Multiplication and Division - Multiply 3-digits by 1-digit - Planning

In a Year 4 maths lesson centred on multiplication, students advance from multiplying 2-digit numbers by a 1-digit number to tackling 3-digit numbers multiplied by a 1-digit number. The lesson, which forms part of a week-long focus on Multiplication and Division, begins with a starter activity that prompts students to recall the multiplication method they have previously learned. The class then discusses the introduction of hundreds into their calculations in addition to tens and ones, and they are reassured that the fundamental multiplication method remains unchanged.

During the first activity, students are encouraged to articulate the steps required to solve a multiplication problem involving a 3-digit number and a 1-digit number. The process is broken down, starting with multiplying the ones, understanding the concept of exchanging when necessary, and then progressing to multiply tens and hundreds. Subsequent activities involve identifying and performing exchanges in the tens and hundreds columns, and interpreting a place value chart to determine the represented calculation. After completing differentiated worksheets, the class engages in a reflective "Give me five" exercise, where they evaluate what they've learned, the skills they've applied, including the short multiplication method and repeated addition, and what they found challenging. The lesson is structured to cater to different levels of understanding, with tasks designed for those working towards the expected level, at the expected level, and at greater depth, ensuring that all students are supported and challenged appropriately.
