Constructing Lines from Individual Points in the Activity Center
Students will understand that a line is made up of many points that all follow the same rule.https://education.ti.com/en/activity/detail/constructing-lines-from-individual-points-in-the-activity-center
Binomial Multiplication
Students will enter an expression showing the multiplication of two binomials into Y1 in an equation that can be graphed. They will also multiply the binomials and enter the result into Y2 to verify that the graph remains the same. Finally, they will combine like terms and enter the result into...https://education.ti.com/en/activity/detail/binomial-multiplication
Breaking Spaghetti
Students will do a lab where they keep track of the number of strands of spaghetti versus how many "weights" it takes to break the spaghetti. They will enter lists and create a scatter plot. Students will also find the equation for the line of best fit. The TI-Navigator System can then be used...https://education.ti.com/en/activity/detail/breaking-spaghetti
Continuous Compounding
In this activity, students deal with financial computations, where the interest is compounded continuously. Depending on the length of each compounding period, students will determine the number of compounding periods.https://education.ti.com/en/activity/detail/continuous-compounding
Trains in Motion
Students will make observations about the motion of two objects. They will compare and contrast this motion and consider how it corresponds to a graph representing distance as a function of time.https://education.ti.com/en/activity/detail/trains-in-motion
Complex Numbers
Students calculate problems to determine the rules for adding, subtracting, multiplying, and dividing complex numbers.https://education.ti.com/en/activity/detail/complex-numbers
