Testing Claims About Proportions
Students find z-scores and critical values to test claims about proportions.https://education.ti.com/en/activity/detail/testing-claims-about-proportions
Chi-Squared Tests
In this activity, students will look at a problem situation that involves categorical data and will determine which is the appropriate chi-square test to use: the chi-squared goodness of fit or the chi-squared two-way test.https://education.ti.com/en/activity/detail/chisquare-distributions
Square it Up!
Students investigate the method of least squares by finding the residuals and the sum of the squares of the residuals.https://education.ti.com/en/activity/detail/square-it-up_1
Collecting Pens (Continued)
In this activity, students learn how to instruct the calculator to collect and organize the results from several trials of a simulation designed to find out how many boxes of cereals a customer would have to buy to collect all six color pens. Students enter a prewritten program, analyze the resul...https://education.ti.com/en/activity/detail/collecting-pens-continued
Collecting Pens
Students explore simulation strategies to solve real world problems involving probability and randomness. They use the Monte Carlo procedure to simulate the collecting of six different colored felt-tipped markers from boxes of Kellogg's cereals. They examine and analyze summary statistics and sta...https://education.ti.com/en/activity/detail/collecting-pens
Collecting Data
In this activity, students investigate how to use random numbers to collect samples and how to randomly assign subjects to experiments to collect data. They also use the CBL system to collect data in real time.https://education.ti.com/en/activity/detail/collecting-data
Is it Rare?
Students use the Poisson distribution to determine the probabilities for various numbers of hurricanes hitting the United States in a given year.https://education.ti.com/en/activity/detail/is-it-rare
Candy Pieces
Students use a chi-square test for goodness-of-fit to determine if there is a significant difference between the proportions they find in the sample, and the proportions they would expect if the manufacturer produced equal proportions of each color.https://education.ti.com/en/activity/detail/candy-pieces
Analyzing Variance (ANOVA)
Students analyze variances of various data samples.https://education.ti.com/en/activity/detail/analyzing-variance-anova
Finding the Maximum Product
In this activity, students use the CellSheet™ Application to organize data. They solve a problem of finding two positive integers equal to or greater than zero with a given sum and the maximum product.https://education.ti.com/en/activity/detail/finding-the-maximum-product
Math TODAY: Wing Tabs Save Fuel
Using the USA TODAY® Infograph, 'Wing Tabs Save Fuel,' ratios and proportions will be used to explore the concept of similarity between a drawing/model and the actual dimensions. The effects of dilation (size change) on an image and pre-image will also be explored. In addition, students will look...https://education.ti.com/en/activity/detail/math-today-wing-tabs-save-fuel
Isosceles Triangle
In this activity, students construct isosceles and equilateral triangles. They discover that if two sides of a triangle are congruent, then the angles opposite them are congruent. They understand that an equilateral triangle is also equiangular.https://education.ti.com/en/activity/detail/isosceles-triangle
Square Tables
In this activity, students will make a variety of squares using square tiles and the Table feature of the TI-84 Plus C Silver Edition™ to discover patterns and make predictions off those patterns.https://education.ti.com/en/activity/detail/square-tables
Dilations in the Plane (Transformations)
In this activity, students will explore the properties of dilations and the relationships between the original and image figures.https://education.ti.com/en/activity/detail/dilations-in-the-plane-transformations
Dilations in the Plane
In this activity, students will learn to use the Dilation tool on the Cabri™ Jr. application. They will also investigate the properties of dilations and the effects of dilations in the coordinate plane.https://education.ti.com/en/activity/detail/dilations-in-the-plane_1
NUMB3RS - Season 2 - "Soft Target" - Is This Seat Taken?
In "Soft Target," Alan is considering how to arrange people in seats at a wedding. Charlie points out that although there are many possibilities for seating arrangements, you reduce those possibilities if you decide who needs to sit next to whom.https://education.ti.com/en/activity/detail/numb3rs--season-2--soft-target--is-this-seat-taken
