I saw this simple cat origami procedure in www.origami-instruction.com and found it to be an interesting lesson for my grade 1 students.
The materials needed are
1) Origami paper (or construction paper cut to a perfect square).
Step 1: Fold the origami paper diagonally to make a crease.
Step 2: Fold the left corner on top of the right to make another crease.
Step 3: Unfold the triangle so it lays flat again.
Step 4: Then fold each corner upward to make the ears.
Step 5: Fold the tip of the triangle, flip the cat over and draw the details of the cat's face.
