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
Graphical Displays of Univariate Data
Students will sort data and construct stemplots, dotplots, histrograms, and frequency plots.https://education.ti.com/en/activity/detail/graphical-displays-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
Sampling Distribution of Differences
This activity covers the distribution of a difference between two independent sample proportions or two independent sample means.https://education.ti.com/en/activity/detail/sampling-distribution-of-differences
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
Proportional Flag
Students will use the concepts of similarity to create a scale drawing of the national flag, that is large enough to cover most of a football field.https://education.ti.com/en/activity/detail/proportional-flag
Set Design
Students will use similarity concepts, and the dimensions of the carvings on Mt. Rushmore to create a proportional representation of the carvings for a stage backdrop.https://education.ti.com/en/activity/detail/set-design
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
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
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
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
Banquet Meal
Students use proportional reasoning skills to increase a family-size recipe to a banquet-size recipe.https://education.ti.com/en/activity/detail/banquet-meal
Golden Rectangles
Students measure rectangles and calculate ratio between the sides. They compare the ratio to the Golden Ratio (1.618).https://education.ti.com/en/activity/detail/golden-rectangles
Thrift Store Markdowns
Students will calculate a series of discounts using increasing unit fractions.https://education.ti.com/en/activity/detail/thrift-store-markdowns
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
Making Cookies
Students will reduce a cafeteria recipe to suit a household recipe. They use compatible numbers to choose smaller measurements while retaining the original proportions.https://education.ti.com/en/activity/detail/making-cookies
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
What is a Variable?
In this lesson students evaluate expressions, write expressions that correspond to given situations, and use expressions and formulas to solve problems. Students also examine a product of the form ax for given integer values of a in terms of how the value of the product changes for a one unit cha...https://education.ti.com/en/activity/detail/what-is-a-variable-bc
What is an Equation?
In this lesson students begin by establishing the difference between an expression and an equation. Students then investigate expressions and equations to develop what it means to have a solution to an equation.https://education.ti.com/en/activity/detail/what-is-an-equation-bc
What is an Exponent?
Why are exponents useful and how do they behave? An exponent indicates how many times the base to which it refers is a factor; i.e., in , the 4 indicates that the base, 3, is used as a factor four times. This lesson focuses on how the definition can be used in a variety of situations to make sens...https://education.ti.com/en/activity/detail/what-is-an-exponent--bc
