Number Ordering 1 to 20 Worksheet | Kindergarten Missing Numbers and Number Order

This number ordering worksheet kindergarten helps kids practice number sequence 1–20 in a simple, confidence-building way. Children look at short number patterns like 1 _ 3, 8 9 _, and 18 _ 20, then write the missing number to complete each sequence.

To support handwriting and number formation, kids also trace the missing numerals as they fill them in. A clear 1–20 number line is included at the bottom as a reference, so students can check their work independently. Perfect for kindergarten math centers, morning work, homeschool practice, intervention, or quick review. Builds number order, counting fluency, and early math confidence.
