What This Standard Means
What Students Need to Do
- Students read numbers through 100 shown as numerals, sums of place values, or number words. They write a given number as a numeral and as tens plus ones.
What Mastery Looks Like
- A student reads standard, expanded, and word forms accurately through 100. The student writes a spoken or written number in standard and expanded form, including numbers with zero ones.
Common Misconceptions
- Students may reverse digits, read 14 as forty-one, or confuse forty with fourteen. They may write 42 as 4 + 2 instead of 40 + 2. Numbers with zero, such as 50 and 100, can cause confusion.
How to Assess It
- Show 36, 30 + 6, and thirty-six, then ask students to read each aloud. Say “eighty-two” and have them write 82 and 80 + 2.
