Addition and Subtraction - Adding 2 three digit numbers (no exchange) - Planning

In a Year 4 mathematics lesson focusing on addition, students learn to add two three-digit numbers without the need for exchanging (carrying over). The lesson underscores the importance of aligning the digits correctly and setting out the addition problems neatly in columns. Students start by revisiting the concept of place value and ensuring they understand when it is not necessary to exchange between the ones, tens, and hundreds columns. The lesson includes a range of resources such as chalk, outdoor materials, worksheets, and a presentation to facilitate learning. Through partner talk and practical activities, children explore different representations of calculations, such as place value mats, bar models, and number stories, enhancing their understanding of the addition process.

The lesson also incorporates outdoor learning, where children use natural materials like sticks, stones, and leaves to represent ones, tens, and hundreds. They create place value mats to solve various addition problems, which helps reinforce the value of each digit. Following this, reasoning activities challenge students to verbalise their thought processes using specific sentence stems, aiming to deepen their comprehension and address common misconceptions. As the lesson concludes, children are encouraged to reflect on what they've learned and the skills they've used, including single-digit addition and bridging ten. Differentiated worksheets are provided for independent work, with tasks tailored to support students working towards expected levels and those capable of greater depth, where they complete more complex calculations involving hundreds, tens, and ones.
