Number Names 1 to 100 Worksheet

How do we write 48 in words? Which numeral matches seventy-two? Learning number names connects the digits children recognise with the words they read, say and write. For example, 48 and forty-eight represent the same number.

Use this number names 1 to 100 worksheet for practice with English number words. The reference lists, worked examples and additional questions below support writing numbers in words and converting words back into numerals. For Class 1 learners, introduce a manageable range at a time rather than expecting all one hundred names in a single session.

Number Names 1 to 20: Build the Foundation

Begin with the names from one to twenty. These provide the words needed for many larger numbers. Read each numeral and its name together, then cover the word and try writing it.

Give extra attention to eleven, twelve, thirteen, fifteen and eighteen. Recognising a word and spelling it independently are different skills, so allow a word bank during early writing practice.

Learn the Tens and One Hundred

The tens words make it easier to read and write numbers beyond twenty. Practise these anchor words before combining them with ones.

Remember that 40 is spelled forty, not fourty. The names fifty and eighty also need careful attention. At 100, the name changes to one hundred.

How to Write Numbers from 21 to 99 in Words

For a two-digit number beyond twenty, identify its tens and ones. In 48, the four represents four tens and the eight represents eight ones. Write the tens name first, followed by the ones name: forty-eight.

Standard English uses a hyphen between the tens and ones words in compound number names from twenty-one to ninety-nine. Whole tens, such as sixty, do not need a ones word or a hyphen.

Read Number Words and Write the Numeral

Practise the connection in both directions. When reading seventy-two, recognise seventy as seven tens and two as two ones. The numeral is 72. For ninety, write 90 because there are nine tens and zero ones.

Watch the digit order. Twenty-four is 24, while forty-two is 42. Writing the tens and ones in a place-value chart can help children check that their numeral matches the words.

Common Number-Name Mistakes to Check

Compare teen numbers with tens: thirteen is 13, but thirty is 30; fifteen is 15, but fifty is 50; eighteen is 18, but eighty is 80. Show their quantities using tens bundles and individual counters.

Check the value and spelling separately. If a child writes “fourty-two” for 42, they may understand the value but need to correct the spelling of forty. If they write forty-two for 24, revisit place value and the order of the words.

A Practical Routine for Learning Number Spellings

Choose a small set of number names. Read each numeral and word together, copy the word once, cover it and try writing it independently. Compare the attempt with the model and correct only the part that needs attention.

Mix familiar words with a few new examples. Practise twenty-one, thirty-one and forty-one together to notice the repeated ones word. Include short dictation and words-to-numerals tasks so practice goes beyond copying.
