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
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
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
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
What's the Trig?
Students will be introduced to right triangle trigonometry. They will use the TI-89 and Geometer's Sketchpad to construct a right triangle and calculate sin, cosine, and tangent of various acute angles. (Topic - Right Triangle Trigonometry)https://education.ti.com/en/activity/detail/whats-the-trig
Surface Area of Cylinder Song
Here's a silly song that I use with my classes to help them remember how to find the surface area of cylinders. My students actually suggested that I submit this!https://education.ti.com/en/activity/detail/surface-area-of-cylinder-song
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
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
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
Quilt Blocks
Students will see how fractions, decimals, and percents are interrelated, then explore and learn how to convert between them. Students will also practice estimating.https://education.ti.com/en/activity/detail/quilt-blocks
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
What Makes a Food Nutritious?
Students will analyze select nutritional values of specific food products and then compare those values to the recommended daily allowances published by the U.S.D.A. They will calculate percentages and fractions based upon the information they find.https://education.ti.com/en/activity/detail/what-makes-a-food-nutritious
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
What's Half of a Half of a Half?
Students will use a physical model to determine what happens when they repeatedly halve a piece of paper, and then they reassemble the pieces into a whole. They then use an algebraic model to analyze the same situation, which leads to an introductory discussion of limits.https://education.ti.com/en/activity/detail/whats-half-of-a-half-of-a-half_1
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
