Multiplication and division - Multiply two digits by one digit exchange activity - Planning

In Year 3, during the second week of Spring term focused on Multiplication & Division, students are expected to enhance their mathematical skills by learning to multiply two-digit numbers by one-digit numbers. This lesson forms part of the National Curriculum objectives, aiming to move from mental arithmetic to more formal written methods. The key vocabulary for this unit includes terms such as multiplication, division, arrays, and repeated addition. Students begin with a starter activity that revisits previous learning, followed by a class teaching input where they explore the concept of partitioning. Using base 10 blocks, children are tasked with creating the number 23 and then multiplying it by 5, understanding that multiplication is akin to repeated addition. The lesson is supported by resources such as base 10 blocks, worksheets, and a presentation, with vocabulary cards available on the associated website.

The lesson continues with an activity where students use base 10 blocks to combine tens and ones, learning the process of exchanging when more than ten ones are present. They discover that 23 multiplied by 5 equals 115, after which they are encouraged to use partitioning on whiteboards to complete similar calculations. In the second activity, children work with digit cards to solve problems systematically, either in their books or using the teaching slides. The lesson is designed to cater to different levels of ability, with differentiated worksheets that help students progress from working towards the expected level to achieving greater depth. The plenary includes a 'Give me five' reflection where students consider what they have learned, the skills they have used, and what they found challenging, ensuring they remember the key points from the lesson.
