NA2-2: Know forward and backward counting sequences with whole numbers to at least 1000.
This means students will know the forward number word sequence to 1000 is the counting pattern of words and symbols, 0, 1, 2, 3, 4...1000 while the backward sequence is the pattern 1000, 999, 998, 997 ... At level Two students should know these sequences in multiples of one ten (for example, 358, 348, 338...) and one hundred (for example, 247, 347, 447...) An important part of knowing these sequences is being able to name the number before and after a given number since this relates to taking an item off or putting an item onto an existing set. For example, if a set contains 800 items, 799 items are left if one is removed. This also applies to the sequence in tens and hundreds, for example, ten removed from a set of 503 results in 493 objects left.
