Lesson 1
Categorizing Relationships: Is it a Function?
Learning Targets:
I can identify whether a representation (ordered pairs, tables, graphs, or mapping diagrams) is a function or not a function
I can explain in writing why a representation is or is not a function using the "one output per input" rule
Activity:
Use Desmos to explore graphs and tables.
Test graphs using the vertical line test, analyze ordered pairs, and work with mapping diagrams.
When you are finished, submit a Google Form explaining your thinking for each representation and receieve immediate feedback.
Lesson 2
Exploring Functions through Real-world Modeling
Learning Targets:
I can write a function rule in function notation using real-world data
I can graph a function and explain what a specific point on the graph means in context
Activity:
Use real-world datasets (e.g. cost vs. number of items or distance vs. time).
Using GeoGebra, create a function rule, graph the relationship, and explore how changing the input affects the output.
Write a short paragraph explaining what your function means in real life, then compare your model with a partner's.
Lesson 3
Presentation of Functions in Multimodal Forms
Learning Targets:
I can create a digital portfolio that shows my understanding of a real-world function using algebra, graphs, and written explanation
I can present my work clearly and use feedback from my teacher and peers to reflect on my learning
Activity:
Create a digital presentation or infographic about a real-world function of your choice. Your portfolio needs to include an equation, a graph, and a written explanation. You will then give a short presentation to the class and receive feedback from both the teacher and your classmates.
