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
Exploring the Unit Circle
In this activity, students explore the properties of a unit circle and its mapping functions.https://education.ti.com/en/activity/detail/exploring-the-unit-circle
Cottage Water Problem
Students use the Cabri Geometry II Plus software to solve a geometry problem. They move the vertex point that is common to two right triangles along the base to find the smallest possible sum of the length of the hypotenuse.https://education.ti.com/en/activity/detail/cottage-water-problem
Pizza Extravaganza
Students will conduct a survey of the class to determine favorite pizza toppings. They use this sample information to predict the preferred toppings for the school and use the TI-15 to help them with the calculations to plan a school-wide pizza party.https://education.ti.com/en/activity/detail/pizza-extravaganza
Making Cookies
Students will reduce a cafeteria recipe to suit a household recipe. They use compatible numbers to choose smaller measurements while retaining the original proportions.https://education.ti.com/en/activity/detail/making-cookies
Number of Regions - An Introduction to the TI-Nspire CAS
