Fascinating Fact:
Ordinal numbers tell position. First, second, third, then fourth, fifth, sixth in a line.
In KS1 Maths, pupils learn that ordinal numbers describe place in an ordered list, such as 1st in a race or 3rd in a queue. Children match words (first, second, third) and symbols (1st, 2nd, 3rd) to real-life positions.

What are ordinal numbers for Year 1?
Ordinal numbers show position in order, like first (1st), second (2nd), third (3rd). They are used for places in a line, steps, or race results.
How do I teach first, second, third to KS1 pupils?
Use real objects in a line, label positions with cards (1st, 2nd, 3rd), and ask children to describe who is first, who is last, and who is in between.
