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
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
Comparing Distributions of Univariate Data
Students compare univariate data distributions using statistical concepts like boxplots, stemplots, and histograms.https://education.ti.com/en/activity/detail/comparing-distributions-of-univariate-data
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 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
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
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
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
Set Design
Students will use similarity concepts, and the dimensions of the carvings on Mt. Rushmore to create a proportional representation of the carvings for a stage backdrop.https://education.ti.com/en/activity/detail/set-design
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
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
Number and Operation Sense: Rational Numbers
Students learn to use the calculator to collect a set of data in order to identify patterns that illustrate important rational number concepts: the relationship between rational numbers and division, and equivalent fraction and decimal forms for rational numbers.https://education.ti.com/en/activity/detail/number-and-operation-sense-rational-numbers
What Makes a Food Nutritious?
Students will analyze select nutritional values of specific food products and then compare those values to the recommended daily allowances published by the U.S.D.A. They will calculate percentages and fractions based upon the information they find.https://education.ti.com/en/activity/detail/what-makes-a-food-nutritious
Thrift Store Markdowns
Students will calculate a series of discounts using increasing unit fractions.https://education.ti.com/en/activity/detail/thrift-store-markdowns
Looks Right
Students use the Cabri Geometry II Plus software to determine which given triangle retains its basic shape after its vertices are dragged around the screen.https://education.ti.com/en/activity/detail/looks-right
Area of Triangle
