Who Started It All? The Spread Of Disease
Students predict the spread of disease to be exponential. They then do a hands on "sharing of bodily fluids" and see the actual data and compare these results to the projected model. You actually see the number of infected after each sharing to see the shift of the model easier. Written to be c...https://education.ti.com/en/activity/detail/who-started-it-all--the-spread-of-disease

Comparing Costs
Students will solve a problem using division with an integer quotient and remainder, division with the quotient in fraction form, and division with the quotient in decimal form and compare the results.https://education.ti.com/en/activity/detail/comparing-costs
Coast to Coast with Alice
Students learn to solve a real-world problem comparing automobile travel in the early 1900s and travel today. They follow the route taken by Alice in 1909 from New York City to San Francisco and determine how long the trip would take today.https://education.ti.com/en/activity/detail/coast-to-coast-with-alice
Transmission Lines
Describes how to calculate the characteristic impedance and phase velocity on transmission lines. Steady state transmission line behavior and simple matching concepts are included also. The functions reflcoef(), lineleng(), zin(), yin() and vswr() are created.https://education.ti.com/en/activity/detail/transmission-lines
Vector Calculus
Describes how to use the TI-89 for differential and integral calculus. The differential operations illustrated include gradient, divergence, curl, and Laplacian. Line and surface integrals also are included. The functions cordchk(), grad(), div(), curl() and lap() are created in this chapter, ...https://education.ti.com/en/activity/detail/vector-calculus
Convolution
Shows the convolution of two functions. To simplify the details, the functions are finite, piecewise, and continous.https://education.ti.com/en/activity/detail/convolution
Crunching Numbers
Students learn to build and add two digit numbers. They connect number words and numerals.https://education.ti.com/en/activity/detail/crunching-numbers
Design a Quilt
Students learn to use pattern blocks to build a two dimensional design, and use the calculator to determine the value of the design.https://education.ti.com/en/activity/detail/design-a-quilt
Antennas
Describes how to perform basic antenna and radiation calculations with the TI-89. Antenna patterns, radiation resistance, radiation integrals, and phased array patterns are included.https://education.ti.com/en/activity/detail/antennas
Lifting a Lion
In this activity, students will practice solving a real-world problem. Using a toy lion and a lever, students first discover how much work is needed to raise a toy lion. They will then use proportions to determine the force needed to lift a real lion.https://education.ti.com/en/activity/detail/lifting-a-lion
Let Me Count the Ways
Students will make predictions about the number of ways to make eleven with two or more addends. They will investigate patterns with these addends with the help of manipulatives and the calculator.https://education.ti.com/en/activity/detail/let-me-count-the-ways
It's the Place that Counts
Students learn to add using place-value material and a calculator. They make connections between base-ten numerals and the quantities they represent.https://education.ti.com/en/activity/detail/its-the-place-that-counts
In the Range
Students will interpret the rounding involved in measuring to identify the possible range of a given measurement.https://education.ti.com/en/activity/detail/in-the-range
Helping Hands
Students make their own finger signs for the numbers from zero to ten. Students relate each finger sign to its number name and numeral. They use the numeral keys and scrolling feature of the TI-10 to enhance the concrete-symbol connection and sequencing of numbers.https://education.ti.com/en/activity/detail/helping-hands
Fraction Forms
Students will compare the results of using division to create fractions under the different mode settings for fraction display and make generalizations from the patterns they observe.https://education.ti.com/en/activity/detail/fraction-forms
Food for Thought
Students learn to count in tens up to 100. They also learn to build 2-digit numbers.https://education.ti.com/en/activity/detail/food-for-thought
Yards of Tin
Students solve a problem involving surface area of cylinders. They find the surface area and the amount of tin needed to make the cylindrical parts of ten long open pipes.https://education.ti.com/en/activity/detail/yards-of-tin
Recurring Remainders
Students will use the calculator to investigate the patterns formed by remainders in whole-number division.https://education.ti.com/en/activity/detail/recurring-remainders
Bats Triangular
Students use manipulatives to construct a pyramid. The manipulative pyramid then becomes the basis students use to construct a pictorial representation of a pyramid. The TI-10 is used to show symbolic representation of students actions and also aids students in viewing the developing pattern.https://education.ti.com/en/activity/detail/bats-triangular
Area Patterns
Students investigate patterns in ordered pairs generated by constructing a sequence of similar shapes. They will then use the patterns and the calculator to predict the number of blocks it will take to build a specific shape in the sequence.https://education.ti.com/en/activity/detail/area-patterns
Analyzing Number Cube Sums
Students extend their understanding of theoretical probability and patterns. They use number cubes, to build awareness that a fraction and its decimal and percent representation on the calculator are "close," but not necessarily equal.https://education.ti.com/en/activity/detail/analyzing-number-cube-sums
Amazing Appetites
Students learn to count and solve original word problems. They learn to add by combining sets and subtract when removing the set. They use manipulatives to reflect the reasoning used in problem solving.https://education.ti.com/en/activity/detail/amazing-appetites
