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
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
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
So Many Zeros!
Students will explore standard and scientific notation representations of numbers. Students will also discuss the need for different representations of very large or small numbers, and they will see real-world examples of these representations.https://education.ti.com/en/activity/detail/so-many-zeros
Creating Word Problems
Students write word problems based on the whole numbers generated by the calculator. They decide on an operation to solve the problems. Finally, they analyze the problems to determine the problem characteristics when using operations on whole numbers.https://education.ti.com/en/activity/detail/creating-word-problems
What's the Fastest Way to Get Rich?
Students investigate exponential growth and discover patterns by exploring different scenarios involving money. They will learn how repeatedly doubling, or multiplying by two, can also be expressed exponentially.https://education.ti.com/en/activity/detail/whats-the-fastest-way-to-get-rich
In Round Numbers
Students will develop and test rules for rounding whole numbers and decimal fractions. They will use the information to solve real-world problems.https://education.ti.com/en/activity/detail/in-round-numbers
Absolute Values
Students will review the set of integers along with the addition and subtraction of integers using a number line. Then, they will learn that the absolute value of a number is defined as the distance from zero. Students will learn how to interpret the absolute value symbol algebraically, as well a...https://education.ti.com/en/activity/detail/absolute-values
