Addition and Subtraction - Subtract two 4-digit numbers (one exchange) - Starter

In this Year 5 mathematics lesson, part of the Autumn Term's Week 4 Day 4 curriculum, students are tasked with a series of calculations that test their fluency in addition and subtraction, as well as their understanding of place value and comparison of amounts. The lesson begins with a 'Fluent in Four' revision section, where pupils must complete division and multiplication problems that lead to the number 9, and also express given amounts in pence before comparing them using comparison symbols. This exercise not only reinforces basic arithmetic skills but also helps students to grasp the concept of equivalence between different units of currency.

The main activity involves a real-world application of column addition. Students calculate the new balance of a business account after a deposit has been made. Starting with an initial balance of £65,239, they add a deposit of £15,987 using column addition to find the final balance for the day, which is £81,226. Additional exercises include solving division and multiplication problems that result in the number 503, and comparing pairs of amounts in pence and pounds to determine which is greater, equal, or less. For example, 4,392p is compared to £34.29, and 10,000p is compared to £100, demonstrating the practical application of mathematical operations and comparison in everyday contexts.
