Addition and subtraction - Add two three-digit numbers not crossing 10 or 100 - Starter

In this engaging mathematics session tailored for Year 3 pupils during the autumn term's seventh week, children practise their proficiency in addition and subtraction with a focus on column subtraction. The lesson begins with a 'Fluent in Four' revision task, where students complete a column subtraction model, delving into calculations such as 35 subtract 5, and tackling division questions that involve dividing numbers like thirty-three and 53 ones by 2. This hands-on approach to arithmetic encourages students to solidify their understanding of basic operations through practical examples.

The lesson also incorporates real-life applications of maths through word problems. For instance, students are asked to determine how many bags are needed to evenly distribute 18 apples, with each bag holding 2 apples, which is a simple division problem. Additionally, they explore how to organise children into teams, with 30 children in Class 2 and 25 in Class 3, creating teams of 2 and 5 respectively. This not only tests their division skills but also their ability to combine results to find a total. Moreover, the lesson includes a measurement exercise where students are asked to calculate the mass of a person by considering different weights provided. By integrating these practical scenarios, children learn to apply mathematical concepts to everyday situations, enhancing their problem-solving abilities and critical thinking.
