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

The Year 5 curriculum for Spring in Multiplication and Division Week 1 delves into the multiplication of two-digit numbers by a single digit, reinforcing the National Curriculum objectives. Students are expected to recall multiplication and division facts for tables up to 12 × 12, use place value and derived facts for mental arithmetic, and understand the commutativity and factor pairs in calculations. They will also learn to multiply two- and three-digit numbers by a one-digit number using a formal written layout. Key vocabulary for this unit includes terms such as multiplication, division, decimals, and factors, among others. To help students visualise the process, place value counters and worksheets are provided, and the lesson plan suggests using vocabulary cards for clearer definitions of terms like expanded method, short method, and exchange.

The lesson begins with a recap of previous learning, where children apply their knowledge of exchanging in addition to multiplication. They start by revisiting the expanded method of multiplication before transitioning to the formal short method, using place value counters to aid their comprehension. Students are shown how to convert 20 ones into 2 tens and add them to the tens column, gradually building up to the concept of short multiplication. For instance, when multiplying 4 by 5, they learn to exchange 20 ones for 2 tens and then add these to the product of multiplying the tens by 5. The lesson includes solving word problems to apply these skills, and differentiated sheets are available to cater to varying levels of understanding, from working towards the expected level to greater depth, where students are challenged to create place value charts and solve multi-step problems.
