Mental Maths - Challenge

About This Worksheet

This Year 2 Addition and Subtraction worksheet focuses on developing crucial mental-strategies. Mastering mental math is a cornerstone of mathematical fluency, enabling children to perform calculations quickly and accurately without relying solely on written methods. This worksheet provides valuable practice in applying number bonds, adding and subtracting multiples of ten, and using near doubles to solve problems. By engaging with these exercises, Year 2 students will strengthen their understanding of number relationships and develop a deeper sense of number sense. The worksheet aligns with the UK National Curriculum for Year 2, specifically targeting the objectives related to addition and subtraction within 100. It encourages children to move beyond counting on and back, fostering more efficient and sophisticated mental calculation skills. Developing strong mental-strategies not only improves performance in mathematics but also builds confidence and reduces math anxiety. The ability to perform mental calculations is also highly relevant in real-world situations, such as estimating costs while shopping or calculating change. This worksheet is an invaluable tool for reinforcing Year 2 Addition and Subtraction skills and preparing children for more complex mathematical concepts in the future. Regular practice with mental-strategies will solidify their understanding and build a strong foundation for future mathematical success. This worksheet offers targeted practice to solidify these essential skills.

💡 How to Use This Worksheet

This worksheet is designed to be used after students have a solid understanding of basic addition and subtraction facts and have been introduced to various mental math strategies. It's best used as an independent practice activity or as part of a small group intervention. Before handing out the worksheet, review key mental strategies such as using number bonds, adding/subtracting 10s, and adjusting numbers (e.g., adding 9 by adding 10 and subtracting 1). Differentiation can be achieved by providing number lines or hundred squares for students who need extra support. Encourage students to show their working, even if it's just a quick note of the strategy they used. Common mistakes to watch for include forgetting to adjust numbers after rounding (e.g., adding 10 instead of 9) and misapplying number bonds. For students who complete the worksheet quickly and accurately, challenge them to create their own similar problems or to explain their strategies to a partner.
