Year 1 Counting to 20 Worksheets

These Year 1 counting to 20 worksheets are designed to help children build early number confidence through short, focused practice. Counting to 20 is one of the first major number skills children develop in KS1, and it supports many later maths topics including addition, subtraction, number bonds, place value and problem solving.

Children can use these worksheets to practise counting forwards, counting backwards, recognising number order and spotting missing numbers in simple sequences. The questions are suitable for home learning, classroom practice, intervention work or quick revision before moving on to larger numbers.

Counting to 20 helps children understand that numbers follow a fixed order and that each number represents a quantity. By practising with different question styles, children become more confident recognising numbers, saying them in order, and using them accurately in simple maths tasks.

Parents can use these printable counting worksheets as short daily practice at home. A child can complete one worksheet independently, then check answers with an adult and talk through any mistakes. Teachers can use the same worksheets for morning tasks, small-group support, maths centres or additional practice after a lesson.

For best results, children should say the numbers aloud as they work. This helps connect spoken counting with written numerals and supports stronger number fluency. Once children are confident counting to 20, they can move on to counting to 50, counting to 100, one more and one less, and simple addition within 20.
