## CHAPTER 4

### INTRODUCTION

Many people use a diary, an electronic day-timer or a calendar to keep track of all the things they have to do. They often plan their days and their weeks to be sure they have enough time for everything they want to do and as a reminder to get everything done. The Internet provides calendars for people to use on their computers or to print.

You will plan your activities for one week using a calendar. On the calendar you are to show how you use your time after school and on the weekend.

During the weekdays you must plan for:

130 minutes for homework
25 minutes for chores
180 minutes for other activities (your choice, such as watching TV, playing with friends, reading etc.).

On the weekend, you must plan for:

85 minutes of homework
90 minutes for chores
180 minutes for exercise.

You may also schedule other events in which you will participate.

### THE PROCESS

1. Find one way to create your schedule for each of the activities (homework, chores, and other activities). Check to make sure that the totals are correct.

2. Add any other events or activities that you take part in. Be sure to keep track of the total number of minutes for the week. If the numbers are large, you may use a calculator to find your total.

3. Go to one of the following websites and choose a calendar to create you schedule.

You may also use our one-week calendar and enter your own dates.

4. Enter your schedule onto the calendar. Be sure to type the activity and the number of minutes for each day (e.g. homework 15 min.). Check again that your minutes add up to the required time.
