I remember when the child was 1 year old, the hand-eye coordination was not very good. I exercise in small steps, prepare several drink bottles of different sizes and some peas of different sizes and colors, and guide the children to pick up the peas in the bottles. At first, I could only put big peas in a big mouth bottle. After playing for a few days, I can put the small peas in a big mouth bottle. After a few days, I can put small peas in a bottle with a small mouth and slowly learn to put peas of the same color in the bottle. This simple little game not only exercises children's hand-eye coordination ability, but also exercises their concentration.
