Take the children for a walk and ask them to be very quiet so they can hear all the sounds around them. Stop them after a few minutes and ask them what they heard. As the walk goes on, stop every once in a while and ask the children about different kinds of sounds they may have heard. See if they heard loud or soft sounds, ones from animals, people or machines, sounds that repeated over and over and others they heard only once.
In "Simon Says," children are supposed to do whatever the leader says, but only when she says "Simon says" first. Whoever follows an instruction that does not come after "Simon says" is out of the game, and the last person in wins. The instructions can be for anything, such as touching your nose, walking in a circle or jumping up and down. The challenge for the children is to listen carefully, even if the leader is speaking quickly and they are getting excited during the game.
Clap a simple rhythm with your hands, and ask the children to clap it back to you. For very young children, start with one or two claps. Once they get the hang of that, you can add more claps and start making the rhythms more complex. Vary the tempo of the claps, from slow to fast, as well as the number of claps and how loudly you clap. This will encourage the children to concentrate.
Show the children a few simple musical instruments, such as a triangle, rhythm sticks and a bell. Have each child draw a picture each instrument on one card or piece of paper. With the children facing away from you, play the instruments in a different order each time and have the children hold up the cards in the order in which you played them. Start with one sound and work your way up to three.
