Students measure scale drawings of famous "supertall" skyscrapers and solve more proportions to find the heights of other skyscrapers drawn with the same scale.https://education.ti.com/en/activity/detail/supertall-skyscrapers_1
Solving Equations by Graphing
This activity uses screen capture to introduce solving linear equations by graphing. Using screen captures save the teacher from having to go from one student to another to make sure the students' are typing the correct information into the calculator.https://education.ti.com/en/activity/detail/solving-equations-by-graphing
Greatest Area Activity
In this activity students will explore area as it compares to length of rectangles with a fixed perimeter by creating lists of the possible dimensions and the areas of these rectangles. Students will then graph a scatterplot of the data, find the quadratic regression, and explore the table of val...https://education.ti.com/en/activity/detail/greatest-area-activity_1
The Shrinking Dollar
Students examine the long term effects of inflation. They compute the increase in cost price due to compounding of inflation rates every year. They recognize that this increase in cost price is exponential.https://education.ti.com/en/activity/detail/the-shrinking-dollar
Maximum, minimum, increasing, decreasing
