Demonstrate for your students that when blocks hit different items in the classroom they create a different sound. For example, if you hit a block into another block it makes a different sound than if you hit it into the metal part of a desk. Have each of your students take a block and tell them that they are a very important part of your block band. When you give them the cue, they will start playing their block by knocking it into the place you have shown them. Make sure that they understand when you gesture to them again that they are to stop playing. The kids will have a great time hearing these different sounds when everybody is playing at once.
Since many kids are familiar with construction through toys and shows like Bob the Builder, you can indulge them with a specific construction site role-playing game. Purchase some cheap yellow construction hats for your students and get as many toy tool belts together as you can. Put up some Caution tape around the play area and tell the students that they are all working on a construction site. The students will enjoy this dramatic play exercise. Remember to tell them that they are all on the same construction team in case anybody tries too hard to be the "foreman."
Take your students on a walk around the neighborhood. Have them pay attention as best as possible to the different streets, stores, and houses near your school. When you get back to the room, tell them that you will be building a map of your town using blocks. Some of them will remember certain streets and buildings immediately. Try to let every student have an opportunity to contribute to your block map. Even if a student has made up a building, tell them the town would be better if the fictitious building was part of the area. Take a photo of the map and upload it to the parents to show them what their children think of the town.
This counting game works well with preschoolers when you are in a one-on-one setting. Explain to them how dice work, with different numbers on each side. Tell the student that you will be rolling a die to see how many blocks you should build with. Roll the die, pick up that many blocks and put them into the building you are creating together. Then have the student roll the die and help him to select the right number of blocks based on what he rolls. By the end of the game, you should have constructed a block tower together and your student will have a better understanding of the numbers 1 through 6.
