About This Topic
Time and Sequence in Senior Infants is about developing an awareness of the passage of time and the order of events. Students learn to sequence their daily routines, recognize the days of the week, and understand seasonal cycles. The NCCA curriculum focuses on the language of time, such as 'before,' 'after,' 'next,' 'yesterday,' and 'tomorrow,' rather than formal clock-reading.
This topic helps children feel secure in their environment by understanding 'what comes next.' It also introduces the idea of duration, helping them distinguish between tasks that take a long time (like a car journey) and those that are quick (like clapping your hands). This topic is best taught through active participation in classroom routines and collaborative sequencing tasks that relate to the students' own lives.
Active Learning Ideas
Inquiry Circle: The Mixed-Up Day
Give small groups a set of cards showing parts of the school day (lunch, assembly, playtime, home time) in the wrong order. They must work together to sequence them correctly and explain their reasoning to the class.
Simulation Game: The 1-Minute Challenge
Students try to guess when one minute has passed while sitting in silence. Then, they see how many times they can write their name or do star jumps in exactly one minute, helping them feel the 'length' of a minute through action.
Role Play: The Weather Reporters
In pairs, students act as weather reporters for different seasons in Ireland. They must describe what they are wearing and what the trees look like, helping them sequence the seasons and their characteristics.
Watch Out for These Misconceptions
Common MisconceptionThinking that 'tomorrow' or 'yesterday' are fixed points in time rather than relative to today.
What to Teach Instead
Use a daily 'Time Train' on the wall. Physically moving a 'Today' marker and discussing what was 'Yesterday' and what will be 'Tomorrow' every single morning helps students understand that these terms shift every day.
Common MisconceptionDifficulty understanding that a 'long time' can feel different depending on the activity.
What to Teach Instead
Use a sand timer for two different activities: one fun (playing with blocks) and one boring (waiting in line). Discussing why the timer seemed to move 'faster' during play helps them understand the subjective nature of time.
