## Algebra II Module 1, Topic D, Lesson 37 Student Outcomes

• Students define a complex number in the form a + bi, where a and b are real numbers and the imaginary unitsatisfies i 2 = −1.  Students geometrically identify i as a multiplicand effecting a 90° counterclockwise rotation of the real number line. Students locate points corresponding to complex numbers in the complex plane.
• Students understand complex numbers as a superset of the real numbers; i.e., a complex number a + bi is real when b  = 0. Students learn that complex numbers share many similar properties of the real numbers: associative, commutative, distributive, addition/subtraction, multiplication, etc. Algebra II Module 1, Topic D, Lesson 37: Teacher Version (1.02 MB) View PDF Algebra II Module 1, Topic D, Lesson 37: Student Version (594.78 KB) View PDF Algebra II Module 1, Topic D, Lesson 37: Teacher Version (2.12 MB) Algebra II Module 1, Topic D, Lesson 37: Student Version (193.64 KB)
