Multiplication and Division - Multiply 3 numbers - Planning

In the Year 4 curriculum focused on Multiplication and Division, the lesson on 'Multiply 3 numbers' introduces students to the concept of multiplying three single-digit numbers. The lesson starts with a recap of previous learning, where children use arrays to understand that the order of multiplication does not affect the result, thanks to the commutative property of multiplication. They are also introduced to the associative law, which allows them to group numbers differently without changing the outcome. The class teaching input involves using cubes or counters to create visual representations of the multiplication problems and discussing the associative law's role in these calculations. Students are encouraged to explore the concept by rearranging cubes to form different arrays and observing that the product remains unchanged, reinforcing the lesson's key vocabulary: multiplication, times tables, associative law, equal, equivalent, and representation.

During independent learning, children engage in activities that further solidify their understanding of multiplying three numbers. They rearrange their counters to form various arrays and discover that despite the visual differences, the associative law ensures the product is consistent. This hands-on experience is complemented by differentiated worksheets that cater to varying levels of understanding, from 'Working Towards' to 'Greater Depth'. These worksheets challenge students to use clues, draw missing arrays, and complete tables to demonstrate their comprehension. The plenary session concludes with a 'Give me five' reflection activity, prompting students to articulate what they've learned, the skills they've utilized, and any challenges they've faced. They also make a 'Pinkie promise' to remember the key takeaways from the lesson, ensuring a comprehensive understanding of multiplying three numbers and the associative law.
