# NA1-2: Know the forward and backward counting sequences of whole numbers to 100.

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.

Teaching resources for this Achievement Objective

This is an activity based on the picture book 100 Things

Students will be able to identify the sets within sets, especially the groups within 100 and within 10. Students will be able to use skip counting to count large sets.
