Summary:
Kindergarteners are fascinated with counting, often before they know how to count. This enthusiasm provides an ideal environment for learning to count to 100. Students should learn to count by ones and by tens. Learning the sequence "ten, twenty, thirty, forty,...., ninety, one-hundred" provides structure that helps children remember the sequence "twenty-eight, twenty-nine, thirty, thirty-one,...).
Understanding the Standard:
Questions to Focus Instruction:
- Can students fluently count by tens to 100?
- Can students count to 100 fluently, beginning at one?
Skills
Prior to: Students can count from 1-10.
At Grade Level: Students can rote count to 100. Students can count to 10, then to 20, then to 30, and on by 10 to 100. Students may be able to group and skip count by 2s, 5s, and 10s, although not required at this level.
Moving Beyond: Students' frustration at losing their place when counting to large numbers like 100 will encourage them to group and skip count, especially by tens. This, in turn, leads to other forms of skip counting. These are addressed in Grades 1 and 2.
