Here are several helpful ways to practice numbers.
Page 1 and 2 - copy sets of numbers 1-50 and 51-100.
Page 3 - fill in the blanks
Page 4 and 5 - copy each number one at a time.
Page 6 - blank 100s (one hundreds) chart
This seemed to really help my kindergarten class. They were having a hard time writing numbers properly.
I hope this helps you too.
Thank you for your time.
