Number Words Missing Words Worksheet for Grade 1

This free number words missing words worksheet for Grade 1 helps children read number names, notice spelling patterns, and complete a sequence with confidence. Instead of copying every answer from a model, learners fill gaps in number words, finish word sequences, write numerals for written numbers, and solve a final missing-word challenge.

Number Words Missing Words Worksheet: What Children Practice

The first section presents mixed numerals and number words from 1 to 20, such as 1, two, 3, and four. Students complete each row so the ideas appear in order. The second section uses short sequences like “one, two, __, four, __.” In the third section, learners read a word clue and write the matching numeral. The challenge asks which word belongs in a short run such as seven, eight, __, ten.

• Read and spell number words from zero through twenty.
• Use sequence order to identify a missing word.
• Match number names with numerals.
• Recognize the teen-word ending in thirteen through nineteen.
• Check spelling by reading the completed sequence aloud.

Grade 1 Learning Objective

After this printable activity, a learner should be able to complete missing number words in an ordered sequence and connect each word to the correct numeral. The work supports math vocabulary, counting fluency, and careful writing. It is especially useful when a child can say numbers correctly but still needs practice reading and spelling their written forms.

How to Use the Worksheet

Begin with an oral count from one to twenty. Point to a number chart and ask the child to say each number before looking at its spelling. Read one row together and circle the first known pair. Then ask, “What number comes next?” and “What word names that number?” Encourage the child to write lightly, reread the line, and correct one letter at a time. Keep a reference strip available for support, but cover it during the final challenge.

Worked Examples

In the sequence “one, two, __, four, __,” the missing words are three and five. In “six, __, eight, __, ten,” the answers are seven and nine. If the clue says “four, __, six,” write the numeral 5 because five comes between four and six. For “thirteen, __, fifteen,” the missing numeral is 14.

Common Mistakes

Children may write “tree” for three or leave out the h in eight. Ask them to stretch the word and compare it with a model. Another common error is confusing fourteen and forty, even though this worksheet stays within twenty. Highlight the shared “four” beginning and the “teen” ending. When a child writes a numeral for a word clue, remind them to count forward or backward one step rather than guess from the first letter.

Differentiation and Extension

For extra support, practice one row at a time and use letter tiles to build missing words before writing them. Start with 1–5, then add 6–10. For extension, ask a confident learner to create a new sequence with two missing words and trade it with a partner. Another idea is to sort cards into three groups: single-digit words, teen words, and the word twenty. Ask the child to explain the spelling pattern in each group.

Answer Guidance

Complete the first section so each row represents 1 through 20: 1, two, 3, four, 5; six, 7, eight, 9, ten; 11, twelve, 13, fourteen, 15; sixteen, 17, eighteen, 19, twenty. The word-sequence answers are three and five; seven and nine; thirteen and fifteen; and seventeen and nineteen. The numeral clues are 5, 10, 14, and 19. In the challenge, the missing words are eight, thirteen, seventeen, and twenty.

FAQs

Who is this worksheet for?

It is designed for Grade 1, with use as kindergarten enrichment or Grade 2 review.

Yes. Open the worksheet details panel to print the US Letter PDF.

A Helpful Routine for Word Reading

Use this Grade 1 number words worksheet in short, calm rounds. Read the sequence aloud before asking the learner to write. Then have the child point to the word before the blank, say the next number, and stretch the sounds in the number name. After writing, reread the entire line from the beginning. This routine links oral counting, spelling, and numeral meaning instead of treating each missing word as a separate spelling test.

Scaffolds and Extensions

For support, place a small number line or word strip beside the page and cover all but the five words needed for one row. Letter tiles can help children build three, seven, or eight before they copy the word. For extension, invite a learner to write a new five-word sequence with two blanks, exchange it with a partner, and explain why each answer fits. A quick sort into single-digit, teen, and twenty cards also reinforces the difference between a numeral and its written name.
