Solution 12157: Setting the Default Units for Displayed Results on the TI-89 Family, TI-92 Family and Voyage™ 200 Graphing Calculators.
... Many categories let users select NONE as the default unit. This means that the result in that category will be displayed in the default units of its components. For example, Area= (Length)^2, so Length is a component of Area. If the defaults for Area is _acre and for Length is _m, area results w...https://education.ti.com/en/customer-support/knowledge-base/other-graphing/product-usage/12157

...nected. The samples are taken and stored in the CBL 2 memory until all the data have been collected. The data can be sent to the calculator after the completion of the data collection. The quantity of data collected is not limited by the size of the calculator memory, but is limited by the size o...https://education.ti.com/en/customer-support/knowledge-base/data-collection-accessories/product-usage/16509
Solution 12156: Scaling the X-axis and Y-axis with the Same Units on TI-89 Family, the TI-92 Family, and the Voyage™ 200.
... when graphing a function on TI-89 family, the TI-92 family, and the Voyage 200? To make the scale on the x-axis and y-axis the same, use the ZoomSqr command. The ZoomSqr command displays the graph screen, adjusts the x or y window settings so that each pixel represents an equal width and height ...https://education.ti.com/en/customer-support/knowledge-base/other-graphing/product-usage/12156

Heat Transfer by Conduction
The purpose of this activity is to monitor the transfer of heat between 2 materials by measuring the temperature changes in them.https://education.ti.com/en/activity/detail/heat-transfer-by-conduction
Exploring Hurricane Strength
In the activity, we explore multiple regression equations among Saffir-Simpson Scale, Pressure, Wind Speed, and Storm Surge of hurricanes. We relate our models to Hurricane Katrina, Gustav, and Ike.https://education.ti.com/en/activity/detail/exploring-hurricane-strength
Median and Interquartile Range
In this lesson students are introduced to the median and, by taking the median of each half of the data, to quartiles and the interquartile rangehttps://education.ti.com/en/activity/detail/medians-and-iqrs-bc
Mean As a Fair Share
This lesson introduces students to mean as a way to describe the center of a set of data. Often called the average, the mean can also be visualized as “leveling out” the data in the sense of “fair share”.https://education.ti.com/en/activity/detail/mean-as-a-fair-share-bc
Mean As A Balance Point
In this lesson, students calculate deviations from the mean, how far each value is above or below the mean. Students also focus on the balance point of a distribution, where the sum of the absolute deviations below the mean is equal to the sum of the absolute deviations above the mean.https://education.ti.com/en/activity/detail/mean-as-a-balance-point-bc
Box Plots
In this lesson, students plot the two extreme values (minimum and maximum), the lower quartile (LQ), upper quartile (UQ), and the median (a five-number summary) on a number line to create a graph called is a box plot.https://education.ti.com/en/activity/detail/box-plots-bc
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
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
Equations and Operations
In this lesson students investigate the relationship between the solution to an equation and the solution to a new equation formed by adding, subtracting, multiplying, or dividing one or both sides of the original equation by a numerical value. Students develop an understanding of “solution...https://education.ti.com/en/activity/detail/equations-and-operations-bc
