This sentence framer acts as a great study tool, which allows students to realize that imaginary and complex numbers act in the same ways that variables do in algebraic expressions. The sheet leads them from the basics (i = the square root of -1, i squared = -1, etc.) through applications to addition/subtraction, multiplication, and division. This is accomplished by leading students to connect these concepts with those they learned in Algebra 1 (FOIL for multiplying binomials, rationalizing denominators (for radical expressions) to aid in dividing complex numbers, etc.).
