Addition Subtraction - Subtracting Within 20

About This Worksheet

This worksheet provides a valuable opportunity for Year 1 students to solidify their understanding of subtraction within 20. By working through these problems, children will develop fluency in basic subtraction facts and build confidence in their mathematical abilities. The inclusion of word problems encourages them to apply their knowledge to real-world scenarios, fostering problem-solving skills and mathematical reasoning. The use of number lines as a visual aid helps to reinforce the concept of subtraction as taking away or counting back. This visual representation can be particularly helpful for children who are still developing their number sense. The worksheet also promotes the development of fine motor skills through writing and drawing, and encourages independent learning and self-assessment. Successfully completing this worksheet will contribute to a stronger foundation for future mathematical learning, enabling children to tackle more complex subtraction problems with greater ease and understanding. The focus on subtraction within 20 is crucial as it forms the basis for understanding larger numbers and more complex operations later on. By mastering these fundamental skills, children will be better prepared for the challenges of Key Stage 2 mathematics.

💡 How to Use This Worksheet

This worksheet is designed to reinforce subtraction skills within 20 for Year 1 students. Begin by reviewing the concept of subtraction using concrete objects like counters or cubes. Model how to take away a smaller number from a larger number. Encourage children to use number lines as a visual aid to count back and find the difference. For each question, encourage children to read the problem carefully and identify what is being asked. Provide support as needed, especially with word problems, by helping them to identify the key information and translate it into a subtraction equation. Allow children to use their fingers, draw pictures, or use manipulatives to aid their calculations. Review the answers together as a class, discussing different strategies used to solve each problem.
