As in activities for Counting Comparer (Same Size), these activities ask children to count two sets up to 5 and *use* the results of the counting to see if they are the same number (or if one has more). However, these activities challenge children to compare sets composed of different objects, often in different arrangements. Scaffolding might include explaining to a mixed-up puppet why the size of an object doesn't matter or putting the sets in one-to-one correspondence to illustrate the number comparison.

Practice-based Research: The fives and tens formats on the dot cards (also on counting cards with dots an numerals) also highlight the plus 1 growing pattern: each card has one more square filled in. When using dot cards, emphasize their visual structure and the growing pattern.
