Maggie's Invention POW #2 (Back to home page)

One of Maggie's classmates admired Maggie's book holder invention.  He examined Maggie's invention carefully.  Then, suddenly, he whacked himself on the head and said, "I've got a great idea!  Maggie, if you can make a stick with notches for me, we can make it together!"

He gave Maggie a wooden stick 12 inches long.  He told her, "I need notches cut in this stick, like the first couple you cut in your stick.  They need to be 1 and half inches apart and start 1 inch from one end."  Maggie took the stick and cut the notches.

How many notches did Maggie cut in the stick?  What do you think the invention is?
