NA3-3: Know counting sequences for whole numbers.
This means students will know the forward number word sequence for whole numbers is the counting pattern of words and symbols, 0, 1, 2, 3, 4..., ∞ (infinity) while the backward sequence is the pattern 1000 000, 999 999, 999 998, 999 997... beginning with any whole number. At Level Three students should know these sequences in multiples of one, ten, for example 358, 348, 338..., one hundred, for example 247, 347, 447..., one thousand, etc.
