Q1 W9 Oct 26-Oct 30 Algebra 1

Teacher Stephanie Durrance Algebra 1 Honors 7th/8th 9 Unit 3 - Introduction to Functions
Standard(s) Taught

MAFS.912.A-APR.2.3: Identify zeroes of polynomials when suitable factorizations are available, and use the zeroes to construct a rough graph of the function defined by the polynomial.

MAFS. 912.F-IF.2.4: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship

Learning Targets and Learning Criteria

• identify zeros from a graph of a polynomial.
• identify zeros of factored polynomials.
• identify the multiplicity of the zeroes of a factored polynomial.
• explain how the multiplicity of the zeroes provides a clue as to how the graph will behave when it approaches and leaves the x-intercept.
• sketch a rough graph using the zeroes of a polynomial and other easily identifiable features such as the y-intercept and the end behavior.
• find the key features of the graphs and tables of a function (x and y intercepts, maximums, minimums, increasing and decreasing intervals, end behavior)

Classroom Activities

Innovative Students – Log into Zoom on time and begin working on bellringer. Be prepared to follow the schedule of activities below.

Whole Group:
Discuss summative assignment “Creating a Rollercoaster”
Independent:
Students will create their own rollercoaster on graph paper. Then, they will name their rollercoaster and identify parts of their graph, such as the zeros, y-intercept, maximum, minimum, one increasing interval, one decreasing interval, a possible equation, and end behavior.

All IEP and ESOL accommodations provided daily.
