Multiplication and division - Divide 100 into 2, 4, 5 and 10 equal parts activity - Planning

In the Year 3 classroom, students embark on a mathematical journey to master the division of the number 100 into equal parts. The lesson is part of the Spring term's focus on Multiplication and Division, specifically tailored for the second week. Students begin with a starter activity that revisits concepts learned previously, setting the stage for the day's objective: dividing 100 into 2, 4, 5, and 10 equal parts. A variety of resources are available to aid learning, including worksheets, a presentation, and hands-on equipment such as a place value grid, counters, and base 10 blocks. Key vocabulary such as 'divide', 'partition', 'double', and 'half' are introduced, with the promise of vocabulary cards and definitions to be accessed online.

The lesson unfolds with a class teaching input where children explore different methods of partitioning 100 using the provided equipment. They are encouraged to discuss and identify equal parts, with the opportunity to represent the number 100 in various ways. Following this, the children engage in an activity that guides them through three distinct approaches to dividing 100 and prompts them to reflect on their preferred method and the patterns they observe. The lesson concludes with a plenary that employs a 'Give me five' technique, prompting students to reflect on their learning, the skills they've used and found challenging, the resources that supported them, and the key takeaways from the lesson. This structure not only reinforces the division concept but also fosters critical thinking and problem-solving skills.
