Multiplication and division - Divide two digits by one digit 2 - Planning

In the second week of the Spring term, Year 3 students delve into the concept of dividing two-digit numbers by one-digit numbers. The lesson utilises practical resources such as Base 10 blocks and worksheets, complemented by a presentation to visually aid understanding. Key vocabulary such as 'multiplication', 'division', and 'partitioning' is introduced, with further resources available for definitions and explanations. The lesson begins with a review of prior knowledge and a set of questions to ensure students are 'fluent in four' fundamental calculations.

During the class, children are introduced to the part-whole model and the concept of partitioning numbers. An example is demonstrated using a place value chart where the number 66 is divided by 3. Students use counters to divide the number into equal parts and recognise the partition of tens and ones, concluding that the answer is 22. Similarly, they work through another example of dividing 48 by 4, where they partition the number into tens and ones before dividing, resulting in 12 in each group. The lesson encourages students to draw part-whole models in their books to represent their calculations. Differentiated activities are provided to cater to varying levels of understanding, from 'working towards' simple divisions by 2, to 'working at expected' level where children divide by 3 and create their own models, up to 'working at greater depth' where they use reasoning skills to link division to inverse operations. The lesson culminates with a reflective 'Give me five' activity, prompting students to consider what they have learned, the skills they used, any difficulties encountered, the resources that were helpful, and what they should remember going forward.
