As children explore their routines they are learning to make predictions about when things will occur, how often they will occur and the likelihood of them occurring. By sorting and grouping the routines they are learning about time and order. As you talk together about when routines occur children are experiencing time and exploring the different ways that we can represent time.
Time can be represented as a numeral on a clock, as an event that will happen or as something that happens at different times of the day. Time can be represented as something that happens very soon or is over quickly, as an event that lasts a long time or as something that we need to wait to happen.
When we talk about time as an event or a routine, children are developing an understanding that we will use different language to describe this rather than using a number to represent time.
