How many of your students have memorized commercials but not their multiplication facts? Neuroscience research is emphasizing the effectiveness of 15-second ads. Ultimate Multiplication Flash Cards is a PowerPoint presentation that lets the teacher utilize the impact of subliminal messaging. The main page has a grid of numerals for multiplication facts from 0-12. Click on a specific numeral and those facts will wipe across the screen. Students will have one second to think of the answer before it automatically displays. Each set of flash cards will run in about 15 seconds and then display a link to the home page grid. Run the specific fact you are working on several times in a day as you change from one activity to another. Additional options are to post the file of the PowerPoint on your class website for students to work at home or burn CDs for students to use in the computer lab or on the classroom computer.
