Mental Maths - Foundation

About This Worksheet

This Year 2 Addition and Subtraction worksheet focuses on developing crucial mental-strategies skills. It provides essential practice in using number bonds to 10, near doubles, and the 'add 10, then adjust' strategy for solving simple addition and subtraction problems. Mastering these mental math techniques is fundamental for building a strong foundation in mathematics. This worksheet aligns with the National Curriculum for Year 2, specifically targeting the objectives related to recalling and using addition and subtraction facts to 20 fluently, and deriving and using related facts up to 100. By engaging with this worksheet, children will improve their number sense, develop fluency in basic arithmetic, and enhance their problem-solving abilities. The focus on mental-strategies encourages children to think flexibly and efficiently, rather than relying solely on written methods. This, in turn, builds confidence and reduces math anxiety. The skills developed through this worksheet have real-world applications, such as calculating change when shopping or sharing objects equally. This Year 2 Addition and Subtraction worksheet offers valuable practice that solidifies understanding and promotes a positive attitude towards mathematics. Regular practice with worksheets like this helps children become more confident and competent mathematicians, setting them up for success in future mathematical learning. The emphasis on mental-strategies makes this worksheet a valuable tool for developing quick recall and efficient calculation skills.

💡 How to Use This Worksheet

This worksheet is designed to be used as a quick practice activity to reinforce mental addition and subtraction strategies in Year 2. It can be used after introducing the concepts of number bonds, near doubles, and adding/subtracting 10. Before starting, review the strategies with the children, using concrete examples and visual aids like number lines or counters. Encourage them to explain their thinking process aloud as they solve each problem. For differentiation, provide number lines or counters for children who need extra support. For children who are confident, encourage them to create their own similar problems. Common mistakes to watch for include forgetting to adjust after adding or subtracting 10, and misremembering number bonds. An extension activity could involve children working in pairs to create their own mental math problems for each other to solve, focusing on the strategies covered in the worksheet.
