Number Words Worksheet: Complete the Number Words!
Filling in missing letters to complete number words teaches children ages 4-6 to connect a numeral with its written spelling, combining early spelling practice with number vocabulary. This kind of fill-in-the-blank format also encourages careful attention to each letter, since number words often contain tricky spelling patterns that don't follow simple phonics rules.

How to use this worksheet
Look at the first numeral together and say the number word aloud slowly. Have your child fill in the missing letters to complete the word correctly, sounding out each part as they write. Continue through each remaining number, checking the completed word together once they're done.
Materials needed
- Pencil
- Eraser
Extension activities
- •Write the completed number words onto flashcards for quick review.
- •Draw the matching number of small objects, like dots or stars, next to each word.
- •Search for number words in a favorite book or on a calendar.
- •Play a number word memory match game pairing numerals with their written words.
- •Practice writing numbers in order, saying both the numeral and its word form.
Tips for parents and teachers
Watch for tricky spellings, such as eight or twelve, which don't sound exactly the way they're spelled, and offer extra support with these. Encourage sounding out each part of the word slowly rather than guessing the whole spelling at once. Celebrate their growing familiarity with number word spelling patterns.

Trace the Numbers 1-9 Worksheet for Preschoolers
Tracing the numerals 1 through 9 gives children ages 3-5 repeated, guided practice with the specific pencil strokes each number requires, building the fine motor control and muscle memory needed for independent number writing. Because tracing follows a fixed, correct path, it also reinforces accurate numeral recognition, helping children tell visually similar digits apart.
Caterpillar Counting Worksheet for Preschoolers
Counting the segments of each caterpillar teaches children ages 3-5 one-to-one correspondence — touching or marking each segment exactly once while saying a number — which is the core skill underlying accurate counting. Writing the final total in a box also connects the physical act of counting to its written numeral, reinforcing early number-writing practice.
CVC Train Worksheet: Write and Build CVC Words!
This worksheet gives children ages 4-6 focused practice blending letter sounds into consonant-vowel-consonant words, using train-car pictures as clues for words like 'dog,' 'hen,' or 'cup.' Because children both write the word and can optionally build it with Lego blocks, this worksheet reinforces the same phonics skill through two different physical actions — handwriting and hands-on construction — which helps the spelling patterns stick.
Plant Parts Worksheet: Identify and Label the Parts of a Plant!
This worksheet teaches children ages 4-6 to identify and independently label the flower, stem, leaf, and roots of a plant, moving a step beyond simple matching toward recalling vocabulary from memory. Optionally adding pulses or grains to the diagram introduces a tactile, sensory layer that helps reinforce which part is which through touch as well as sight.
Pac-Man Maze Worksheet: Count and Move!
This dice-driven maze combines counting practice with path-following for children ages 3-5, since they must accurately count dots on a die before moving Pac-Man the matching number of spaces forward. Deciding how far to move and staying on the correct path also builds early strategic thinking, as children track their current position within the maze after each turn.
Corn Seed Addition Worksheet for Preschoolers
Counting corn seeds on two ears of corn and combining them into one total teaches children ages 3-5 the core concept of addition as joining groups together, using a concrete, countable image rather than abstract numerals alone. This worksheet also builds one-to-one correspondence, since accurate addition depends on touching or pointing to each seed exactly once while counting.
Number Matching Worksheet: 0-18
This activity strengthens numeral recognition for children ages 3-5 by having them find and pair matching numbers from 0 to 18 printed on separate strips. Because the numbers are scattered rather than in order, children must recognize each digit shape on its own rather than relying on counting sequence, which builds true number recognition instead of rote list-reciting.
Addition House Worksheet for Preschoolers
This hands-on craft turns simple addition into a reusable game, as children ages 4-5 build a paper house with numbered windows and a door that can be changed with tape or number stripes. Physically swapping numbers to create new addition problems (like 2 windows + 1 door) helps children grasp that addition means combining separate groups into one total, rather than just memorizing facts.
