**For Teachers**

*Virginia Standard of Learning*

K.2 The student, given a set containing 15 or fewer concrete objects, will

a) tell how many are in the set by counting the number of objects orally;

b) write the numeral to tell how many are in the set; and

c) select the corresponding numeral from a given set of numerals

*Background Information from Curriculum Framewor*k

- Counting involves two separate skills - verbalizing the list of standard number words in order and connecting this sequence with the objects in the set being counted, using one-to-one correspondence.
- Association of number words with collections of objects by moving, touching, or pointing to objects as the number words are spoken. Objects may be presented in random order or arranged for easy counting.
- Kinesthetic involvement (tracing) facilitates the writing of numerals.
- Zero is both a numeral and a digit.
- Conservation of number and cardinality principle are two important milestones in development to attaching meaning to counting
- The cardinality principle refers to the concept that the last counted number describes the total amount of the counted set. It is an extension of one-to-one correspondence.
- Conservation of number is understanding that the number of objects remains the same when they are rearranged spatially.
