This course is the first half of a full year Algebra 1 experience for students and needs to be taken with Algebra 1B. The class will address the Massachusetts Curriculum Framework for Mathematics Incorporating the Common Core Standards for Massachusetts. The eight Standards of Mathematical Practice will be incorporated throughout the year in that it is designed to involve students in active learning, inquiry based problems and problem solving strategies to build conceptual understanding and to strengthen students' abilities to think, reason, and problem-solve using mathematical understandings and skills. Discussed, among other topics, will be rational and irrational numbers, writing and interpreting polynomial and rational expressions, creating and reasoning with equations and inequalities, interpreting and building functions including linear, quadratic and exponential models, and summarizing and interpreting statistical and probability data. Students who excel during this course will be given the opportunity, with teacher recommendation, to move into Honors Algebra 1 for the 2nd semester.
