Teacher's field guide

What Students Need to Do: Students begin with any given number below 100 and continue counting by ones to 100. They keep the sequence accurate through each change to a new decade.
What Mastery Looks Like: Given 47, a student says every next number through 100 without restarting at 1. The student moves correctly from 59 to 60, 69 to 70, and through later decade changes.
Common Misconceptions: Students may restart at 1, repeat the starting number, or skip a number when the tens digit changes. They may also stop at a familiar benchmark such as 50 or 90.
How to Assess It: Tell the student to begin at 68 and count by ones to 100. Note any restart, skip, repeat, or incorrect decade change.

Lesson moves

Lay number cards from 40 to 100 with selected cards missing, then start at a chosen card and fill gaps while counting.
Ask, "What number comes after 79, and what changes in the number name when we reach it?"
Play start-and-pass, where one child draws a starting number and classmates continue the sequence around the circle.
Begin an inventory at 63 classroom items, add one item at a time, and continue the running count to 100.
