Hello! Let's learn about two-sided zig-zag folds. It's a fun way to fold paper so it looks like a little mountain and valley going back and forth!
Step 1: Get a long strip of paper. We will fold it like a snake that goes up and down.
Step 2: Fold the paper in one direction. Imagine folding the paper up like a mountain.
Step 3: Now fold the paper the other way. Fold it down like a valley. So your paper looks like an M or W shape!
Step 4: Keep folding the paper back and forth like this. Each fold goes in the opposite direction to the last one.
What do you see? The paper creates a zig-zag pattern that goes forward and backward.
This is called a two-sided zig-zag fold because the folds go two ways: up and down.
Isn't that fun? You can try opening and closing the zig-zag paper like an accordion!
