What origami handicrafts can improve children's hands-on ability?

Kindergartens often arrange some manual homework for children. How do parents choose suitable manual projects? The child's hand-brain coordination ability is not very sound. It is very important to choose a suitable handmade work, not too difficult, but also to exercise children's hand-brain coordination ability through hand origami. Creative hand-made origami lily is not only a simple and easy-to-learn parent-child manual work, but also can take children to play origami together. First, prepare a square colored origami, which is sold in the supermarket. Fold in half along a diagonal of the square, and then fold in half along the vertical line at the bottom to form a small triangle. Pull up the paper on it and fold it to the right. Fold it into a small square and flatten it. The reverse side is the same as the previous step. Finally, it is folded into a small square, and the corners on both sides are folded inward along the center line. Unfold the shape folded in the last step, lift the paper on it along the crease, and then fold a diamond along the crease. Finally, roll the opened parts down separately and fold them into a lily by hand.
