Through engaging exercises, children will solidify their understanding of subtraction as 'taking away' and 'finding the difference'. This worksheet encourages the use of concrete materials and pictorial representations, fostering a deeper conceptual understanding rather than rote memorization. Mastering subtraction within 20 is a crucial building block for more complex mathematical concepts later on. This worksheet helps to build confidence by providing a series of accessible problems that gradually increase in difficulty. The skills developed through this worksheet are not only valuable in the classroom but also have real-world applications, such as calculating how many sweets are left after sharing or figuring out the difference in height between two objects. By providing ample opportunities for practice, this Subtracting within 20 worksheet empowers Year 1 students to develop strong mathematical foundations and a positive attitude towards learning. Regular practice with this type of worksheet helps to reinforce key skills and identify any areas where further support may be needed. It is an invaluable tool for teachers and parents alike, supporting children's mathematical development in a fun and engaging way. This worksheet is a valuable resource for Year 1 students to practice their subtraction skills and build a solid foundation in mathematics.

💡 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. It can be used in a small group setting, as an independent activity, or as a homework task. Before starting, ensure children have a solid understanding of number bonds to 10 and can count backwards confidently. For children who are struggling, provide concrete resources such as counters or number lines to support their calculations. Encourage them to physically remove objects to represent the subtraction. For children who are confident, challenge them to create their own subtraction word problems. A common mistake to watch out for is children counting from the number being subtracted instead of counting back from the initial number. Extension activities could include playing subtraction games or using online interactive resources.
