Using the Sharp EL-W535B Calculator GETTING STARTED
The National Council of Teachers of Mathematics and many other organizations with a commitment to the mathematics education of our youth have all given their support to the ongoing and appropriate use of calculators. In this document, convincing arguments for the ongoing use of calculators to enhance the mathematical capabilities of students at all grade levels are presented as well as a description of the features expected to be available on calculators. The EL-W535B uses WriteView technology and allows students to enter equations as they are seen in their textbooks.
ACTIVITY AND PRACTICE SHEETS
The fifteen calculator activities and practice sheets found in this book have been designed to be used with the Sharp EL-W535B calculator. The activities have been written and developed for students in grades nine through twelve. Some of the activities will be more appropriate for students in a particular grade, while others could be used at any grade level. Of course, the classroom teacher can and should make the decision as the appropriateness of each activity. Each activity page has an objective statement and some practice key strokes. The activity page does not attempt to teach mathematics. It only identifies the mathematics being used and demonstrates the calculator key strokes necessary to conduct a calculation. The practice page provides activities for the students to practice using the key strokes presented on the activity page. Answers to the activity and practice sheets are provided at the end of this booklet.

TEACHING ACTIVITIES FOR THE CLASSROOM
The Sharp EL-W535B was designed with you and your students in mind. The following activities have been written to provide the practice students need to succeed in mathematics, as they become familiar with the wonderful features of this exciting and powerful mathematical tool.

STEP 1: Set the calculator to 2 variable statistics by pressing STEP 2: Enter 1,2 two times by pressing STEP 3: Enter 2,4 by pressing STEP 4: Enter 3,7 by pressing STEP 5: Enter 10,10 by pressing.
STEP 6: To determine the mean of the sample press. STEP 7: To determine the sample mean standard deviation for x press. STEP 8: To determine the population standard deviation for x press STEP 9: To determine the number of samples for x press STEP 10: To determine the sum of the samples for x press STEP 11: To determine the sum of squares of samples for x press STEP 12: To determine the mean of the samples for y press. STEP 13: To determine the sample mean standard deviation for y press STEP 14: To determine the population standard deviation for y press. STEP 15: To determine the sum of the samples for y press STEP 16: To determine the sum of squares of samples for y press STEP 17: To determine a press STEP 18: To determine b press.
NOTE: Other regressions can be done in a similar manner by just setting your EL-W535B to the proper STATS Mode.
