Transient Circuit Analysis: Symbolic
Describes how to use the differential equation solver, deSolve(), to solve first- and second-order circuits containing resistors, capacitors, inductors, DC sources, and exponential sources. It also shows how to graph the solutions and find the zero crossing and peak values.https://education.ti.com/en/activity/detail/transient-circuit-analysis--symbolic
Busy Hands
Students will make their own finger signs for the numbers from zero to ten. Students will relate each finger sign to its numeral and then explore number sentences using the calculator.https://education.ti.com/en/activity/detail/busy-hands
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
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
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
Financial Calculations
Describes how to use the TI-89 to calculate interest, present worth, loan repayments and so forth. These methods utilize the time-value-of-money.https://education.ti.com/en/activity/detail/financial-calculations
Marching Columns
Students investigate constructing arrangements of different numbers of manipulatives into equal groups. They learn to use mathematical language, identify patterns with numbers, recognize the commutative property, and transfer the arrangements made with manipulatives to grid paper.https://education.ti.com/en/activity/detail/marching-columns
How Salty Is It?
Students learn to solve a real-world problem involving salt water. Students will determine the amount of sea salt needed to turn an aquarium into a simulated salt-water environment. They also experiment with items and check their buoyancy in water with varying salt concentrations.https://education.ti.com/en/activity/detail/how-salty-is-it
How do You Measure Up? (with the TI-10)
Students measure weight, height, and length with the help of a balance, scales, rulers, yardstick, and tape measures. They use their TI-10 to find proportions and to round off answers to whole numbers.https://education.ti.com/en/activity/detail/how-do-you-measure-up-with-the-ti10
Football Scores
Students will determine the possible combinations of scoring events in a football game to reach a specific end score.https://education.ti.com/en/activity/detail/football-scores
Comparing Distributions of Univariate Data
Students compare univariate data distributions using statistical concepts like boxplots, stemplots, and histograms.https://education.ti.com/en/activity/detail/comparing-distributions-of-univariate-data
Sampling Distributions
Students studies the distribution of sample proportions with a simulation. They find small sample size leads to skewed distribution and as the sample size increases, the distribution becomes more normal.https://education.ti.com/en/activity/detail/sampling-distributions
Fractions and Skittles
Students will predict how many of each color will be in one pack of skittles before they open the package. Once they open the package, they will determine how close their predictioins are to the actual amount. Students then will come up with ratios and averages.https://education.ti.com/en/activity/detail/fractions-and-skittles
Stepping Stones
Students use volume formulas and proportional reasoning to calculate the amount of concrete needed to make stepping stones of a specific size.https://education.ti.com/en/activity/detail/stepping-stones
Dividing Notes
Students create an altered musical melody by dividing fractions. They compute the value of notes in terms of fractions and make their sum equal to the time signature.https://education.ti.com/en/activity/detail/dividing-notes
Thrift Store Markdowns
Students will calculate a series of discounts using increasing unit fractions.https://education.ti.com/en/activity/detail/thrift-store-markdowns
Finding the area of a perfect polygon.
To find the area of a "regular polygon."https://education.ti.com/en/activity/detail/finding-the-area-of-a-perfect-polygon
Pizza Extravaganza
Students will conduct a survey of the class to determine favorite pizza toppings. They use this sample information to predict the preferred toppings for the school and use the TI-15 to help them with the calculations to plan a school-wide pizza party.https://education.ti.com/en/activity/detail/pizza-extravaganza
Meal Manager
Students will use percentages and proportional reasoning skills to solve problems.https://education.ti.com/en/activity/detail/meal-manager
Building Expressions
In this lesson students view expressions as objects in their own right and interpret the form and structure of an algebraic expression. Students focus on comparing expressions and establish a foundation for the definition of equivalent expressions. Students also consider how to verify that expres...https://education.ti.com/en/activity/detail/building-expressions-bc
