SUBITIZING: Recognize quantity (usually within 5) without counting.
MAGNITUDE: Able to tell which set has more without counting.
COUNTING: Reciting of counting sequence. (Similar to singing the ABC song.)
ONE TO ONE CORRESPONDENCE: Count one number for each object.
CARDINALITY: When counting objects the last number in the counting
sequence describes the quantity of the set.
HIERARCHICAL INCLUSION: Numbers are nested inside larger numbers
PART/WHOLE RELATIONSHIPS: A number can be made of different parts. (7=1+6, 7=2+5...)
COMPENSATION: “If 5 + 1 = 6, then 4 + 2 = 6 because 4 is one less than 5, and 2 is one more than 1. One
was removed from the 5 and given to the 2 in order to get the same amount.”
UNITIZING: Grouping things to make a larger unit. Example: 10 ones equals 1 ten.
