Statistical Plots
This activity gives students an opportunity to select and create the most appropriate graph to represent a given data set.https://education.ti.com/en/activity/detail/statistical-plots
We Have the Same Birthday
In this activity, students use simulations to answer a popular question involving probabilities. They will use the randInt and mean commands to determine the average number of people that need to be in a room to share a birthday.https://education.ti.com/en/activity/detail/we-have-the-same-birthday
Where Did the Parentheses Go
In this activity, students use the order of operations and number properties to create a unique expression from a set of numbers that must equal another number. Then, they will place parenthesis in a number statement to make it true. Students will also identify properties commonly used to evaluat...https://education.ti.com/en/activity/detail/where-did-the-parentheses-go
The Same Name Game
In this activity, students explore the meaning and purpose of equivalent fractions. They also practice writing fractions that meet a given criteria.https://education.ti.com/en/activity/detail/the-same-name-game
A Move in the Right Direction
Students physically provide motion data that is collected by a CBL™ and then graph the data. They determine if they "moved in the right directions" by comparing their graph with those printed in the activity.https://education.ti.com/en/activity/detail/a-move-in-the-right-direction
Are There Any Seats Left
This activity allows students to use a simulation to understand why airline companies routinely overbook flights.https://education.ti.com/en/activity/detail/are-there-any-seats-left
Got Complements? with Cabri Jr.
Use the Axes and Measure Angle tool to explore and calculate complementary angles.https://education.ti.com/en/activity/detail/got-complements--with-cabri-jr
Changing Before My Eyes
In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates.https://education.ti.com/en/activity/detail/changing-before-my-eyes
Calculating Unit Prices
In this activity, students will compare ratios with different denominators, and then with common denominators. They will also find unit rates.https://education.ti.com/en/activity/detail/calculating-unit-prices
Got an equilateral triangle? with Cabri Jr.
Using the Compass tool in Cabri Jr., students will construct an equilateral triangle, and check the length of each side. When a vertices is moved using the Alpha hand, the triangle remains equilateral.https://education.ti.com/en/activity/detail/got-an-equilateral-triangle---with-cabri-jr
Compound Interest
In this activity, students will calculate compound interest. They understand that in compound interest computations, the interest from the previous period is added to the current principal and the new total is used as the basis for calculating the interest.https://education.ti.com/en/activity/detail/compound-interest
Future Value of an Ordinary Annuity & Sinking Funds
In this activity, students carry out financial computations, involving annuity, and the future value of annuities. Students also deal with computations involving sinking funds.https://education.ti.com/en/activity/detail/future-value-of-an-ordinary-annuity--sinking-funds
Amortization Tables
In this activity, students carry out financial computations, involving amortization. Students will prepare amortization tables indicating principal payments, interest payments, and the balance on a loan for each time interval.https://education.ti.com/en/activity/detail/amortization-tables
Loans and Mortgages
In this activity, students perform financial computations, involving loans, their repayment and mortgages used as security for the repayment of a loan.https://education.ti.com/en/activity/detail/loans-and-mortgages
Congruent Triangles
Explore the results when a new triangle is created from an original triangle using the SSS, SAS, and ASA sets of conditions for congruence. In doing so, they will use the Cabri Jr. Compass tool to copy a segment and the Rotation tool to copy an angle.https://education.ti.com/en/activity/detail/congruent-triangles_3
Number Sets
When you start this activity, students receive a Venn diagram of real number sets (natural, whole, integer, rational, irrational)on their calculator. This same diagram is projected on the Activity Center screen at the front of the room. The teacher writes a value on the board and students move th...https://education.ti.com/en/activity/detail/number-sets
Shark Attack
Students use the Transformation Graphing application to separate what effect each change in the Point-Slope equation has on the graph.https://education.ti.com/en/activity/detail/shark-attack
Multiplication of Integers
Students use StudyCards(tm) to practice completing multiplication equations that include positive and negative integers.https://education.ti.com/en/activity/detail/multiplication-of-integers
