Mental Maths - Challenge

About This Worksheet

This Year 2 Addition and Subtraction worksheet focuses on developing essential mental-strategies. Mastering these strategies is crucial for building number sense and fluency. This worksheet provides valuable practice in applying different mental methods to solve addition and subtraction problems, helping Year 2 students move beyond relying solely on counting. By encouraging the use of mental-strategies, students develop a deeper understanding of number relationships and become more confident in their ability to manipulate numbers. This increased confidence translates to improved performance in more complex mathematical tasks later on. The worksheet aligns with the National Curriculum for Year 2, specifically targeting the objectives related to addition and subtraction within 100. It also helps develop problem-solving skills as students must choose the most appropriate strategy for each problem. Furthermore, the ability to perform mental calculations is a valuable life skill, used in everyday situations such as calculating change or estimating quantities. This Year 2 Addition and Subtraction worksheet provides targeted practice to solidify these mental-strategies, making it an invaluable resource for teachers and students alike. Regular practice with this worksheet will enhance their mathematical skills and build a strong foundation for future learning. It is a great tool to reinforce the concept of mental-strategies in Year 2 addition and subtraction.

💡 How to Use This Worksheet

This worksheet is designed to be used after students have been introduced to various mental strategies for addition and subtraction, such as partitioning, using number bonds, and adjusting numbers. It's best used as an independent practice activity or as part of a small group intervention. For students who are struggling, provide concrete manipulatives like base ten blocks or counters to help them visualise the numbers and strategies. Encourage them to talk through their thinking process. Common mistakes include forgetting to adjust when using compensation strategies (e.g., adding 9 by adding 10 and then subtracting 1) and misapplying partitioning. For an extension activity, challenge students to create their own addition and subtraction problems and explain which mental strategy they would use to solve them.
