Multiplication and Division (2) - Area model (Base ten) - Planning

In an engaging Year 5 mathematics lesson, students explore the concept of multiplication using the area model with Base 10 blocks. The lesson starts with a small step starter that revisits previous learning, and then the class is introduced to key vocabulary such as 'multiplication', 'partition', and 'product'. The teaching input focuses on multiplying two 2-digit numbers by using Base 10 blocks to partition the numbers and create a visual representation of the multiplication process. This method helps students to understand the size and scale of the numbers involved. They learn to build an area model representing the calculation, for example, 23 × 22, by multiplying the length by the width of the partitioned numbers, and then combining these areas to find the total product.

Students then participate in group work and independent learning activities, which include using Base 10 blocks to solve various multiplication problems and engaging in reasoning tasks. One such task challenges students to critique a peer's approach to multiplication and correct any misconceptions. The plenary session allows children to reflect on what they've learned, the skills they've used, and what they found challenging. The lesson is differentiated to cater to various levels of understanding, with activities ranging from fluency to reasoning and problem-solving, ensuring all students work towards their full potential. The differentiated worksheets provide scaffolding for those working towards the expected level, while offering opportunities for deeper exploration for those working at greater depth, including finding the greatest possible product and investigating calculations from partially covered area models.
