What This Standard Means
What Students Need to Do
- Students continue a number sequence from a given starting point, moving up or down through 120. They match groups of objects to numerals. They read and write each numeral accurately.
What Mastery Looks Like
- A student can begin at a number such as 68 and continue correctly in either direction. They read and write numerals through 120 and label counted collections accurately.
Common Misconceptions
- Students may stop at 100 or struggle with changes such as 99 to 100 and 109 to 110. They may skip numbers when counting backward, reverse digits, or count an object twice.
How to Assess It
- Exit ticket: Write six numbers after 97, count backward from 104 to 98, label a picture of 7 tens and 3 ones, then read 116 aloud.

Ways to Teach It
Give pairs linking cubes and numeral cards; students build each number with tens and ones, then write and read the numeral.
Display 98, 99, 100, and 101; ask students to explain what changes and write what comes before and after each number.
Play Number Path: students draw a starting number and a direction card, then say and record the next ten numbers.
Have students bundle 86 craft sticks into tens and ones, count the total, and make an inventory label for the box.
