What This Standard Means
What Students Need to Do
- Students say number names in order without always starting at 1. They continue across changes such as 29 to 30 and reverse the sequence through 10.
What Mastery Looks Like
- Given 47, a student can say 47, 48, 49, 50, and continue correctly. Given 16, the student can count down through 10 without skips or reversals.
Common Misconceptions
- Some students restart at 1 instead of using the given starting number. Others skip a decade change, confuse teen numbers, or count backward by changing only one digit.
How to Assess It
- Ask each student to continue these sequences aloud: 58, 59, ___, ___, ___ and 14, 13, ___, ___, ___. Listen for correct order and smooth transitions.

Ways to Teach It
Build a cube staircase labeled 12 through 20, then touch each cube while counting up and back.
Ask, “How do you know what comes after 39 and before 15?” Have students explain their thinking to a partner.
Draw a number card, then count forward five numbers, or count backward five numbers when the card is 20 or less.
Pretend an elevator starts on a chosen floor, then call out each floor as it moves up or down.
