Multiplication and Division (1) - Multiples of 10, 100 and 1,000 - Starter

In this engaging mathematics session for Year 5, students tackle a variety of problems centred around multiplication and division, specifically focusing on multiples of 10, 100, and 1,000. The exercises commence with basic division, such as finding the result of 63 ÷ 9, and proceed to more complex calculations that require a deeper understanding of number properties and operations. For instance, students are tasked with dividing large numbers by 10, such as 4,200 and 982,000, and further dividing 55,000 by 1,000. The session also includes multiplication challenges where students must determine the missing factor in equations like 4 x __ = 28 and 8 x __ = 48, as well as the reverse operations, where they identify the missing dividend or divisor in equations such as ÷ 8 = 9.

The lesson continues with practical applications, such as estimating the total cost of items by rounding their prices to the nearest pound before adding them up. This real-world relevance helps students grasp the concept of estimation and its usefulness in everyday situations. Additionally, they explore more complex problems that involve multiplying and dividing by multiples of 10 and 100, like 24 x 50 and 1,200 ÷ 5. To deepen their understanding, students are asked to apply these operations to solve related calculations, further solidifying their grasp of multiplication and division. The session wraps up with a voting scenario, where students must analyse data to determine the total number of votes cast and which colour received a specific fraction of the votes, encouraging them to integrate their mathematical skills with interpretive and analytical thinking.
