Multiplication and Division (2) - Multiply 4-Digits by 1-Digit (Pictorial representations) - Presentation

The educational resource focuses on teaching students the skill of multiplying four-digit numbers by a single-digit number using pictorial representations. In this lesson, students are encouraged to apply their understanding of short multiplication to complete various multiplication problems. The lesson is structured around a series of activities where students are instructed to set out their calculations in columns, ensuring a clear understanding of the place value system, which is crucial for accurate computation. The columns are labelled as TH (thousands), H (hundreds), T (tens), and O (ones) to aid in the correct alignment of numbers. Through these exercises, students practice multiplying four-digit numbers by one digit, with an emphasis on the importance of columnar arrangement for clarity and precision in their calculations.

As the lesson progresses, students engage with activities that require them to complete calculations, write multiplication problems represented visually, and find answers. They are also prompted to consider the significance of exchanging when the value in a column reaches ten or more. For instance, in one activity, students are presented with the weekly earnings of an individual and asked to calculate the total earnings over a four-week period. The lesson further includes reasoning tasks where students must identify and correct errors in multiplication, and independent work that challenges them to use place value counters and apply logical thinking to solve problems. The lesson aims to solidify the students' understanding of multiplication, the concept of exchanging in columnar calculations, and the identification of the product in a multiplication equation.
