Factoring Special Cases
Given a set of shapes whose combined areas represent the left-hand expression, students manipulate them to create rectangles whose areas are equal to the right-hand expression.https://education.ti.com/en/activity/detail/factoring-special-cases
Bewildered Babies
After making charts and using logic to list possible label arrangements, students compare their results with the output of the combinations formula and nCr command.https://education.ti.com/en/activity/detail/bewildered-babies
Closure Tables
Students create and complete closure tables to determine if the sets of whole numbers, integers, even numbers, and odd numbers are closed under the operations of addition, subtraction, multiplication, and division.https://education.ti.com/en/activity/detail/closure-tables_1
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
Depreciation
In this activity, students perform computations involving depreciation of assets. They will study methods such as Straight line depreciation, Sum of the digits method and Double declining balance depreciation.https://education.ti.com/en/activity/detail/depreciation
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
What's Your Combination
Students are first introduced to the counting principle and the factorial symbol. Then, they will calculate combinations and permutations using these formulas and the nCr, n!, and nPr commands on the graphing calculator.https://education.ti.com/en/activity/detail/whats-your-combination
Here’s Looking at Euclid
Students explore several ways to calculate the Greatest Common Divisor and Least Common Multiple, including using Euclid’s Algorithm.https://education.ti.com/en/activity/detail/heres-looking-at-euclid_1
Light at a Distance: Distance and Light Intensity
In this activity, students will use a light sensor to record the light intensity at various distances from a bulb. They will compare the data to an inverse square and a power law model.https://education.ti.com/en/activity/detail/light-at-a-distance-distance-and-light-intensity
Building curves
Students approach performing the basic operations on the polynomials from a graphical perspective. Given the graphs of two functions, they plot points that lie on the graph of the sum of the functions and draw conclusions about its behavior. Next, they calculate a regression to fit the points the...https://education.ti.com/en/activity/detail/building-curves
Geometric Sequences & Series
Students find common ratios of geometric sequences on a spreadsheet and create scatter plots of the sequences to see how each curve is related to the value of the common ratio and/or the sign of the first term of the sequence.https://education.ti.com/en/activity/detail/geometric-sequences--series_1
The Calcumites are Coming! - TI-83
Students model the growth of a population and compare ideal growth with a population whose growth is limited. They use technology to find exponential and logistic regression equations and use them to plot models.https://education.ti.com/en/activity/detail/the-calcumites-are-coming--ti83
