The zookeeper wanted to monitor changes in the lion’s weight. The lion’s current weight was recorded as 0 kilograms. The lion would be weighed every week. The lion’s weight went up in each of the first few weeks. Then, over the next four weeks, the lion’s weight went up two of the weeks and down the other two weeks. Use integers to record the change in weight from week-to-week. Arrange these integers in ascending order. Explain your thinking.
