Author Description

ABOUT THE BOOK NOTE: THIS BOOK HAS BEEN UPGRADED. THERE ARE SEVEN SBA MODEL ANSWERS NOW, INSTEAD OF THE ORIGINAL THREE, AS INDICATED ON THE COVER. This book covers model SBAs that I developed after looking at the guidelines outlined in the CSEC Mathematics syllabus. I collected the data myself, analyzed them and wrote them into model SBAs that students will understand. Students can benefit by looking at how these SBAs are structured, written and presented. Students will get ideas how to do their own SBAs. They will also get ideas how to formulate their discussions and conclusions when they go through these answers. This book offers students the following SBA model answers: To investigate hire purchase plans at three local stores in Trinidad and compare them. To investigate and determine the current value of a privately owned vehicle after 8 years in Trinidad. This SBA will determine if a contractor’s bid of $80,000 (eighty thousand dollars) is reasonable for the replacement of the roof of the Science Lab at a Secondary School in San Fernando, Trinidad, after measurements of the roof were taken by students and Teachers and the total costing of materials, labour and the contractor’s fees were added. An investigation into bulk buying of grocery items at PriceSmart versus buying single items at the Supermarket. A statistical representation of diabetes in children in Trinidad. An analysis of the June 2020 Principles of Business CSEC results for ninety students who were registered to write this examination for Paper 1 and the submitted SBA (School Based Assessment) at a Secondary School in Trinidad. Planning and Designing an Enjoyable and Affordable Form 5 Graduation Ball. This book is designed for all form four, form five and repeater students who are currently taking CSEC Mathematics examinations and have to do SBAs.
