Karen Tripp modified the classic "Battleship" game for homeschooling purposes.
She created the game using four laminated copies of the Periodic Table which were labeled alphabetically by row and column, then inserted into two file folders [sheet protectors?] with jumbo paper clips.Sadly, after coming up with this innovative idea, she then dumbed it down by labeling the rows A through H and the columns 1 through 18, so the children instead of calling out "phosphorus" or "cadmium" or "oxygen" just call out "D-11" or "F-4" or whatever. An opportunity missed there, I think.
“The kids can then mark where they want to place their ships by circling rows of 2, 3, 4, and 5 elements on the lower table.. They play by calling out coordinates. If they miss they put an X on the spot they chose on the upper table. If they get a hit, they circle it.”
