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
How Salty Is It?

Hat Trick
Students learn to solve a real-world problem in economics. Students get to understand how surveys often use a sample of people rather than all of the people involved. They also learn how to make decisions based on the results of a sample survey.https://education.ti.com/en/activity/detail/hat-trick
Probability as Relative Frequency
In this activity, students use simulation to justify the concept of the Law of Large Numbers. They understand that as the sample size increases, the relative frequency of which an event occurs approaches the probability of that event happening. Students investigate the binomial and geometric prob...https://education.ti.com/en/activity/detail/probability-as-relative-frequency
Confidence Intervals
Students understand the confidence intervals for a proportion and for a mean. They also examine the confidence intervals for the difference between two means, and for the difference between two proportions.https://education.ti.com/en/activity/detail/confidence-intervals
Describing Categorical Data - Advanced Placement
Students categorize data using tables and bar charts. They also determine relative frequencies.https://education.ti.com/en/activity/detail/describing-categorical-data--advanced-placement
The Normal Distribution
Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.https://education.ti.com/en/activity/detail/the-normal-distribution_1
Exploring Bivariate Data
Students graph scatter plots and understand the concepts of correlation and least-squares regression. They also perform transformations to achieve linearity in the data plot.https://education.ti.com/en/activity/detail/exploring-bivariate-data
Tests of Significance
Students understand how tests of significance can be performed with confidence intervals. They use a simulation to clarify the meaning of a hypothesis. Students examine large sample tests for a proportion, mean, difference between two proportions, and difference between two means. They also study...https://education.ti.com/en/activity/detail/tests-of-significance
Summarizing Distributions of Univariate Data
Students understand statistical concepts like center of data and the amount of data variation from the center. They calculate the measures of the center of a distribution and the measures of spread for the data collected as a list. Students also create boxplots for the data. They examine the effe...https://education.ti.com/en/activity/detail/summarizing-distributions-of-univariate-data
Special Cases of Normally Distributed Data
Students perform single and two-sample t procedures to investigate special cases of normally distributed data. They explore inference for a least-square regression line, including the confidence interval.https://education.ti.com/en/activity/detail/special-cases-of-normally-distributed-data
So Many Zeros!
Students will explore standard and scientific notation representations of numbers. Students will also discuss the need for different representations of very large or small numbers, and they will see real-world examples of these representations.https://education.ti.com/en/activity/detail/so-many-zeros
Creating Word Problems
Students write word problems based on the whole numbers generated by the calculator. They decide on an operation to solve the problems. Finally, they analyze the problems to determine the problem characteristics when using operations on whole numbers.https://education.ti.com/en/activity/detail/creating-word-problems
Dilation
Students use the Cabri Geometry II Plus software to investigate the geometric property of dilation. They vary the scale factor and examine the effect on the dilation of a triangle.https://education.ti.com/en/activity/detail/dilation
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
What's the Fastest Way to Get Rich?
Students investigate exponential growth and discover patterns by exploring different scenarios involving money. They will learn how repeatedly doubling, or multiplying by two, can also be expressed exponentially.https://education.ti.com/en/activity/detail/whats-the-fastest-way-to-get-rich
In Round Numbers
Students will develop and test rules for rounding whole numbers and decimal fractions. They will use the information to solve real-world problems.https://education.ti.com/en/activity/detail/in-round-numbers
Absolute Values
Students will review the set of integers along with the addition and subtraction of integers using a number line. Then, they will learn that the absolute value of a number is defined as the distance from zero. Students will learn how to interpret the absolute value symbol algebraically, as well a...https://education.ti.com/en/activity/detail/absolute-values
