About Year 1 Subtraction to 20 Worksheets
Is your child ready to subtract bigger numbers? These free Year 1 subtraction to 20 worksheets help children aged 5-6 develop their subtraction skills with numbers up to 20. Each worksheet uses visual supports to make subtracting from teen numbers clear and manageable.
Over five daily practice sheets, your child will learn to subtract from numbers up to 20 using counting back, number lines, and the 'subtract through 10' strategy. These worksheets build gradually — starting with subtracting small amounts from teen numbers before moving to more challenging calculations. Every worksheet includes fluency questions for speed, word problems for application, and reasoning challenges for deeper thinking.

Top Tip for Parents
If your child finds subtracting from teen numbers difficult, try working with real objects first. Count out 14 pasta pieces, take some away, and count what's left. Once they can do it physically, the worksheets will make much more sense. There's no rush — building a strong foundation now pays off hugely later.
