Free Numbers Worksheets PDF — Grades K–1
2 ready-made word lists · Grades K–1 · 20 words total · Free printable PDFs.
Spelling number words is one of the first places where maths and literacy overlap — children who can count to ten still need to learn that "eight" has a silent gh and "four" doesn't rhyme with "tour." These worksheets give focused practice on the tricky spellings that number words are famous for, building both maths vocabulary and phonics awareness.
Pick a word list below to download a free printable numbers worksheet as a PDF — available as Word Scramble or Missing Letters for Grades K–1. Each worksheet includes an answer key. Number-word worksheets fit naturally into maths warm-ups, cheque-writing practice for older students, and cross-curricular literacy stations.

Teaching ideas for Numbers vocabulary
Match digits to words
After solving the worksheet, have students match each number word to its digit — reinforcing the connection between mathematical and written forms.
Dice spelling
Roll a die and spell the number word — students who roll a six must spell "six" correctly to keep their points. Quick, energetic practice.
Cheque writing
For older students, practise writing amounts in words as they would appear on a cheque — a real-world application of number-word spelling.
Number story problems
Have students write a maths word problem using number words instead of digits — "twelve minus seven equals…" — combining spelling with arithmetic.
