Before After 100 Practice Activities
Printable preschool and kindergarten activities for naming the number that comes before or after numbers up to 100.
Practice that builds confidence
What children learn
These Before After 100 practice activities help preschool and kindergarten children strengthen number order as they count toward 100. Children practise telling which number comes just before or just after a given number, using familiar counting patterns.
The printable worksheets include simple number prompts, missing-number tasks, and counting-sequence practice. Activities are designed to build confidence with the number line, one-more and one-less language, and accurate number recognition through 100.
Before and after work helps children understand that numbers have a fixed order. When a child sees 47 and writes 46 before it or 48 after it, they are connecting counting aloud with written numerals. This supports early place value awareness, especially when crossing tens such as 29 to 30 or 59 to 60.
How the practice progresses
Children begin with familiar counting sequences and move into individual number prompts up to 100. Some items ask for the number after, some ask for the number before, and some place the given number in the middle of a short sequence. This variety helps children avoid guessing and encourages them to think about the direction of the count.
Parent routine at home
Choose one worksheet section and read the directions together. Ask your child to point to the given number, whisper the counting sequence around it, and then write the missing number. For example, for 72, say “71, 72, 73” while touching each space. Keep a hundred chart nearby if your child needs support, then gradually cover it for a few questions.
Classroom uses
Teachers can use these pages for morning work, small-group counting review, math centers, or quick checks after number-order lessons. The worksheets also pair well with number cards: students can build a three-number sequence with cards first, then complete the matching printed task independently.
Common errors to watch for
Many children reverse before and after, especially when the prompt is not in a full sequence. Others skip over a decade number, writing 20 after 18 or 40 before 39. Watch for reversed numerals too, such as 51 written as 15. Encourage children to count one step at a time instead of relying only on memory.

Helpful answers
Frequently asked questions
What skill do these Before After 100 worksheets practise?
They practise identifying the number that comes immediately before or after a given number up to 100, helping children strengthen counting order and one-more, one-less thinking.
Are these worksheets suitable for both preschool and kindergarten?
Yes. Preschool children can use them with support such as counting aloud or a hundred chart, while kindergarten children can use them for more independent number-order practice.
Should my child use a hundred chart while completing the pages?
A hundred chart is helpful at first, especially for numbers near 10, 20, 30, and other decade changes. As confidence grows, try covering the chart for a few questions.
What is a good way to explain before and after numbers?
Use a short counting sequence. For 56, say “55, 56, 57.” Explain that 55 is before because it is counted just earlier, and 57 is after because it comes next.
Which mistakes are common with numbers up to 100?
Children may mix up before and after, skip decade numbers, or reverse digits such as writing 63 for 36. Encourage them to point, count slowly, and check the sequence.
