Not a whole lot of people live in South Dakota, but there are 4 people there who really rock. Carved into the rocky side of Mount Rushmore are the faces of 4 great presidents: George Washington, Thomas Jefferson, Teddy Roosevelt and Abraham Lincoln. And when we say giant, we mean it: it’s carved into the side of a South Dakota mountain! Their heads are 60 feet tall, and the mountain is hundreds of feet tall, so chipping out those faces was no easy job. Every day from 1927 to 1941, over 400 men and women worked as drillers, carvers, and cooks for the group. Many carvers hung swinging from steel cables to do their work. 90% of the rock was blasted away with dynamite, then they swung back to carve and polish by hand. Since they spent money on the project too fast, the sculpture was never totally finished. But we can still tell which presidents are looking out at us.
Wee ones: Find 3 things in your room that are chunky like rocks. Line them up from biggest to smallest.
Little kids: President Roosevelt is the one with the mustache. How many presidents are sitting to his right? Bonus: Workers would sell rocks to visitors. If you sold 1 rock for $2, how much money would you have to get for a 2nd rock to have $10 total?
Big kids: The tops of the presidents’ heads are 500 feet above ground. Since their heads are 60 feet tall, how high off the ground are their chins? Bonus: If you sell rocks for either $2 or $7 apiece, how many combinations of the two could you sell to make $23?
Wee ones: Items could include a shoe, a board book, a balled-up sock, a real ball, or a real rock! See which one is biggest and which is smallest.
Little kids: 2 presidents (Washington and Jefferson). Bonus: For $8.
Big kids: 440 feet. Bonus: Only 2 possibilities: one $7 rock and eight $2 rocks, or three $7 rocks and one $2 rock. You can’t sell 0 or 2 big rocks, because then the leftover is an odd number, and you can’t fill that by selling $2 rocks.
