Wk4 Q4 Online Learning Apr 20-24 Algebra 1

TeacherStephanie Durrance
Subject AreaAlgebra I Honors
Grade Level7th/8th
Week #4
Unit of InstructionUnit 10: Summary of Functions
Standard(s) Taught

MAFS.912.F-IF.3.9: Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions)

MAFS.912.F-IF.3.7b: Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated functions. Graph square root, cube root, and piecewise defined functions, including step functions and absolute value functions.

Learning Targets and Learning Criteria
  • Compare key features of two functions when represented in different ways (algebraically, graphically, numerically in tables, or by verbal descriptions)
  • define piecewise functions as functions that have different rules for evaluation depending on the value of the input
  • identify which evaluation rule to use for specific values of x
  • represent a piecewise function with a table or graph by evaluating several values of x
Classroom Activities

Monday/Tuesday:

Pre-work:

No live Zoom lessons. Please see the direct teaching resources below on graphing piecewise-defined functions.

Graph piecewise-defined functions (10 min): https://learnzillion.com/lesson_plans/5005-graph-piecewise-defined-functions/

How to graph a  piecewise function (10 min):  https://www.youtube.com/watch?v=n-EgnuaThpE

ISN (10 min): Watch both direct lessons above and take notes in ISN on new page titled “Piecewise-Defined Functions.”

Independent Work:

Khan Academy (20 min): Complete assigned video “Graphing piecewise functions” and assigned quiz “Piecewise functions graphs.”

Algebra Nation Online (20 min): Section 8, Topic 6: Understanding Piecewise-Defined Functions, Video and Check Your Understanding Quiz

Algebra Nation Workbook (20 min): Pages 211-212 Understanding Piecewise-Defined Functions

EOC Review Packet (10 min): Page 9 #1-3

 

Wednesday:

Graphing Technology Practice (45 min): Go to https://www.desmos.com/calculator to practice graphing on a free online graphing calculator tool. It is a great resource to help you with graphing any type of function. On the left side you will input what you want to graph. Practice graphing the following piecewise function. Type in box 1: f(x) = 2 {-1 < x < 4} Type in box 2: f(x) = 2x + 4 {x < -1} Type in box 3: f(x) = x – 1 {x > 4}. You will see the graphing tool graphed your piecewise function. Now, try to create your own piecewise function and let the tool graph it for you. The graphing tool is for practice only, but you are welcome to send a picture on remind or email of your creation!
