This activity is designed to be used for groups of 4 members! It includes four different multiple - choice quizzes each of eight radical equations and a brief biographical text of NASA research mathematician Katherine Johnson (to be completed).
Students will practice solving radical equations reducible to linear and quadratics. Extraneous solutions are included. The radical equations contain:
- a monomial and/or a binomial under a radical symbol
- a radical expression on one side of the equation and a monomial or a binomial on the other side
- radical expressions on the both sides of the equations (“radical equals radical”)
Most of the equations require rearranging and isolating the radical and the rest are set up to square both sides. All the equations require squaring once.
Activity Directions: Students solve all the equations. The answers they get will give them pieces of a brief biographic story about the American scientist Katherine Johnson. It can stimulate student interest in Math and provide a role model for all students. Recording sheets are provided for students to show all work.
Answer keys are included.
