Decimal Number Line: Project Completed

I am posting a follow up of the lesson I co-taught with a fifth grade teacher.   The earlier post shows the number line that I made for students to model their number line after.  I had planned to have students do a different section of hundredths so that we would have a large number line from 0 to 1 tenth compiled of different students’ number lines.  I decided not to have them do different numbers than I had shown on my own number line because I saw that students were struggling with the idea of counting by thousandths in discussion before they did the task.  The whole project took about 2 days for almost all students to finish.  Below I have pictured two of the  students’ number lines that turned out well.  None of the groups quite had time to write the midpoint between two different hundredths like I have in blue….five thousandths, fifteen thousandths, twenty-five thousandths etc.  Even though students muddled through this and had a difficult time getting started, I would do this lesson over again.  I probably would spend more time examining decimal number charts first so that students would more quickly recognize number patterns to write them on a number line.  To save yourself some time if you want to build these number lines see the measurements I used in my earlier post.
