Addition, Subtraction, Multiplication and Division - Division using Factors - Planning

In the third week of the Autumn term, Year 6 students delve into the concept of 'Division using Factors' as part of their study on the four operations of number. The lesson is structured to begin with a starter activity that prompts students to recall what they have previously learned about division. The teaching input for the class involves exploring how factor pairs can be used to simplify division problems. For instance, students are asked to compare the process of dividing 780 by 20 directly, to dividing it first by 10 and then by 2, discussing why both methods yield the same result. This concept is further reinforced through independent practice where students apply the same technique to different division problems, and through a plenary session that consolidates their understanding.

As the lesson progresses, students tackle more complex division calculations that do not involve divisors which are multiples of 10, and they engage in solving word problems that require the understanding of a dozen as a group of 12. Group work encourages reasoning and the sharing of strategies, highlighting patterns such as doubling the quotient when dividing by half of the divisor. Students are also challenged to identify incorrect factor pairs and to explain their reasoning. Differentiated worksheets and reasoning activities cater to varying levels of proficiency, from working towards expected standards to greater depth. The lesson emphasizes the importance of understanding factors, factor pairs, and their application in division, as well as common misconceptions to be aware of. The 'Give me five' reflection activity at the end allows students to evaluate their learning and the strategies they found helpful, ensuring they remember key concepts and methods for future lessons.
