Here’s how it works. Open the presentation, and watch the letters be traced over in red in the exact motion that the letter needs to be made in. If it’s too fast, not to worry, the letter will start over in a couple of seconds. There is also a button to toggle that brings up a dotted line to demonstrate where the letter needs to be positioned. Each of the letters are available for individual sale. You can purchase the entire set for a better deal! If you purchase the entire set, you get a bonus slide that has all of the letters on one slide being traced out correctly!
