This bundle contains seven self checking puzzle worksheets on complex numbers: one on adding and subtracting, two on multiplying, one on division and the other three are review worksheets. The answer to a puzzle will appear at the bottom of each worksheet once the solutions are found.
The first worksheet (Complex Numbers - Adding and Subtracting) features adding and subtracting like terms. All the solutions have a '7' or two. A student must watch the subtracting signs to find the correct solution.
The second worksheet (Complex Numbers - Multiplying Complex Monomials) has all answers with 900. The student must concentrate on the imaginary part to find the correct solution.
The third worksheet (Complex Numbers - Multiplying Binomials) takes the student through the 4 letter F word: FOIL. All solutions are written in a+bi form.
The fourth worksheet (Complex Numbers – Division) offers the student a variety of fractions using imaginary numbers. Each denominator will need to be rationalized by multiplying by the conjugate. There are three types of problems for the student to work through.
The fifth worksheet (Complex Numbers – Review 1) offers a review of adding, subtracting, multiplying and dividing imaginary numbers. It also makes the student work with negative radicals which are perfect squares, such as sq root -9 = 3i. Also on this worksheet is one problem of i^82 and one problem which asks the student to find the range if values of x which makes the radical complex.
The sixth worksheet (Complex Numbers – Review 2) is a review of imaginary numbers. This worksheet is a little harder than Complex Numbers - Review 1. Included on this review worksheet are a few adding and subtracting problems, but mainly different types of multiplying problems using different rules for each, and three types of division problems to reduce.
The seventh worksheet (Complex Numbers – Review 3)offers practice on adding, subtracting and multiplying imaginary numbers, as well as working with exponents (i^52) and radicals with negative radicands (sq root -52 = 2i root 13).
I hope your students enjoy the riddles as much as mine. One of my students told me it doesn't seem like homework if there is a puzzle to solve.
