My daughter "had to" make origami acorns for next weekend's festival at school as homework. I say "had to", because I've never seen a kid be so happy about homework:)) There is more than one way to fold an acorn, and this is the easiest version. This is the kindergarten/first grade version that she's folding in the video below.
You can use a full size sheet of origami paper, or 1/4size (purchased, or cut a full-size piece into fourths). Cici is folding with a full-sized piece. If you have children 3 to 6 years of age, this is doable origami-- meaning they could fold it without help after being shown. My kids folded this version during the second year of kindergarten when they were 4-turning-5 years old.
First, fold a house !
Turn the house over, fold a flap up evenly to the bottom of the roof. Fold the sides in even with the center fold. Turn it back over, draw a face-- Owari! (All done!) My daughter made over a dozen of these last night.
Mata asobou, ne!
