This is a resource I made for students to work on independently after being taught the content of the unit. I used it with core/upper level 5th grade students (Australia), but it could be used with 4th, 5th or 6th grade. Students were free to choose any task to start on, with the focus being on their application of time concepts. I have other investigations for other strands/units coming, so make sure to check back on my page. Thanks for looking!
