This activity practices solving incomplete quadratic equations by taking square roots. The equations are in VERTEX FORM. Solutions are rational (integers and fractions) and irrational numbers. The amusing part is finding an idiom corresponding to each solution sets of the partners鈥� quadratic equations labeled with one and the same small alphabetic letter.

Activity Directions: Students start solving their own set of twelve equations by the square root method. They are given tables to use. Using table 2, each partner finds which two words correspond to each solution set of his equations. At last partners together rearrange the words corresponding to their equations labeled with one and the same small alphabetic letter and find out an idiom. They find out 12 different idioms and write them in table 3.

Answer keys are included.
