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