Algebraic Thinking: Generalizations, Patterns, and Functions

This activity contains 17 questions.

## Using physical materials versus paper and pencil activities in patterning activities

 Encourages better distinction of the core Allows the distinction of right and wrong Allows discussion with the full class Allows students to make changes and to extend patterns beyond the spaces on the page

## The first thing to do with patterns in the upper to middle grades is to get student comfortable

 Making their own patterns Identifying the pattern core Determining when a pattern is different from another pattern Building patterns and discussing how patterns extend

## When teaching about growing patterns, students should be encouraged to do all of the following EXCEPT

 Make a pattern given a table or chart of numeric data Try to determine how each frame in the pattern differs from the preceding frame Build patterns and discuss how they can be extended in a logical manner Build or draw the first five or six frames to discover the numeric relationship of the frame number and the object

## The recursive relationship of a pattern implies

 how the pattern repeats from one part to another how to replicate the pattern in a cursive form how the previous frame is succeeded by an even number of frame how a pattern changes from step to step

## The different ways to look at the relationships in a function include all of the following EXCEPT

 Tables Diagrams Language expressions Contextual representations

## Which of the following is used as a symbol that represents a number or set of numbers?

 Variable Functional notation Linear expression Exponential equation

## Which is a true statement concerning a linear function?

 All of the points on the graph lie on a straight line As the x values increase, the y values get larger at a faster rate The y values decrease as the x values increase The y values increase as the x values increase

## All of the following statements are true about equations EXCEPT

 Equations are an expression that explains the graph Equations can be categorized in terms of the properties of an entire class of equations Equations make it easier to calculate values of the function Equations can be entered into a graphing calculator to produce a table or draw a graph

## Describe three ways to look for patterns.
