Multiplication and division - Multiply two digits by one digit 1 - Presentation

The lesson entitled "Multiply two digits by one digit (1)" is designed to strengthen students' multiplication skills, specifically focusing on multiplying a two-digit number by a one-digit number. The lesson encourages learners to utilise their understanding of multiplication facts and explores the concept of partitioning as a strategy to facilitate these calculations. Through a series of activities, students are prompted to think about how breaking down numbers into tens and ones can simplify the multiplication process. Real-world examples, such as calculating the total number of coloured balls on multiple snooker tables or gummy bears in sweet jars, are used to contextualise the mathematical concepts and engage students in practical problem-solving.

Throughout the lesson, the use of Base 10 blocks and place value counters is emphasised as a visual aid to help students grasp the concept of multiplication and its connection to addition. Activities challenge students to perform calculations using these methods and then match their results with place value counters to verify their answers. This hands-on approach not only reinforces their numerical understanding but also addresses common errors, as students are tasked with identifying and correcting mistakes in sample calculations. Towards the end of the lesson, reasoning questions prompt deeper thinking about the relationships between numbers in multiplication, such as the equivalence of halving one number and doubling the other. Independent work and group discussions further consolidate learning, as students reflect on how multiplication relates to addition, the benefits of partitioning, and the correlation between written methods and concrete representations of numbers.
