Match Numbers with Words 21-50

Continue building number word fluency with numbers 21–50! This interactive activity helps first graders master the patterns of written numbers: twenty-, thirty-, forty-, and fifty-. Understanding these patterns is key to reading and writing larger numbers with confidence.

• Levels 1–3: Match numerals to their word forms (21–30, 31–40, 41–50)
• Level 4: Challenge round — match words back to numbers!

What you’ll learn:

• Recognize the “-ty” pattern (twenty, thirty, forty, fifty)
• Understand how numbers like 23 are written as “twenty-three” (with a hyphen)
• Master tricky spellings like “forty” (not “fourty”) and “thirteen” vs. “thirty”
• Build a strong foundation for counting beyond 50
