You now have a square crossed by two diameters and by two diagonals. Number the corners thus: 1, 2, 3, 4, and the center 0. Take the corners and hold in one hand so that 1-0, 2-0, 3-0 and 4-0 are back to back. Then crease in that position. The form is a square. Lay down so that the folded corner faces you. Fold the loose back corner down to meet the front corner. Then turn over and again fold the remaining back corner down to meet the front corner, and two sails become visible. Fold back one-half of the hull to make a base, and the little boat will stand and move if breathed upon. It can be made water-tight by dipping in melted paraffine. Melt the paraffine by putting it in a double boiler with boiling water beneath.
Cardboard Modeling (Cardboard, knife, pencil, scissors)
This is another of Froebel's materials which is much used in the kindergarten. The regular kindergarten cardboard comes in large sheets measured off into inches, half inches and quarter inches by red and blue lines. These are to assist in the accurate cutting and folding of the stiff paper. The tinted Bristol board obtainable at stationery stores is also much used.
With this simple material older children acquire skill of both hand and eye. The higher school grades are now using it to a great extent in making geometrical figures, thus gaining practice in making objects after first making the working drawings for the same. A tinsmith who has had kindergarten training will find himself better equipped for his life work because of this early experience in cutting and measuring.
The directions here given assume that the unruled cardboard is used.
To score is to make a long shallow cut or scratch in the cardboard with a knife, so that it will bend easily. We give a few simple objects in the order of their difficulty.
1. Book-Mark. Draw an oblong 1 × 8 inches. Cut it out and punch a series of holes down the middle, one inch apart. Run a bit of baby ribbon in and out and thus make a simple book-mark.
2. Toy Wash-Bench. Draw and cut an oblong 1 × 6 inches. Draw a line straight across this one inch from each end, and then score these lines lightly. Bend and you have a wash-bench for doll's house.
3. Sugar-Scoop. Draw and cut an oblong 2 × 4 inches. Draw a line lengthwise through the middle. Score this line, and cut along the score one inch from each end. Score again from each end at right angles to the previous crease. Bend up the scored ends and the side, and paste the flaps together. This may be used for the toy grocery store.
4. Box. Read these directions through once. Then begin and work along as you read again, and all will be clear.
