a-MAZE-ing Secret Paths
Students learn to add and subtract numbers using the calculator. They investigate patterns in place value and explore relationships between numbers on the hundred chart.https://education.ti.com/en/activity/detail/amazeing-secret-paths
Action-Packed Subtraction Patterns
Students learn to use manipulatives and calculators to explore what happens when they change one number at a time in a subtraction number sentence. They record and develop the pattern that develops.https://education.ti.com/en/activity/detail/actionpacked-subtraction-patterns
Action-Packed Stories
Students learn to use whole numbers and the operations of addition and subtraction. They choose a number and create a story using the number selected and illustrate the number story. They represent the action in the story on the calculator.https://education.ti.com/en/activity/detail/actionpacked-stories
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
Randomization in Sampling and Experiments
This activity covers random sampling and randomization for experiments.https://education.ti.com/en/activity/detail/randomization-in-sampling-and-experiments
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
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 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
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
In this activity, you will construct the geometric object by following the instructions below, and then answer the questions about the object.https://education.ti.com/en/activity/detail/properties-of-parallelograms_4
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
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
Thrift Store Markdowns
Students will calculate a series of discounts using increasing unit fractions.https://education.ti.com/en/activity/detail/thrift-store-markdowns
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
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
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
What is an Exponent?
...at 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 sense of the computations: , , and in particular, allows students to investigate whether exponents “distribute” over operations other than mul...https://education.ti.com/en/activity/detail/what-is-an-exponent--bc
