Addition and subtraction - Add two-digit numbers not crossing 10 - Planning

The curriculum for Year 2 in Autumn focuses on enhancing addition and subtraction skills, specifically adding two-digit numbers without crossing the ten's threshold. National Curriculum objectives include using concrete objects, pictorial representations, and mental strategies to add and subtract. Children learn to combine two-digit numbers with ones and tens, as well as adding two two-digit numbers and three one-digit numbers. They also tackle problem-solving involving these concepts. The key vocabulary for this unit encompasses terms such as addition, subtraction, partition, and exchange, which are crucial for understanding the mathematical operations and their applications. The lesson plan encourages the use of interactive tools like ten frames and manipulatives to aid learning.

In Lesson 16, students are introduced to adding two-digit numbers without crossing ten. Using resources like Base 10 blocks, place value grids, and worksheets, teachers guide students through the process, emphasizing starting with the ones when using the column method. The lesson includes practical activities where children create number stories and represent problems using Base 10 to understand the value of digits in different places. As they progress, children move from concrete to more abstract representations, such as part-whole models and bar models, to demonstrate their understanding. The lesson aims to build fluency in addition and provide differentiated learning paths for children working towards expected levels and those capable of greater depth. The plenary includes a "Give me five" reflection, where students consider what they've learned, the skills they've used, and what they found challenging, ensuring they consolidate their knowledge and address any misconceptions.
