# 1.3 - Ordinal Position

**The
student**

- given an ordered set of ten objects and/or pictures, will
**indicate**the ordinal position of each object, first through tenth.

*Adopted: 2016*

### BIG IDEAS

- So that I can tell who who finishes first, second, third in a race or game
- So that I can describe our birth order in a family
- So that I can follow the directions to a recipe in the correct order (first add the water,......)

### UNDERSTANDING THE STANDARD

- An
understanding of the cardinal and ordinal meanings of numbers is necessary to
quantify, measure, and identify the order of objects.
- An ordinal
number is a number that names the place or position of an object in a sequence
or set (e.g., first, third).
*Ordered position*,*ordinal position*, and*ordinality*are terms that refer to the place or position of an object in a sequence or set. - The ordinal
position is determined by where one starts in an ordered set of objects or
sequence of objects.
- The ordinal
meaning of numbers is developed by identifying and verbalizing the place or
position of objects in a set or sequence (e.g., the studentâ€™s position in line
when students are lined up alphabetically by first name).
- Students at
this level do not need to recognize or read the written words for ordinal
numbers (i.e., first, second, third, etc.).
- Practical applications of
ordinal numbers can be experienced through calendar and patterning activities.

### ESSENTIALS

**The student will use problem solving, mathematical communication,
mathematical reasoning, connections, and representations to**

- Identify the ordinal positions first through tenth using ordered sets of 10 objects and/or pictures of such sets presented from
- left to right;
- right to left;
- top to bottom; and/or
- bottom to top.
