Introduction, The author and editors of Discovering Geometry An Investigative Approach are. aware of the importance of students developing geometry skills along with. acquiring concepts through investigation The student book includes many. skill based exercises These Practice Your Skills worksheets provide problems. similar to the introductory exercises in each lesson of Discovering Geometry Like. those exercises these worksheets allow students to practice and reinforce the. important procedures and skills developed in the lessons Some of these problems. provide non contextual skills practice Others give students an opportunity to. apply geometry concepts in fairly simple straightforward contexts Some are more. complex problems that are broken down into small steps . You might assign the Practice Your Skills worksheet for every lesson or only for. those lessons your students find particularly difficult Or you may wish to. assign the worksheets on an individual basis only to those students who need. extra help One worksheet has been provided for nearly every lesson There are. no worksheets for Chapter 0 and the optional tessellation lessons have been. combined into two worksheets To save you the time and expense of copying. pages you can give students the inexpensive Practice Your Skills Student Workbook . which does not have answers Though the copyright allows you to copy pages. from Practice Your Skills with Answers for use with your students the consumable. Practice Your Skills Student Workbook should not be copied Students parents and. mentors can also download the student worksheets from www keymath com .
