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
Graphs and Fractions
Have students draw squares on graph paper and half some of the squares on the outside. Number all the squares and continue numbering with the halfs. Students are then instructed to create their own ratios such as: 4 halves to eight wholes of odd numbers etc. Encourage student's to be creative by ...https://education.ti.com/en/activity/detail/graphs-and-fractions
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
Surface Area of Cylinder Song
Here's a silly song that I use with my classes to help them remember how to find the surface area of cylinders. My students actually suggested that I submit this!https://education.ti.com/en/activity/detail/surface-area-of-cylinder-song
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
Quilt Blocks
Students will see how fractions, decimals, and percents are interrelated, then explore and learn how to convert between them. Students will also practice estimating.https://education.ti.com/en/activity/detail/quilt-blocks
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 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
Pizza Extravaganza
Students will conduct a survey of the class to determine favorite pizza toppings.

What's Half of a Half of a Half?
Students will use a physical model to determine what happens when they repeatedly halve a piece of paper, and then they reassemble the pieces into a whole. They then use an algebraic model to analyze the same situation, which leads to an introductory discussion of limits.https://education.ti.com/en/activity/detail/whats-half-of-a-half-of-a-half_1
