How to play: Divide the children into teams (before playing, the teacher can have the children draw lots or play rock-paper-scissors to determine the order of play). When the teacher mentions the name of a shape, the children must walk into that shape (e.g., if the teacher says square, the children must walk into the square, if the teacher says rectangle, the children must walk into the rectangle), if they step into the wrong shape, they must give the turn to the opposing team and vice versa.

Purpose: Provide and help children remember the knowledge of the current topic in a more synthesized way. Stimulate curiosity and the desire to learn in children.
Preparation: A grassy board with pathways created by the teacher leading to each house. Three identical houses are placed on that board. Inside each house are different images, and one of the three houses has an image matching the one outside (e.g., in the theme 'Animals,' the teacher places a house with an image of a chicken, a house with an image of a cat, a house with an image of a rabbit, and an image of a cat using toys outside the house).
How to Play: Open the door of each house in turn to check if it is the right house. When the door is opened, revealing an image, the child will perform a gesture or sing a song corresponding to that image.
Note: When arranging the houses, the teacher should place the house to be found in the last position. This game can be applied to activities where children become familiar with music and the surrounding environment. When having children perform based on the images, the teacher can let each child express individually or have groups of children perform. During the game, those who perform well will be rewarded to encourage children to participate.
