M204:ExponentialandLogarithmicFunctionsandEquations

 Exponential and Logarithmic Functions and Equations

How can we measure something that's growing really fast, like the spread of a virus or the energy released by an earthquake? Exponential and logarithmic functions are powerful tools for understanding situations where numbers grow — or shrink — by enormous amounts.

In M204 Exponential and Logarithmic Functions and Equations, you will:


• Explore how exponents and logarithms are connected as inverse operations, and learn the rules that govern them
• Read and interpret graphs of exponential and logarithmic functions, and solve equations using these tools
• Make sense of special numbers like "e" in real-world contexts, using technology to explore and visualize these functions

Examples of careers that use M204 concepts: medicine, forensic science, and finance.

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.

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.
