Building a Garden Fence
In this activity, students will use basic concepts of perimeter and area to investigate a classic problem situation requiring maximization. They must decide how to build a garden fence to enclose the largest possible area.https://education.ti.com/en/activity/detail/building-a-garden-fence
Cell Phone Range
Students will learn to identify the domain and range of various real-world step functions. They will graphically explore numerical data points and observe step functions.https://education.ti.com/en/activity/detail/cell-phone-range
Testing for Truth
Students identify whether points lie within a shaded region that is bounded by linear inequalities.https://education.ti.com/en/activity/detail/testing-for-truth
Data Collection for Bar Graphs
Students collect data outside of the classroom, organize their information into a bar graph within their groups, and then contribute their data to Navigator in the form of 2 lists to view and discuss as a classhttps://education.ti.com/en/activity/detail/data-collection-for-bar-graphs
Multiplying and Dividing Monomials
Students should know how to multiply and divide monomials.https://education.ti.com/en/activity/detail/multiplying-and-dividing-monomials
Ain't No River Wide Enough
Students simulate the process a surveyor would use to measure the width of a river by measuring length on one side of the river and angles formed by various reference points.https://education.ti.com/en/activity/detail/aint-no-river-wide-enough
Trig Ratios - IB
In this activity, students will use Cabri™ Jr. to discover the relationship between the trigonometric functions: sine, cosine and tangent and the side length ratios of a right triangle.https://education.ti.com/en/activity/detail/trig-ratios
ASA Triangle Congruence
1.Construct an triangle and select two angles and the contained side to copy to a second triangle. 2.Measure sides and angles to visualize congruence properties 3.Try to alter the properties of their construction by moving the vertices of the original trianglehttps://education.ti.com/en/activity/detail/asa-triangle-congruence

Solving Equations with Solve It
This activity will provide an opportunity for students to review solving equations on an application and still get credit for it.https://education.ti.com/en/activity/detail/solving-equations-with-solve-it
Midsegments of Triangles
Students explore the properties of the midsegment, a segment that connects the midpoints of two sides of a triangle.https://education.ti.com/en/activity/detail/midsegments-of-triangles
Midpoints in the Coordinate Plane
Beginning with horizontal or vertical segments, students show the coordinates of the endpoints and make a conjecture about the coordinates of the midpoint.https://education.ti.com/en/activity/detail/midpoints-in-the-coordinate-plane_1
Inference for Correlation and Regression
In this activity, students test if a significant relationship exists between a bivariate data set, and then calculate the confidence and predictive intervals.

NUMB3RS - Season 3 - "Waste Not" - Sharpshooter
It is believed that an unusually high occurrence of cancer in a small area may represent a "cancer cluster." Because this is rare, it is more likely to be a case of "Texas Sharpshooting." For example, suppose a person randomly shoots a gun several times at the side of a barn and draws a circle ar...https://education.ti.com/en/activity/detail/numb3rs--season-3--waste-not--sharpshooter
