate accrued interest on a principal. During the activity students solve a problem to calculate the interest on a principal, for a specified period.

Based off of the hit television show NUMB3RS, this lesson, designed for upper-level high school students, has students linearize the data describing the force of a magnet at various distances. While it is assumed students already know...

Based off of the hit television show NUMB3RS, this lesson introduces students to one way of defining the strength of an encryption (called "Entropy"). In the lesson, students learn how to calculate the entropy of a given code, and then...

In this activity, students' will use a motion detector to record the distance versus time data for the simple motion of a walker. They will calculate velocity from this graph and compare it with the velocity graph generated by the...

In this activity students will measure various body parts looking for the golden ratio. The teacher will collect the various measurements from the calculators and send an augmented list to the students calculators. Students will then...

Using the Cabri Jr. App and the 83+/84+ calculators, students explore and calculate the various trig ratios. This is an easy construction but be sure to allow plenty of time for exploration and completion of the worksheet questions in...

Based off of the hit television show NUMB3RS, this lesson has students try to emulate a time vs. distance graph on their graphing calculator using the CBR2. Next, the CBR2 is "swept" across an area in which three students are standing to...

This App allows teachers and students to create electronic flash cards to use as a study tool for quiz or test review. Students can also download prepared flash cards on many topics onto their graphing calculator.

Students use the calculator to determine the amount of money that will accumulate in a savings account, if every month a certain sum is deposited in the account. They explore the use of the constant function key on the calculator to make...

In this activity, students' will use a pair of motion detectors to record the cartesian coordinates of a rod moving in a star-shaped pattern and calculate the distances moved between the vertices of the star. They also compare these...

In this activity, students use measuring tools and calculators to make half-sized drawings of themselves.

Based off of the hit television show NUMB3RS, this lesson has students create ways to check their calculations against the three most common checkbook errors. After students have completed this part of the lesson, they then solve a good...

This activity Pendulum from Holt Physics Chapter 11 Vibrations and Waves uses the calculator and the VIB program calculate the period of a pendulum on different planets.

Students use a graphing calculator to explore graphs of equations in slope-intercept form.

Based off of the hit television show NUMB3RS, this lesson has students calculate the probability that a spider web will catch a fly. The webs are modeled as standard geometric figures (circle, rectangle, triangle), and assumptions are...
