Missing Numbers Train Worksheet: Numbers 1-20
This worksheet helps children ages 4-6 practice number recognition and sequencing by filling in missing numbers on a train of cars that counts from 1 to 20, reinforcing that numbers follow a fixed, predictable order. Working with a range this large also builds the stamina and sustained counting skill needed before children move on to skip-counting and simple addition.

How to use this worksheet
Look at the train cars together and read aloud any numbers that are already filled in. Ask your child to figure out which numbers are missing by counting on from the numbers they can see. Have them write the missing numbers in the empty train cars in the correct order. Once complete, read the whole train's numbers aloud together from 1 to 20 to check the sequence is correct.
Materials needed
- Pencil
- Eraser
Extension activities
- •Count everyday objects around the house, going all the way up to 20 if you can find enough.
- •Draw your own number train and fill in the missing numbers for an extra round of practice.
- •Play a 'what comes next' game, saying a number and having your child say the following one.
- •Use a number line taped to the floor and have your child hop along it while counting to 20.
Tips for parents and teachers
Encourage your child to say the numbers out loud as they fill in the blanks, since verbalizing the sequence helps them notice if they've skipped or repeated a number. This reinforces number recognition and sequencing at the same time, and the teens in particular are worth double-checking since they're often the hardest part of the 1-20 range. Celebrate completing the whole train as a meaningful milestone.

Missing Numbers: Ice Cream Fun Worksheet for Kids
This worksheet helps children ages 3-5 practice number sequencing by identifying and writing in the missing numerals within a series of ice cream cones and cars, numbers 1 through 10. Filling in a gap within an otherwise familiar sequence requires children to hold the whole counting order in mind and recognize what number logically belongs in the empty spot, which is more demanding than counting forward from the start each time. The playful ice cream and car theme keeps the repeated number practice visually engaging.
Hopscotch Numbers 1-50 Worksheet: Fill in the Missing Numbers!
This hopscotch-themed worksheet gives children ages 4-6 practice filling in missing numbers within the 1-50 range, extending their number sequencing beyond the more commonly rehearsed 1-20 range and building familiarity with two-digit number patterns like the '20s' or '30s.' Framing the numbers as a hopscotch grid connects the paper activity to a familiar physical game, helping children mentally picture themselves counting forward as they move up the grid. This kind of extended-range practice is an important bridge toward comfortable counting to 100.
Before and After Numbers Worksheet for Preschoolers
This number sequencing worksheet asks children ages 4-6 to identify the numbers that come immediately before and after a given number, strengthening their mental number line and reinforcing the concept that numbers exist in a fixed, ordered sequence. This before-and-after reasoning is more demanding than simple counting because it requires children to move both forward and backward from a starting point. Building this flexible number sense supports later addition and subtraction, which both rely on moving confidently along a mental number line.
Number Sequencing Worksheet: Practice Counting and Ordering Numbers!
This worksheet gives children ages 4-5 focused practice writing numerals in order by filling in the missing numbers within several different counting sequences. Unlike simple counting aloud, writing each numeral by hand forces children to connect the spoken number word to its correct written symbol, reinforcing both number recognition and early handwriting control.
Descending Order Worksheet: Numbers 31-99
This worksheet extends number-sequencing skills for children ages 4-6 into the two-digit range of 31 to 99, asking them to arrange given numbers from largest to smallest. Working with larger numbers requires understanding that the tens digit generally determines size first, an important step toward place-value thinking. Practicing descending order, which is less intuitive than counting up, also strengthens flexible number sense.
Ascending Order Cut and Paste Worksheet for Preschoolers
This worksheet teaches children ages 4-6 to arrange numbered animal pictures from smallest to largest, reinforcing the concept of ascending order as a foundational number-sequencing skill. Physically cutting and repositioning each numbered piece, rather than simply writing numbers in order, makes the abstract idea of 'smallest to largest' into something children can manipulate and see. This hands-on approach also builds patience and careful visual comparison.
Dinosaur's Missing Numbers Worksheet: Cut and Paste Fun!
Children ages 4-6 practice number recognition and sequencing in a playful dinosaur theme, identifying which numbers are missing from a sequence and pasting them into the correct spots on a row of eggs. The dinosaur and egg imagery adds motivation and narrative context to what's otherwise a straightforward but important numeracy task — recognizing numerals and understanding their fixed order.
Before and After Numbers Worksheet: Counting Bananas!
Figuring out which number comes immediately before and after a given number strengthens children ages 4-5's understanding of number order and the counting sequence, a concept that's more abstract than simply counting objects one by one. Coloring a matching number of bananas for each answer adds a concrete, visual check, letting children confirm their number sense by physically representing the quantity. This worksheet bridges rote number-sequence memorization with real quantity understanding.
