Subtracting within 20 - Varied

About This Worksheet

This Year 1 Addition and Subtraction worksheet focuses specifically on Subtracting within 20, a crucial skill for early mathematical development. The worksheet provides valuable practice in mastering subtraction facts and applying them to simple problems. By working through these exercises, children will develop fluency in subtracting one-digit numbers from numbers up to 20, building a strong foundation for more complex calculations in later years. This worksheet aligns with the National Curriculum for Year 1 mathematics, which emphasizes the importance of understanding addition and subtraction as inverse operations. It helps children develop their number sense and their ability to visualise and manipulate numbers. The word problems included in the worksheet encourage problem-solving skills and the application of mathematical knowledge to real-world scenarios. Furthermore, this worksheet promotes confidence in mathematics by providing a structured and supportive environment for practice. Successfully completing the worksheet will boost pupils' self-esteem and encourage a positive attitude towards maths. Consistent practice with subtraction within 20 is essential for building a solid understanding of number relationships and preparing Year 1 students for future mathematical challenges. This worksheet offers a fun and engaging way to reinforce these skills, making learning enjoyable and effective. The focus on concrete objects and pictorial representations also caters to different learning styles, ensuring that all children can access and understand the concepts being taught. This targeted practice is invaluable for solidifying their understanding of subtraction and building a strong foundation for future mathematical success.

💡 How to Use This Worksheet

This worksheet is designed to be used as a follow-up activity after introducing the concept of subtraction within 20 to Year 1 pupils. It can be used in a small group setting, as an independent activity, or as part of a maths station. For pupils who are struggling, provide concrete resources such as counters, number lines, or ten frames to help them visualise the subtraction. Encourage them to draw pictures to represent the problems. For pupils who are confident, challenge them to create their own subtraction word problems for a partner to solve. Watch out for common mistakes such as subtracting the smaller number from the larger number regardless of the order in the problem, or miscounting when using number lines. Extension activities could include using different representations (e.g., part-whole models) or exploring related addition facts.
