Description: These Algebra 2 cards work great after a lesson over complex numbers - make sure you have taught students how to simplify an imaginary number, add, subtract and multiply complex numbers, find the complex conjugate of a complex number and find the zeros of a quadratic in vertex form (students do not need to use the quadratic formula to do this). Card tasks are outlined below: Cards 1 – 5 require the students to simplify an imaginary number in terms of i (activity: drag-and-drop) Cards 6 – 10 require the students to determine the complex conjugate of the given complex number (activity: fill-in-the-blank) Cards 11 – 15 require the students to add or subtract two complex numbers (activity: fill-in-the-blank) Cards 16 – 20 require the students to multiply two complex numbers (activity: multiple-choice) Cards 21 – 24 require the students to determine the complex solutions of the quadratic in vertex form (and set equal to zero) (activity: drag-and-drop)
