Students take a field trip to a local ski area(or simply a nearby hill) and calculate the slope of a hill at several positions.https://education.ti.com/en/activity/detail/exploring-slope-slope-on-the-slopes
Trigonometric Ratios
Students discover the trigonometric ratios through measuring the side lengths of similar triangles and calculating their ratios. The formal definitions of the sine, cosine, and tangent or an angle are presented and applied to find the missing side lengths.https://education.ti.com/en/activity/detail/trigonometric-ratios
Investigating the Pythagorean Theorem
Use your TI-84 Silver Plus calculator and the Carbri Jr file 'PYTHAG' to have students investigate what happens to the results of the Pythagorean Theorem for acute, right, and obtuse triangles.https://education.ti.com/en/activity/detail/investigating-the-pythagorean-theorem
Linear Equations Jeopardy
This activity is designed as a review of linear equations. Students will review slope, functions, writing equations in slope-intercept form, and point-slope form.https://education.ti.com/en/activity/detail/linear-equations-jeopardy
Tides of Yaquina Bay
Students will use real data to determine average low and high tideshttps://education.ti.com/en/activity/detail/tides-of-yaquina-bay
Linear Functions using the CBL 2™
Students will generate data on the CBL 2™ to represent a linear function. They will investigate the slope of a direct variation. Then they will use different starting points to represent y intercept.https://education.ti.com/en/activity/detail/linear-functions-using-the-cbl-2
Linear Regression: Wing Span/Height
Students take measurements of individual's wing span and height and create a coordinate graph. The activity should include at least three different grade levels. Students submit an equation through "Activity Center" and the class compares the different equations.https://education.ti.com/en/activity/detail/linear-regression-wing-spanheight
Going Into Business
Students will work through a scenario of a business venture involving washing dogs.https://education.ti.com/en/activity/detail/going-into-business
Stretching the Quads
Students stretch and translate the parabola given by y = x2 and determine the effects on the equation.https://education.ti.com/en/activity/detail/stretching-the-quads
Hot Wheel Lab
In this activity, students will gather data that compares the slope of a hot wheel ramp to the distance the car travels. They will then graph, draw a line of best fit and write an equation for their data.https://education.ti.com/en/activity/detail/hot-wheel-lab
Arithmetic Sequences & Series
Students use formulas to find the differences of the consecutive terms, plot a scatter plot of each sequence, and determine that sequences with common differences (called arithmetic sequences) have scatter plots whose points form a straight line.https://education.ti.com/en/activity/detail/arithmetic-sequences--series_1
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
Surface Area of a Cylinder
Students define right and oblique three dimensional figures and calculate the volume for prisms, pyramids, cylinders, and cones.https://education.ti.com/en/activity/detail/surface-area-of-a-cylinder
Tessellations
Students will explore tessellations of triangles and quadrilaterals. They will use the transformation tools of symmetry, reflections, rotations, and/or translations.https://education.ti.com/en/activity/detail/tessellations
Translations in the Coordinate Plane
It is important for students to know what happens to the coordinates of points when they are translated in the coordinate plane. This activity enables students to use Cabri Jr. to develop this understanding.https://education.ti.com/en/activity/detail/translations-in-the-coordinate-plane
Transformations With Lists
Students use list operations to perform reflections, rotations, translations and dilations on a figure, and graph the resulting image using a scatter plot.https://education.ti.com/en/activity/detail/transformations-with-lists
Triangle Sides & Angles
Students will explore side and angle relationships in a triangle. First, students will discover where the longest (and shortest) side is located relative to the largest (and smallest) angle. Then, students will explore the Isosceles Triangle Theorem and its converse. Finally, students will determ...https://education.ti.com/en/activity/detail/triangle-sides--angles_1
Law of Large Numbers: A Weighty Decision
In this activity, students will explore the Law of Large Numbers. By examining unfair models, they will expand their understanding of probability. They predict the weighting of an unfair model by analyzing experimental data and distributions. They will also formulate and test a hypothesis on the ...https://education.ti.com/en/activity/detail/law-of-large-numbers-a-weighty-decision
Off to the Races
In this activity, students set weights for factors and observe how it affects the probability of a particular outcome. They set a weight for 3 factors for each of the six horses in a race. The three factors are weighted differently in different parts of the race. They compare the experimental and...https://education.ti.com/en/activity/detail/off-to-the-races
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
NUMB3RS - Season 3 - "Waste Not" - Different or Not?
In the episode, the FBI discovers that children in the area of a sinkhole seem to have an unusually high occurrence of cancer. FBI agent Megan Reeves believes that this might represent a "cancer cluster," but Charlie warns her not to jump to this conclusion too quickly. Students will use a statis...https://education.ti.com/en/activity/detail/numb3rs--season-3--waste-not--different-or-not
Perpendicular Bisector of a Line Segment
Students learn to draw a segment and its perpendicular bisector. They understand right angles and congruent segments. Students observe that changing the length or orientation of the segment changes the perpendicular bisector. NCTM Geometry Standard covered: Analyze characteristics and properties ...https://education.ti.com/en/activity/detail/perpendicular-bisector-of-a-line-segment
Perpendicular Segments in a Circle
Students learn about chords of a circle. They draw a line perpendicular to the chord and passing through the center of the circle. They explore the lengths of the two segments of the chord. They investigate with a different chord and with different sized circles. NCTM Geometry Standard covered: A...https://education.ti.com/en/activity/detail/perpendicular-segments-in-a-circle
