## DIstance-time graphs, scientific notation and significant figures

Attached are two worksheets to practise calculating distance, time and speed (vitesse), as well as working with these in graphs.  Today we discussed how to express very large or very small values in scientific notation and how to determine significant figures, and express them when rounded off to an x number of places.     We will be working with these concepts for the next few days in different types of problems, and should be ready to be tested early next week - Tuesday, Dec. 13th.
