Teachers, Quick Flash II is a fabulous way to give your students practice in multiplication. In the opening screen, students can choose their starting level. After they begin, the program will progress through all of the multiplication facts in flash card style. With each correct answer, a green block will be stacked next to the flash card. Incorrect answers receive a red block. If you have your students in the computer lab, you can easily walk around and see student progress. The green and red boxes will tell you the problem multiplication facts.
