Next: Jumps on the Number Line (0 to 20) →

This free number line activity takes children beyond twenty and all the way to one hundred. The line is marked in jumps of ten: 0, 10, 20, 30 and so on, up to 100. For each question, the child reads the number and clicks the correct mark on the line.

Working with tens helps children see how big numbers are spaced out and how counting patterns repeat. It is a friendly bridge between counting one by one and understanding place value. Great for Grade 1 and Grade 2 learners, and a quick warm-up before any maths worksheet.

How to play

  1. Look at the number line. It starts at 0 and ends at 100, with a mark at every ten.
  2. Read the number shown in the question, for example 40 or 70.
  3. Click or tap the mark on the number line where that number belongs.
  4. Check the feedback, then move on to the next question until all eight are done.

Your child practises skip counting in tens, reading a scaled number line and judging where a number sits between two marks. These skills sit right under place value: a child who knows that 60 is six tens from zero finds two-digit addition and subtraction much easier later on. The activity also builds careful looking, as the child must match the number to the correct position rather than guess. If your child hesitates, count the marks together out loud ten, twenty, thirty and point as you go. A few minutes a day is enough to build confidence.

Frequently asked questions

What age is this number line activity for?
It suits most children aged six to eight, usually Grade 1 and Grade 2. Younger children who already count confidently to 100 can also try it, and older learners can use it as a quick revision warm-up.
Why is the number line marked in tens instead of ones?
Marking every ten keeps the line clear and easy to read. It also helps children notice the counting pattern 10, 20, 30 and understand that each jump is worth ten ones, which is the first step towards place value.
How can I help my child at home?
Count the marks aloud together before answering, pointing at each one. You can also draw a simple number line on paper and ask your child to hop a pencil along it while saying the tens out loud.
Is this activity free and does it need an account?
Yes, it is completely free and no login or personal details are needed. Parents and teachers can use it on a phone, tablet or computer, at home or in the classroom, as often as they like.
