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
Properties of Parallelograms

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
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
Number and Operation Sense: Rational Numbers
Students learn to use the calculator to collect a set of data in order to identify patterns that illustrate important rational number concepts: the relationship between rational numbers and division, and equivalent fraction and decimal forms for rational numbers.https://education.ti.com/en/activity/detail/number-and-operation-sense-rational-numbers

Looks Right
Students use the Cabri Geometry II Plus software to determine which given triangle retains its basic shape after its vertices are dragged around the screen.https://education.ti.com/en/activity/detail/looks-right
Match the graph
Students use the Cabri Geometry II Plus software to reflect points from a graph across the axes.https://education.ti.com/en/activity/detail/match-the-graph
Area of Triangle
This Cabri Geometry activity enables students to review the relationship between the height of a triangle and its perimeter and area.https://education.ti.com/en/activity/detail/area-of-triangle
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
Exploring the Unit Circle
In this activity, students explore the properties of a unit circle and its mapping functions.https://education.ti.com/en/activity/detail/exploring-the-unit-circle
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
Homestead-Miami Chase Activity
In this activity, students will investigate whether it is better to take the shortest path or the fastest path.https://education.ti.com/en/activity/detail/homesteadmiami-chase-activity
Modeling Median Incomes
