6Brainpower-enrichment programs aim to develop problem-solving and learning abilities in students who wish to improve their skills. Additionally, the program may provide challenging, stimulating, and inspiring learning experiences through engagement with math and logic problem-solving for gifted students. This book accompanies a level 5 student through the school year of the problem-solving program, or it may be used independently as a learning material for major math topics in grades 9 to 11 and as a problem-solving workbook. All brainpower programs are based on a step-by-step approach for learning and problem-solving, which enables students to understand problems of increased complexity and learning approaches required for high school. Level 5 continues to equip students typically in grades 9 to 11 with problem-solving skills and addresses learning strategies. The implication for improving one's problem-solving skills and learning strategies are numerous. These include a more positive attitude toward math and science and improved thinking flexibility and creativity in all subject areas, as well as increased success on gifted academic university admissions and professional program tests (many of which are designed with an emphasis on assessing higher-order thinking and learning skills). Moreover, knowledge of a range of problem-solving strategies, coupled with experience in their application, have benefits that transcend the classroom and enter the realm of professional, social, and intellectual accomplishment.
