Multiplication and Division - Written Methods - Worksheet

In a comprehensive lesson focused on multiplication and division, students in Year 6 are taught to multiply two-digit and three-digit numbers by a one-digit number using formal written methods. The lesson aims to help students recognise and utilise factor pairs and the commutative property to perform mental calculations efficiently. Resources provided for the lesson include differentiated worksheets, teaching slides, and Base 10 materials. The vocabulary for the session encompasses terms such as 'two-digit and a one-digit number', 'multiply', 'calculate', and 'efficient'. The lesson encourages students to explore various informal written methods for multiplication and to decide when mental calculation is more efficient than written methods.

During the lesson, children are prompted by key questions to think critically about the multiplication process. These questions include inquiries about the number of jumps on a number line and the most efficient method for calculation. The worksheet activities guide students through using Base 10 and number lines to understand and calculate multiplication problems. For example, they may be tasked with calculating 3 x 32, 3 x 15, and 3 x 28 using Base 10, or using a number line to solve 4 x 26. The lesson also includes reasoning and problem-solving components, where students must decide which multiplications to calculate mentally and which require a written method, as well as correct mistakes made in the provided examples.
