In this Khan Academy activity, students will determine if a point lies within, outside, or on a given circle.
Instruction and practice on all operations with polynomials.
Students will explore the connection between exponential growth and geometric sequences and to compare linear growth to exponential growth in context.
Students combine polynomial arithmetic with pattern-matching. Students can expand powers of x+1 using either repeated multiplication or by the binomial theorem, and then are asked to analyze the question of whether the similarity of coefficients with the digits of powers of 11 is a coincidence.
This tasks emphasizes the choice aspect of the full standard, giving students the option of several forms of a quadratic expression to choose from when answering questions about a real-world scenario governed by that expression. The task avoids having the students do the algebraic manipulations themselves, focusing instead on using the structure of the expressions.
This video proves why perpendicular lines have slopes that are negative reciprocals.

Quadratic practice interpreting word problems.
This video models a context that concerns a candy vending machine. The model turns out to be a quadratic inequality.
Interactive Desmos activity that explains how parabolas and quadratic equations are related.
This video solves a system of a quadratic equation and a linear equation by graphing both equations and looking for their intersections, and then checks the solution algebraically.
This video that solves a word problem about a ball being shot in the air. The equation for the height of the ball as a function of time is quadratic.
Printable worksheet with quadratic graphs and real world examples.
In this Khan Academy activity, students will be given a quadratic function from a word problem and be asked different questions about that model.
In this lesson, the concept of factoring quadratic equations to obtain the zeros/solutions through the proper formula is discussed.
