 When you are standing in a line with a child, you can help them learn about first and last. To do this, you can describe the people who are first and last in the line. For example, you might say, the woman with the yellow dress is the first in line. Then you could say the man in the red shirt is the last in line. As the line changes, you can ask the child to describe who is now first and last in line. This activity will help the child learn the meaning of first and last.
