It is important to focus on a variety of sequencing tasks to build student flexibility with numeral order, and this task and its variants can help provide that variety. For an independent activity that is appropriate as a follow-up to this whole-group activity, separate a deck of 0-100 cards into families, 0-9, 10-9, 20-29, 30-39 etc. Shuffle the cards within each of these families and ask students to put them in order. For a small group, pairs or as independent activity, students can take a deck and sequence it, read it forward and backward, and even turn the cards face down and then name the numbers before turning the cards back over to check.
