M104:ModelingwithFunctionsofExponentialType

Modeling with Functions of Exponential Type

What will the money in your savings account be worth in 30 years? How does a coroner determine the time of death? Nature, society, business, and everyday life are full of situations in which a certain quantity depends on other measurable quantities. Function models enable us to describe, analyze, optimize, and predict what can happen in these situations.

In M104 Modeling with Functions of Exponential Type, you will:


• Create function models in situations where a quantity changes at a rate that is proportional to its value
• Solve problems and reason about situations of exponential growth and decay (such as wildlife populations, financial investments and depreciation, and radioactivity)
• Use technology as a tool to solve exponential equations and to understand how the graphs of exponential functions relate to their algebraic form

Examples of careers that use M104 concepts: economics, biology, sound engineering, and statistics.

Learning Goals

Content & Practice Expectations

Each badge framework describes the mathematics skills and understandings that students will need to demonstrate to earn each badge through a set of Content & Practice Expectations (CPEs).

Assessments

Introduction to Badge Assessments

This document provides an overview of the different badging forms of assessment.

Pre-/Post-Task

These tasks should be administered before instruction begins on a new badge and again as badge instruction comes to a close. The pre-task gives students an opportunity to see where their learning is headed, identify any relevant background knowledge or skills they already possess, and establish a starting point for the badge. The post-task provides an opportunity for students to demonstrate what they have learned and compare their new thinking to their original responses. Together, these tasks help students recognize their growth over time while providing teachers with meaningful information to guide instruction and support learning.

Performance Assessments

Each task has a teacher guide, scoring guidance, and student versions (docx format) in English and Spanish.

Portfolio Resources

A portfolio of evidence consists of student-produced artifacts that demonstrate proficiency against a badge’s CPEs. The portfolio development process involves students selecting and reflecting on artifacts that showcase their understanding of badge CPEs, followed by iterative teacher review and student-teacher conferencing until the work demonstrates proficiency.
