Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.

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.

Locating a point on a grid is an important skill to master; use this practice sheet to give schlars some clear and useful experience. On a large, simple grid they use a coordinate system to find specific squares and color them a given...

As you introduce graphs and coordinate pairs, use this guided activity to get scholars started. They reference an example before recording number pairs to identify the location of 12 letters on a grid. Next, learners examine shapes on a...

Before learning about the coordinate plane and ordered pairs, have kids get used finding locations on the grid. They are given a simple set of coordinates, which they will locate on the grid. A great way to introduce the concept. 

High schoolers participate in a role-play activity to determine how to replace heat shields on the space shuttle using polar coordinates.

Build right angles using coordinate geometry! Pupils explore the concept of slope related to perpendicular lines by examining 90-degree rotations of right triangles. Learners determine the slope of the hypotenuse becomes the opposite...

Where in the world (or at least in the coordinate plane) is the third vertex? Given two coordinate points for the vertices of a triangle, individuals find the location of the third vertex. They read an account of fictional...

Working independently or in teams, your class practices connecting graphs, formulas and words. This lesson includes a guided discussion about distance vs. time graphs and looking at how velocity changes over time.  

Explore the concept of, and use the Ti-Nspire to, convert complex numbers into polar form. Then practice graphing complex numbers in the polar coordinate plane.

How do you build a polygon from an inequality? An engaging lesson challenges pupils to do just that. Building from the previous lesson in this series, learners write systems of inequalities to model rectangles, triangles, and even...

A geometry module connects algebraic reasoning to geometry. It challenges scholars to investigate the slope criteria for parallel and perpendicular lines, prove theorems involving coordinate geometry, and write equations for circles and...
