Number Crunching! Number Munching!
Students comprehend the order of operations and apply this understanding to simplify and evaluate expressions. They also learn to represent problems that involve variable quantities with expressions and use the calculator as a tool to solve problems.https://education.ti.com/en/activity/detail/number-crunching-number-munching
Magic Nines
Students compute multiples of 9, 99, 999, and so forth, search for patterns in the products, and write generalizations of those patterns.https://education.ti.com/en/activity/detail/magic-nines
What's So Special about 11?
Students will compute multiples of numbers in search of patterns. As a class, they'll discover patterns in multiples of 9; then they'll do the same with patterns in multiples of 11. They will then practice writing the rule for 11, both verbally and algebraically, to summarize the discovered pattern.https://education.ti.com/en/activity/detail/whats-so-special-about-11_1
What's Your Mileage?
Students use linear equations to model and solve real-world problems. Students also see the correlation between the graph of an equation and its calculated slope by plotting graphs by hand and then calculating slopes with the calculator and comparing.https://education.ti.com/en/activity/detail/whats-your-mileage
What Makes a Food Nutritional?
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-nutritional
Circle Around
Students compute the circumference and area of circles. They understand that the ratio of the circumference to the diameter is a value (3.14) called pi.https://education.ti.com/en/activity/detail/circle-around
How Hot Is It?
Students who are familiar with the two most common standards of measuring temperature learn how to reliably convert from degrees Celsius to degrees Fahrenheit. Students also see how order of operations is crucial in an equation, through discussion and data entry on the calculator.https://education.ti.com/en/activity/detail/how-hot-is-it
