Divide the group into teams (based on size), and give them each a large glass container. The object is to fill their containers with as much materials as they can. The materials are rocks, stones, gravel, sand etc.. (But you can use anything.) The larger materials should be placed in the container first, and then followed by the next to the largest, and so on... In this order you should be able to fit the most into the container.
You can come to your own conclusion for the activity based on your need. The rocks (due to size) would be the most important items to complete. (Can be home activities...work/life balance.) Then stones would be every day has to finish items. Gravel can be the projects that need completed. Sand could be the extra work that was just assigned to you.
Allow the groups to fill their own container without detailed instructions. Tell them to fill their containers with as much materials as they can. And then we talk about the order they selected. If they had an order...and what the materials represents to them...etc. Use this communication to lead into training by saying the jar is the day u have (24 hours) u can fill it up with sand (not so important tasks) and have no space for the bigger stones (very imp tasks) or fill it up smartly and then in the end pour a cup of coffee into it.. to emphasize.. u r never so busy as not to have a coffee with friends n family :-)
