Rewrite simple rational expressions in different forms write a(x)/b(x) in the form q(x) + r(x)/b(x), where a(x), b(x), q(x), and r(x) are polynomials with the degree of r(x) less than the degree of b(x), using inspection, long division, or, for the more complicated examples, a computer algebra system. (+) Know and apply the Binomial Theorem for the expansion of (x + y)n in powers of x and y for a positive integer n, where x and y are any numbers, with coefficients determined for example by Pascal’s Triangle.1 For example, the polynomial identity (x2 + y2)2 = (x2 – y2)2 + (2xy)2 can be used to generate Pythagorean triples. Prove polynomial identities and use them to describe numerical relationships. Identify zeros of polynomials when suitable factorizations are available, and use the zeros to construct a rough graph of the function defined by the polynomial. Know and apply the Remainder Theorem: For a polynomial p(x) and a number a, the remainder on division by x – a is p(a), so p(a) = 0 if and only if (x – a) is a factor of p(x). Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication add, subtract, and multiply polynomials. The program scores these attempts, and new test scores are displayed for both student and teacher.Īrithmetic With Polynomials And Rational Expressions Teachers can be creative when setting up scoring, requiring students to work a specified number of questions, reach a set goal of two or three correct answers in a row, or just earn back a partial point for answers reworked correctly. Because the teacher has pre-linked each test item with a skill, students are automatically assigned a practice set tailored to their needs. Through the test correction assignment, students are asked to indicate which problems they missed. A detailed solution is shown after every submitted answer, so observant students can easily learn from their mistakes and improve as they work. You can filter by Common Core State Standard (CCSS), grade level, or module to create assignments tailored to classroom needs, and you can look through each assignment, or view students' most recent attempts, to see both the individual questions attempted and the answers submitted. Along with multiple-choice questions, fill-in-the-blank prompts, and timed challenges, question sets also include interactive modeling.

All a student needs is an email address and a teacher-provided code or link to join. Students can easily locate upcoming, completed, and past-due assignments on their dashboard - even if they have been enrolled in more than one DeltaMath class. Group students within a section, or pit one class against another to see which can reach a set goal or maintain the highest success rate. Creating a warmup with unit prerequisite skills and then linking a test correction activity to guided question sets could help struggling students keep up with the class. Student problem logs update fairly quickly, so they're the perfect scorekeeper for whole-class challenges. Teachers shouldn't limit their use of the test corrections to unit assessments. It could also be a helpful option to reteach and remediate anyone who may need a little review. Online Camps for a Summer of Learning AdventuresĭeltaMath's standout feature is the ability to link test items as test corrections. It does take some time to set up and link each test item - especially for longer assessments - but the individualized activities and self-scoring make up for this additional work. The problem log may seem overwhelming at first as it shows a time-stamped receipt for every question completed by every student however, search options help filter through the clutter by student name, assignment, or skill.Workshops for Middle and High School Families.Workshops for Families with Kids Age 0–8.Digital Citizenship Resources for Families.
