Students will use the converse of the Pythagorean Theorem to predict a triangle's classification. The Cabri Jr. App on the TI-83+/84+ family will be used to create triangles and find their measurements.https://education.ti.com/en/activity/detail/the-pythagorean-theorem-and-classifying-triangles
Triangle Inequalities
This activity will help students visualize the properties of triangles stated in the theorems. By dragging the vertices, the students can see that the properties hold regardless of the size of the triangles and which sides are the longest or shortest.https://education.ti.com/en/activity/detail/triangle-inequalities_2
REAL LIFE REAL WORLD - Avalanche Rescue
When hikers and skiers go into terrain with a risk of avalanches, they take safety equipment including avalanche rescue beacons. An avalanche rescue beacon sends and receives electromagnetic field signals that travel in circular patterns. The search pattern used to locate a beacon buried in the...https://education.ti.com/en/activity/detail/real-life-real-world--avalanche-rescue
The Spread of Disease
In this activity, students simulate the spread of a disease in a population. They use the Probability Simulation application to learn that certain sums occur more often than others because of combinations of addends of those sums.https://education.ti.com/en/activity/detail/the-spread-of-disease
t Distributions
Students compare the t distribution to the standard normal distribution and use the invT command to find critical values for a t distribution.https://education.ti.com/en/activity/detail/t-distributions
Organized Guess and Check using CellSheet
Students will use the APP CellSheet to aid in answering a typical guess and test problem. The activity will help in their organizational ability as well as with cell sheet usage. Their answers will be shared using Navigatorhttps://education.ti.com/en/activity/detail/organized-guess-and-check-using-cellsheet
The Golden Ratio
The students will engage in a hands on activity to determine how they fit into the golden ratio which is considered the mathematically perfect ratio. Is it necessary or important to relate to this number?https://education.ti.com/en/activity/detail/the-golden-ratio
Incenter of a Triangle
In this activity, students observe a special characteristic of the bisectors of the angles in a triangle. They test their conjecture by changing the size and shape of the triangle. NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes and ...https://education.ti.com/en/activity/detail/incenter-of-a-triangle
Constructing Quadrilaterals
In this activity, students will construct different types of quadrilaterals from the quadrilateral hierarchy. This activity asks for constructions based on a minimal definition of the quadrilateral. The activity will reinforce the difference between a construction and a drawing.https://education.ti.com/en/activity/detail/constructing-quadrilaterals
Perpendicular Slopes
Students investigate the "negative reciprocal" relationship between the slopes of perpendicular lines. The final phase of the activity is appropriate for more advanced students as they are led through an algebraic proof of the relationship.https://education.ti.com/en/activity/detail/perpendicular-slopes_1
Simulating Coin Toss Probability
Students will understand patterns, relations, and functions.https://education.ti.com/en/activity/detail/simulating-coin-toss-probability
Saving for Graduation
In this activity, students use the CellSheet™ Application to calculate accrued interest on a principal. During the activity students solve a problem to calculate the interest on a principal, for a specified period.https://education.ti.com/en/activity/detail/saving-for-graduation
Grandparents and Special Friends Day
This lesson was designed for our Grandparents and Special Friends day. It can be used for any visitation day, or an open house. The lesson is designed to review percent of a whole and the sector of the circle representing the percentage. Although circle graphs can be created in a spreadsheet prog...https://education.ti.com/en/activity/detail/grandparents-and-special-friends-day
You're So Dense - TI-83
Students investigate the relationship between density of an object, its mass and its volume. They use mass and volume measurements to determine the density of pennies. They compare the density of pre-1983 and post-1984 pennies.https://education.ti.com/en/activity/detail/youre-so-dense--ti83
Social Security Issues
In this activity, you will look at the relationship between the age at which you start drawing social security and the amount drawn. Both graphs and spreadsheets will be used.https://education.ti.com/en/activity/detail/social-security-issues
Guess the Ages
In this activity, the teacher will pick favorite "famous" people and ask the students to guess their ages. The names and birth dates are attached ("Famous Persons Birth Dates"). Participants use the calculator to enter the information and to view results.https://education.ti.com/en/activity/detail/guess-the-ages
