You will need a dice for this activity. Use a digital dice online if you do not have one. Alternatively, write the numbers 1-9 on little pieces of paper and turn them upside down and choose them randomly. The object is to reach as close to 1000 or 10 000 as possible (you choose the target - challenge yourself). Roll your dice (or choose your number randomly if you did the paper version) and decide which column you want to put your number. For example, if you roll a 7 and put it in the 10's column, that becomes 70. or if you put it in the 1000's it becomes 7000. After 7 rolls, see how close you are to 1000 or 10 000. You can go over, but keep as close as possible, if not exactly the target. How close can you go?
