Activity reflection:
In this activity, most children can draw watermelons in a certain order and draw semi-circular slices. In the process of putting forward painting requirements, there are too many requirements, which are repeated with teaching and demonstration, and the key requirements are not highlighted. The guidance is not prominent, and cotton swabs can be used when drawing watermelon seeds, so that children's clothes and fingers are not easy to get dirty and hygienic.
