Create a pile of large foam floor mat pieces; you can also use large pieces of construction paper for this activity too. Have the children form a line at the door of the classroom and designate a finishing spot at the other end of the classroom. The students in back will need to pass the squares up to the person in the front of the line to place on the floor. Once the person has placed the mat on the floor, he moves to the back of the line. The students must successfully lay each one of the tiles onto the floor to form a bridge to cross. The game is finished when everyone in the class has successfully made it across the room. To make this even more challenging, do the activity again and put a timer on it. See how quickly the children can communicate and work together.
Lay out a large piece of banner paper. Sit all of the students on the floor in a large circle next to the paper. Hold a ball of white yarn in your hands and call out a member of the class. While holding onto the end of the yarn, roll the ball of yarn to the person you named and say something nice about her. Instruct the children to follow these directions, taking turns and calling everyone in the classroom. After a time or two around the class, see if the students can work together to stand up with the web. Moving carefully as a unit, have the students sit down beside the banner paper and begin taping the web at each of the children's points. This can make a really cool classroom decoration. Think of a saying about teamwork to write on the paper to display.
Give each student 10 building blocks and instruct them to sit in a circle. Tell them that they are going to build a house one block at a time. Students must place their one block onto the house, not moving other blocks that are in place. Explain to them that they can talk to each other to figure out how to build the house, but only the person whose turn it is may put a block on. See how big they can make the house before it falls. If the house falls, ask them to talk more to each other to come up with a better way to build the house. If the house stands, ask them why they think that their house was able to stay up.
Pick an age-appropriate book and read it aloud to the students. Group the students together and ask them to talk to each other and come up with alternate endings for the book. Have them see how many different endings they can come up with and not just stop at one ending. After five minutes, have the groups share their favorite endings with the class. Do not give the students too much time to think about endings. Children at this age do not have a necessarily long attention span and they can get off track easily. Walk around the room while they are talking and monitor their progress.
