Maths Heuristics Worksheet (Step Model)

is due tomorrow 23 Jan.

1. Remember to show all models neatly & clearly. 
2. Add the common units first, followed by the additional units as a group.
3. A Step model resembles a "staircase" with equal steps. It can also appear upside-down when the question says there is a decrease by a given number over a period of time.
