# Q4W28 Algebra Teacher Carol Barnes Algebra 7th/8th Q4W28 March 21-25 Polynomials & Quadratics
Standard(s) Taught
Learning Targets and Learning Criteria
• factor quadratic expressions and functions

• divide polynomials

• factor polynomials with four terms

• apply models for factoring and multiplying polynomials to rewrite expressions and functions

•
• write a function to model a real-world context by composing functions and the information within the context.

• explain process of composition – that is, explain that f(g(x)) takes an x value to its g output and then takes the g output to its f output.

• divide polynomials using long division and apply the Remainder Theorem, when appropriate, to check the answer. (next week)

• write a function that combines functions using arithmetic operations (addition, subtraction, and multiplication) and relate the result to the context of the problem.

• interpret individual parts of a quadratic expression

Classroom Activities

Monday/Tuesday:

Whole Group:  Print and take notes on Factoring Polynomials with four terms with this page:  Factoring Polynomials with four terms.   From home, watch the video of teacher going over the notes at this link: https://www.youtube.com/watch?v=xJGtPJL4KDM.

Independent Work:  For a grade: HW9 Factoring 4 Term Polynomials .

Whole Group:  Print and take notes on Factoring Polynomials with Division (show remainder theorem) with this page: Dividing Polynomials by Binomial .   From home, watch the video of teacher going over the notes at this link: https://youtu.be/_ylUlFA-dxw   https://youtu.be/_ylUlFA-dxw

Independent Work:  HW12 Dividing Polynomials

Wednesday:

Whole group:  Students watch Polynomial Remainder Theorem Video which shows how to divide polynomials with long division at this link:       https://www.khanacademy.org/math/algebra2/x2ec2f6f830c9fb89:poly-div/x2ec2f6f830c9fb89:remainder-theorem/v/polynomial-remainder-theorem

Independent: Students will work problem on Khan Academy after video.

Thursday/Friday:  This lesson has been moved to next week.

Notes on Introduction to Quadratic Functions:

Whole Group:  Students create flip book on Quadratic Functions to use Interactive Student Notebook.  Here is link to Flip Book: Quadratic Functions Intro FlipBook then create foldable showing transformations of quadratic functions using vertex form using this link to print foldable: Transformations QuadraticFunctionsVertexFormFoldable-2

Independent:  Complete graphs showing major features of parabolas from quadratic equations in All Things Algebra.
