Vectors
Young mathematicians connect vectors to geometric shapes by watching a video that expresses vectors in relation to the sides of geometric figures. They then apply what they learned by completing a activity of practice questions.

NUMB3RS Activity: Where’s the Source? Episode: “Undercurrents”
Several real-world problems are posed as a way to learn about vector fields in order to make some predictions after analyzing the data. The main problem comes from the tv show NUMB3RS and is based on solving a crime where a body has...

Visualizing Vectors
Investigate vectors in standard positions and use the CellSheet application on the TI calculator to find the sum of two vectors. Convert from polar to rectangular coordinates and vice versa, and show graphs of the vectors.

NUMB3RS Activity: Narrowing the Search
Young scholars explore the length of an n-dimensional vector. In this Algebra II/Pre-calculus instructional activity, students investigate an expansion of the Pythagorean Theorem to n-dimensional space.

Angling for Distance
Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile. Students launch baseballs on a football field and video tape the path of the ball.
