What is A Kanban?

Activity Overview

In this activity, students use the CellSheet™ Application to understand how to track inventory and predict future trends based on average daily use. They will collect data, analyze it and make predictions. They also learn to use linear regression model to predict future trends.

Before the Activity

  • Install CellSheet™ on the calculator using TI Connect™, TI-Connectivity cable, and Unit to Unit cables
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 35 - 42 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

  • Open the CellSheet Application on the calculator and start a new spreadsheet
  • Enter the daily inventory of a specified item for the past several days
  • Find the average number of items used per day and the projected starting inventory for each day
  • Identify the day when the starting inventory level is below the reserve quantity
  • Graph the day versus inventory data to find the linear equation
  • Calculate the slope, this value represents the number of items used per day
  • Find the equation of the line
  • Solve the equation and identify the day when the inventory will reach the reserve quantity
  • Compare both methods of prediction
  • Use your new skill to solve more problems on the CellSheet Application
  • After the Activity

    Students will complete the worksheet and answer questions.

    Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
