NUMB3RS - Season 3 - "Killer Chat" - The Perfect House
The FBI found three bodies in different unoccupied houses, all for sale. Because the victims are completely unrelated, Charlie decides that profiling the houses might reveal a distinct pattern to find out where the killer will strike next. By using a Multi-Attribute Compositional Model, the house...https://education.ti.com/en/activity/detail/numb3rs--season-3--killer-chat--the-perfect-house

Transient Circuit Analysis: Numeric
Describes how the differential equation plotter is used to solve the second-order circuit presented in Chapter 2 (Topic 8) by expressing it as a system of first-order differential equations.https://education.ti.com/en/activity/detail/transient-circuit-analysis--numeric
Cereal Numbers
Students build numbers from zero to ten with cereal and connect the number name and numeral. Students also explore number sentences for numbers up to ten.https://education.ti.com/en/activity/detail/cereal-numbers
Area Patterns
Students investigate patterns in ordered pairs generated by constructing a sequence of similar shapes. They will then use the patterns and the calculator to predict the number of blocks it will take to build a specific shape in the sequence.https://education.ti.com/en/activity/detail/area-patterns
Analyzing Number Cube Sums
Students extend their understanding of theoretical probability and patterns. They use number cubes, to build awareness that a fraction and its decimal and percent representation on the calculator are "close," but not necessarily equal.https://education.ti.com/en/activity/detail/analyzing-number-cube-sums
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
Measurement and Geometry
Students explore the use of manipulatives to conduct simple geometry and measurement activities.https://education.ti.com/en/activity/detail/measurement-and-geometry
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
Map It!
Students explore map making. Students read a story, identify the locations of different places in the story, decide the distance between each set of places in the story, and create a map with a legend.https://education.ti.com/en/activity/detail/map-it
Making Picture Graphs
Students learn to make picture graphs with symbols that represent more than one piece of data.https://education.ti.com/en/activity/detail/making-picture-graphs
Laplace Analysis: The s-domain
Demonstrates the utility of symbolic algebra by using the Laplace transform to solve a second-order circuit. The method requires that the circuit be converted from the time-domain to the s-domain and then solved for V(s). The voltage, v(t), of a sourceless, parallel, RLC circuit with initial co...https://education.ti.com/en/activity/detail/laplace-analysis--the-sdomain
How Salty Is It?
Students learn to solve a real-world problem involving salt water. Students will determine the amount of sea salt needed to turn an aquarium into a simulated salt-water environment. They also experiment with items and check their buoyancy in water with varying salt concentrations.https://education.ti.com/en/activity/detail/how-salty-is-it
Hat Trick
Students learn to solve a real-world problem in economics. Students get to understand how surveys often use a sample of people rather than all of the people involved. They also learn how to make decisions based on the results of a sample survey.https://education.ti.com/en/activity/detail/hat-trick
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 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
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
