Algebra II is primarily a skills class. Acquiring and mastering these skills will require not only working the assignments, but also identifying and correcting mistakes. Students who do not take the time to correct their mistakes are likely to repeat them. Students who analyze their work and learn from their mistakes  will derive much more benefit from the class.  Not only will they have a deeper and more enduring understanding of mathematics, but they will also become more analytical and detail-oriented in everything that  they do.
