Do your students have trouble with elapsed time? It can be a tricky skill, but I have learned a few things that help my students to be successful!
1.) Read the problem once and then discuss or think about the story. Is it in order? What does the story tell you?
2.) Read the story a second time and think about SEE … S=Start time, E=Elapsed time, and E=End time. What does the story tell you and what does the question ask you?
3.) Make a number line that shows what you know.
4.) Use the number line to find what is missing. I use “mountains and hills”. The mountains are hours and the hills are minutes.
5.) For initial lessons, consider color coding. Try using green for start, red for end and any other color for elapsed. Eventually switch out to pencil, but refer back to the color coding for students who need that support.

Elapsed time! Such a difficult concept to teach and to learn (probably even for adults). I have a student teacher and I suggested she use the number line with mountains, hills, etc. It worked well for the most part. But I do like the acronym SEE! Great idea I will use for next year. I also think the color coding would have helped tremendously as well.

I really like the mountains and hills concept. I will remember that. And the pictures you include helped me understand what you were implying by that. That’s good stuff.
