Students will practice adding, subtracting, multiplying, and dividing complex numbers with this coloring activity. For division, students must be able to rationalize the denominator, which includes multiplying by the conjugate.
There are 20 problems total, separated into two columns. Students simplify each expression, then look for matching answers between the columns. They color the star according to their matching answers. This could also used as a partner activity in which Partner A does the left side and Partner B does the right side.
This activity was created for an Algebra 2 level class.
This activity works very well in conjunction with my Algebra 2 Solving Quadratic Equations & Complex Numbers Unit
