Overview

Students investigate a table of values and observe

patterns in the table. Students use v on the

TI-30XS MultiView™ calculator to enter data into a list

and test their generalizations.

Introduction

The warm up question is given to help you launch the

student sheet activity. You can skip the warm up

activity but you will have to provide more guidance

during the investigation of the problem on the

student sheet.

Warm up

Guide students in the use of tables and v to see a

pattern and write a generalization. Present the

following story problem.

Every Wednesday, Keisha gets home from work too

late to walk her dog, Max. She asked her neighbor

Kyle to walk her dog after he comes home from

school. Kyle is happy to help! Keisha pays Kyle $4

each week to walk Max. Kyle likes to save his money.

Create a table of how much money Kyle has each

week for 5 weeks.

Guide students to create the following table on their

papers. You can think of this table as a data list of

two numbers which depend on each other. It is

important to have students write their calculation

and outcome in the Money (output) column in order

to see any patterns. This helps them to write

algebraic sentences from the words and to make

generalizations using inductive reasoning.

Use these columns for different

learning styles if needed.
