About Number Words

What this skill is

Reading number words bridges mathematical reasoning and early reading literacy, helping children translate between spoken quantity, Arabic numerals, and English orthography.

When children learn it

Reading number words from zero to ten begins in kindergarten. Reading and writing number words up to twenty and beyond is mastered in 1st and 2nd grade (CCSS 2.NBT.A.3).

Teaching Tips

  • Make flashcards pairing the digit (like 8) with its written name ("eight") and a small dot pattern. Have your child match the pairs in a memory game before completing their worksheet fill-in exercises.

Common Mistakes

  • Confusing phonetically similar words like "fourteen" and "forty" or "sixteen" and "sixty".
  • Struggling with irregular spellings like "two", "eight", and "twelve" that do not follow simple phonics rules.
  • Matching the word to the wrong digit because of visual similarity (such as pairing "three" with 8).
