ü  Identify place value of digits up to a million. [M.2.2.a]

ü  Write numbers in basic expanded form (e.g., 6091 = 6000 + 90 + 1). [M.2.2.b]

ü  Demonstrates an understanding of the values of digits up to a million (e.g., that in 21,054, the 1 represents 1,000). [M.2.2.c]

ü  Name and write, in numerals and words, whole numbers to 10,000. [M.3.2]
