Multiplication and Division - Multiply by 10 - Presentation

The lesson on 'Multiply by 10' is an engaging and interactive session aimed at enhancing students' fluency and reasoning skills in multiplication and division. The lesson encourages students to observe patterns and changes when numbers are multiplied by 10. Through a series of activities, learners are prompted to complete sentences that help them understand the concept of multiplication by 10. For example, they are guided to recognise that each row of ten ones has a value of ten and to calculate the total by multiplying the number of rows by ten. This methodical approach is designed to solidify their understanding of place value and the effects of multiplying by 10 on different numbers.

To further reinforce the concept, students engage in practical exercises using place value counters and bar models. They are challenged to determine the correct bar models for given calculations, such as the number of passengers on buses or the number of pencils in pots. These visual aids help students visualise the multiplication process and enable them to grasp the concept with greater clarity. The lesson also includes reasoning tasks where students must decide if a statement is always, sometimes, or never true, and solve problems that require them to find possible original calculations based on given products. These activities are designed to encourage critical thinking and to deepen students' understanding of multiplying by 10 in various contexts.
