Elaboration on this Achievement Objective

This means students will know the forward number word sequence to 100 is the counting pattern of words and symbols, 0, 1, 2, 3, 4... while the backward sequence is the pattern 100, 99, 98, 97... Students will also be 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.
