Make paper boats with your students in school or as a rainy day project at home with your kids. This project is appropriate for older elementary and middle school kids as it does have some degree of difficulty. Once everyone has a complete boat, set them to sail on a creek, pond or even a mud puddle. Making paper boats is cheap as it only takes one sheet of regular paper per boat.
Decorate your paper any way you want with the markers.
Lay the paper on a table with the short side facing you. Fold the paper in half top to bottom, then fold it over left to right. Unfold the paper after the second fold so you can see the crease.
Take one of the corners at the folded edge and bring the point down to the crease in the paper. Fold the paper down and crease it. Repeat with the opposite corner.
Separate the paper at the bottom and fold the top layer up. Flip the triangle over and repeat with the other layer of paper at the bottom. Fold in the excess paper at the corners of the triangle. Put your thumbs inside the opening at the bottom and pull from the middle of each side, so that the middle of each side now becomes the edge. It should now be shaped like a square.
Turn the paper upside down so the opening is facing up.
Fold both points down to the middle of the diamond to make a triangle. Open and fold in the opposite corners in the same manner as in step 4.
Grab the two loose corners at the top and gently pull them down and apart to form the boat.
Make your boats a little more colourful by using coloured paper instead of white. Use card stock for a heavier-duty boat that will not absorb as much water as regular paper does.
