Common Errors in Algebra

Resource:
Common Errors in Algebra

This is a description of common understandings and misunderstandings students have in Algebra. This could be a useful read for Algebra teachers before planning a unit.

Comparing Interest Rates

Resource:
Comparing Interest Rates

Compare the impact of different interest rates in situations about money to the function rules modeling those situations.

Comparing Models

This Core Resource supports students in investigating, primarily using rate of change, how linear functions are different than exponential functions.

All Resources From:
Comparing Rates of Change

Resource:
Comparing Rates of Change

Students start by creating definitions of linear and exponential functions by analyzing examples and non-examples of these types of functions. Students then use what they have learned about linear and exponential functions to solve word problems related to these function types. What is not covered in this resource is representing piecewise, step, or absolute functions as graphs, calculating average rate of change, and writing explicit and recursive descriptions of functions.

Comparing Rates of Change v2

Resource:
Comparing Rates of Change v2

Students compare arithmetic and geometric sequences and connect these two linear and exponential functions respectively. Students then analyze situations to determine what function type, linear or exponential, best models the situation.  

What is not yet covered in this resource is representing piecewise, step, or absolute functions as graphs, calculating average rate of change, and writing explicit and recursive descriptions of functions.

Comparing Values on a Graph

Resource:
Comparing Values on a Graph

Students will make connections between examples of verbal descriptions of the relationship between x and y and their corresponding graphs, using structural elements of linear relationships.

Connecting Exponential Function Rules to Tables

Resource:
Connecting Exponential Function Rules to Tables

Use what students know about tables and finding rate of change to connect exponential functions to their function rules.

All Resources From:
Connecting Linear and Exponential Function Rules to Tables

Resource:
Connecting Linear and Exponential Function Rules to Tables

Compare tables for linear and exponential functions to distinguish their tables and function rules.

All Resources From:
Connecting Linear Function Rules to Tables

Resource:
Connecting Linear Function Rules to Tables

Use what students know about tables and rate of change to connect these tables to linear function rules.

All Resources From:
Connecting Sequences to Equations

Resource:
Connecting Sequences to Equations

Students will look for connections between linear equations and visual sequences in order to learn how to chunk visual sequences and linear equations into parts that grow and parts that do not change. This involves one pair of students manipulating an interactive applet while other students watch and make their own connections with a partner.

All Resources From:
Connecting Situations and Equations

Resource:
Connecting Situations and Equations

Describe connections between how the rate of change and initial value are represented in a situation and its function rule.
