What This Standard Means
What Students Need to Do
- Students say 10, 20, 30, and so on up to 100. They keep the numbers in order without counting every number in between.
What Mastery Looks Like
- A student counts aloud by tens from 10 to 100 without a chart. If they pause at 60, they can name 70 as the next number.
Common Misconceptions
- Students may skip a number, such as going from 40 to 60. Some say 100 after 90 but do not know that 100 is the end of this count.
How to Assess It
- Ask each student to count aloud by tens from 10 to 100. Then ask, "What comes right after 70?"
