Before After 100 Practice Activities
Printable Nursery, LKG and UKG counting activities for finding the number before and after any number up to 100.
Practice that builds confidence
What children learn
These Before After 100 practice activities help Nursery, LKG and UKG children build confidence with counting order from 1 to 100. Children practise identifying the number that comes just before and just after a given number.
The printable worksheets include simple number-sequence tasks, missing-number boxes, and child-friendly numeral practice. Activities move from familiar smaller numbers towards two-digit numbers, supporting careful reading and stronger number sense.
Before and after work teaches children that every number has a position in the counting order. For example, 36 comes after 35 and before 37. This is more than memorising numbers; it helps children understand one more, one less, and how numbers are arranged from 1 to 100.
How the practice develops
The worksheets begin with clear, direct tasks such as writing the number before or after a given numeral. Children then meet small sequences with blanks, such as 48, __, 50 or __, 72, 73. This gradual movement helps them connect counting aloud with written numerals, especially across tricky changes like 29 to 30 or 59 to 60.
Parent routine at home
Use a short daily counting routine with objects your child can see, such as buttons, crayons, or steps. Say a number, ask “What comes before?” and then “What comes after?” If your child is unsure, count three numbers together: 64, 65, 66. Then return to the question. Keep a number chart nearby so the child can point, say, and write.
Classroom uses for teachers
Teachers can use these printables during maths practice, revision, morning work, or small-group support. They also work well in counting centers: one child reads the number, another answers before or after, and both check on a hundred chart. The pages help teachers quickly notice who can count by memory and who still needs visual support.
Common errors to watch for
Many young learners reverse the direction and write the after number when asked for before. Others may struggle at decade changes, writing 40 before 39 or 70 after 69 incorrectly. Some children can say the answer aloud but form digits backwards while writing. Encourage them to slow down, circle the given number, and check whether the word says before or after.

Why iBloom worksheets help
iBloom worksheets give repeated, focused practice without overloading the page. The clean layout keeps attention on the counting skill, while varied blanks prevent children from simply copying a pattern. A helpful child strategy is: “Find the number, count one step back for before, one step forward for after.”
Helpful answers
Frequently asked questions
What does “before and after 100” mean for Nursery, LKG and UKG children?
It means practising the number that comes just before or just after a given number within the range 1 to 100, such as 54 before 55 and 56 after 55.
Should my child know all numbers to 100 before using these worksheets?
A child should be familiar with counting aloud for at least part of the range. The worksheets can still be used with a number chart for support while the child builds confidence.
Why does my child make mistakes at 29, 39, 49, and similar numbers?
Decade changes are common trouble spots because the tens digit changes. Counting slowly around the number, such as 28, 29, 30, helps children hear and see the pattern.
How can I help if my child confuses before and after?
Ask the child to point to the given number on a number chart. Move one step left for before and one step right for after, saying the words aloud each time.
Can these worksheets be used in a classroom maths centre?
Yes. They are useful for small-group practice, revision, independent counting work, and quick checks of number-order understanding up to 100.
