This is a timeline of Ontario, from the ice ages to today.  We had little time to do this, we can continue at a later time. Some students worked very quickly and others slowly.  Both did quite well.   I am happy with the second example.  This student needs a lot of support but she still managed to do some of the coding with my support.  She did what she wanted to do and did some of the code for the timeline.  Given more time, this students would have been able to complete the entire work successfully.  She understood what needed to be done and understood the steps to do it.
