Electromagnetics
Describes how to use the TI-89 to solve Laplace's equation for two-dimensional electrostatic problems. The separation of variables method provides exact solutions but is restricted to specific geometries. The relaxation method is applicable to any geometry, but it provides only an approximate s...https://education.ti.com/en/activity/detail/electromagnetics
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
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
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
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
The Normal Distribution
Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.https://education.ti.com/en/activity/detail/the-normal-distribution_1
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
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
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
Stepping Stones
Students use volume formulas and proportional reasoning to calculate the amount of concrete needed to make stepping stones of a specific size.https://education.ti.com/en/activity/detail/stepping-stones
