Multiplication and Division (2) - Multiply 2-digits by 1-digit - Presentation

The lesson on multiplying a 2-digit number by a 1-digit number revisits the concept of short multiplication, prompting students to recall the steps of this written method. The class is encouraged to discuss and practise the process, starting with an example such as multiplying 13 by 3. Students are guided to use place value counters and the formal column method to understand and visualise the multiplication process. The lesson includes a sequence of activities where students calculate various two-digit by one-digit multiplications, reinforcing their understanding and ability to apply the method independently.

As the lesson progresses, students tackle a range of multiplication problems, from straightforward calculations to real-world scenarios involving quantities, like determining the total number of drinks in multiple boxes or the total number of sweets in several bags. They are also challenged to correct incorrect multiplications and explore reasoning statements related to multiplication, such as whether the product of a two-digit number by a one-digit number always has three digits. The lesson aims to build fluency and confidence in multiplication, encouraging students to discuss and remember key points of the column method, ensuring they start with the correct column and follow the steps accurately to arrive at the correct product.
