Reflection: Writing Across the Disciplines Running and the Domain of Middle Earth: Modeling a Run and a Hobbit's Journey through Piece-wise Functions - Section 3: Class Activity: Writing about Piece-Wise Functions

 

When reflecting on the piece wise lesson, I couldn't help but think about how the writing prompts helped students learn more about linear functions and also let me have a better understanding of student mastery of different concepts. 

For example, in Student Sample 1 Writing About Linear Functions the students has an emerging understanding of aspects of linear functions. This student is also looking for repeated reasoning and structure in equations to identify a function as linear (that function fits slope intercept form) which is great to see. 

Student Sample 2 Writing About Linear Functions tells me that this student understands what a linear function is, has a good conceptual understanding of slope and is thinking about how different representations of functions fit and talk to each other.

For Student Sample 3 Writing About Linear Functions, what I love about this sample is the student is making connections between the function and the context of the situation. When the student writes that a slope of zero means Jim is resting(not moving) it indicates that the student has a good understanding of the lesson concepts because the student is applying the information to an everyday situation.

All in all I was pleased with how this lesson played out in the classroom. All three of the samples from my fundamentals of Algebra class show examples of how all students can effectively access the Common Core math standards and how we can strive for continuous improvement.

Running and the Domain of Middle Earth: Modeling a Run and a Hobbit's Journey through Piece-wise Functions

Unit 3: Everything is Relative: Linear Functions
Lesson 7 of 10

Objective: SWBAT interpret key features (domain,rates of change) of graphs of piece-wise functions; SWBAT model and critique models of everyday situations by creating piece-wise functions.

Big Idea: Students model the many adventures of hobbit Frodo Baggins while exploring the concept of domain AND learning how to graph piece-wise functions!
