Through specific and directed practice, students will gain confidence and competence with addition, subtraction, and multiplication of complex numbers.

Practice makes perfect!

Students will work diligently to solve a number of problems carefully selected from the textbook.

p. 522 #1 - 14 (powers of i)

p. 522 #29 - 32 (parts *a* - *c* only) (sums, differences, & products)

p. 522 #33 - 38 (complex conjugates; absolute value)

Of course, they may need help, and that's my job! I fully expect to spend a large part of the lesson working with small groups on difficult concepts, taking students to the board for explanations, and playing match-maker with students to pair up those who've figured it out with those who haven't.

Bear in mind that all of this is merely intended as breathing-room before we continue our study of complex arithmetic with division of complex numbers!
