First, read the English article below.

They can pick their own teams, or you can assign teams. If there are children playing, be sure to assign an adult to head each team. If there are many people playing, make teams of 3 or 4. Each team should have an even number of people.  If your guests are all different ages, consider pairing some of the younger guests up with the older ones. This will prevent any advantages and disadvantages between the groups. A great way to organize teams is by having people count off in numbers, such as 1 and 2. All of the 1s will be in one group, and all of the 2s will be in another. Another great way to organize teams is by having people pick colored slips of paper from a hat. All of the blue slips will be on one team, all of the red slips on another, and so forth. The guests should have enough time to find most of the items. How long the scavenger lasts will depend on how many items the guests have to find. An hour is a good place to start if there are a lot of items. It is also recommended for door-to-door scavenger hunts.  For very young children (preschool age) limit the scavenger hunt to no more than fifteen minutes. This will be long enough to keep the kids entertained, but short enough to keep them from getting bored. If the item list is very simple or short, 30 minutes should be enough. This will make it easier for them to carry everything. It will also prevent small items from getting lost. If the hunt has younger players, have an adult carry the container. This will allow the children to run about freely, collecting the items. It will also prevent the items from getting lost if the child trips, falls, and drops the container. If the players are only taking pictures or writing the item down, you don't need to give them this. Here are some items that you can use as a container:  A basket, especially with a handle, will be the easiest to carry. A sack or bag will be cheaper than a basket. Consider a paper bag instead of a plastic one. Paper bags hold their shape better, so the items will be less likely to get...
