What This Standard Means
What Students Need to Do
- Students read printed numerals through 120 aloud. They keep reading when a number sequence crosses 99 or 109.
What Mastery Looks Like
- A student reads 98, 99, 100, and 101 in order, then says 102 comes next. They read 105 as one hundred five and 120 as one hundred twenty.
Common Misconceptions
- Students may read 105 as fifteen or one hundred fifty. They may skip 100 after 99 or confuse 109 with 190.
How to Assess It
- Show students two number strips: 98, 99, 100, 101 and 108, 109, 110, 111. Ask them to read both strips aloud, say what comes next, and read a separate card marked 120.
