Counting Practice 10S Practice Activities
Printable Class 1 maths worksheets for practising counting in 10s using number charts, skip-counting patterns, and decade numbers.
Practice that builds confidence
What children learn
These Class 1 maths worksheets help children practise counting in 10s as they move from one decade number to the next: 10, 20, 30, and so on. Children learn to see the pattern clearly on number charts instead of memorising a chant without meaning.
The printable activities include guided number sequences, chart-based practice, missing-number tasks, and simple counting routes. They are designed for early learners who are building confidence with skip counting and place value language.
Counting in 10s helps Class 1 children understand that numbers can grow in equal jumps. On a number chart, they notice that 10, 20, 30, 40 and other decade numbers line up in a predictable way. This prepares them for place value, mental addition, money counting, and reading larger numbers later.
How the practice progresses
The worksheets begin with clear forward counting patterns, then move to missing numbers and number-chart work. Children may trace or complete sequences such as 10, 20, __, 40, 50, and then identify what comes before or after a given ten. The focus is not speed; it is noticing that the tens digit changes while the ones place stays at 0.
Parent routine at home
Use a short oral warm-up before the worksheet. Ask your child to clap and count: 10, 20, 30, 40. Then point to the same numbers on a chart and ask, “What do you notice?” After one printable page, use real objects in groups of ten, such as pencils or buttons, and count the groups together. This connects the written number to a real quantity.
Classroom uses for teachers
Teachers can use these sheets during maths centres, morning practice, small-group revision, or after introducing skip counting on the board. A number chart can be displayed while children complete the page, so they learn to use visual support independently. The worksheets also work well for quick checks before moving to counting by 5s or early two-digit place value.
Common errors to watch for
Some children say the pattern correctly but write numbers like 10, 12, 13, or 10, 20, 21 because they are thinking of ordinary counting. Others reverse digits, writing 02 for 20, or skip a decade number. Encourage them to look at the ones place and ask, “Is it still zero?”

Why iBloom worksheets help
The iBloom pages keep the layout clean and the number ranges suitable for Class 1 learners. Each activity gives just enough repetition to build fluency while still using charts, blanks, and visual patterns. A useful child-friendly strategy is: “Say it, point to it, write it.” This helps children connect the sound, the chart position, and the written number.
Helpful answers
Frequently asked questions
What does counting in 10s mean for Class 1 children?
It means counting forward in equal jumps of ten, such as 10, 20, 30, 40. Children begin to recognise decade numbers and the pattern that the ones place remains 0.
Should my child memorise 10, 20, 30, 40 first?
Chanting can help, but it is better when paired with a number chart or objects grouped in tens. This helps the child understand the pattern instead of only reciting it.
How can I help if my child writes 02 instead of 20?
Show the number on a chart and say it slowly: twenty has 2 tens and 0 ones. Ask your child to check that the zero is in the ones place, not at the beginning.
Are these worksheets useful before learning place value?
Yes. Counting in 10s gives children an early feel for tens, decade numbers, and the way two-digit numbers are organised.
Can teachers use these as maths centre activities?
Yes. The pages work well for maths centres, small-group practice, morning revision, or a quick check after teaching counting by tens on a number chart.
