CD-ROM storyboard sample

This is an optional loop included in a much longer CD-ROM product intended for junior high, high school, and adult learners. The product introduced advanced math concepts; the optional loops filled in basic information the learner might have missed or forgotten. The narrator was a young adult (voice only); the screen design was already established and understood by the designers. "Auto" navigation meant the CD automatically moved on to the next screen; the Next button gave control to the user.

1 I want to cover my desk with this charming paper. But how much paper will I need? Very hideous contact paper–something painfully psychedelic or covered with bright yellow rubber duckies. auto
2 To find out, I need to find the area of my desk. New screen. Word

Area

appears.
auto
3 Area tells us how large a surface is. For example, I could stick one hundred eight one-inch squares on the cover of this book. That means the area of the cover is one hundred eight square inches. Below the word Area appears a book (9 by 12 inches, but these dimensions aren’t marked yet). 108 little squares pop onto the book. The squares could look like stickers if they’re not too small already.

Below the graphic:

108 square inches = 108 in2 (make the superscript 2 flash)

4 I could have figured that out easily by multiplying the book’s length times its width. Same graphic, including the squares. Pop the dimensions on: long side is labeled 12 in & short side is 9 in.

Below the graphic, replacing the text in the previous scene:

Area = length x width

Area
= 12 in x 9 in

Area = 108 in2
