The goal of this lesson, Math Pixels, Points, Segments, and Lines is to clarify resolution and to introduce another method for creating digital art. With the use of vectors graphics and anchor points, students can create art that can be resized to any size, even mural size. Students will use the coordinate plane and their prior knowledge of equations to define these vector paths. Students will use domain to define the beginning and ending point (anchor points) for these vector graphics.

Note-In all parts of this lesson, students are working in groups. I suggest you make the best decision on assigning students to groups of 3-4. I personally use random selection and my class groups change after each project. This encourages students to get to know each other and work together with different learning styles.

Continually assess students as they progress through the lesson using questioning strategies.

California Math Common Core Standards (3) Show Standards

• A.CED.1 Create equations and inequalities in one variable including ones with absolute value and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.
• A.CED.2 Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
• G.GPE.1 Derive the equation of a circle of given center and radius using the Pythagorean Theorem; complete the square to find the center and radius of a circle given by an equation.

California Academic Content Standards (1) Show Standards

• M.8-12.AI.9.0 Students demonstrate and explain the effect that changing a coefficient has on the graph of quadratic functions; that is, students can determine how the graph of a parabola changes as a, b, and c vary in the equation y = a(x-b)²+c.

• Students will use equations to define paths and the domains of the equations to determine anchor points.
• Given a shape on the coordinate plane, students will give the equation matching that shape.
