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

The educational resource from masterthecurriculum.co.uk provides a structured approach to teaching Year 4 students the concepts of addition and subtraction with a specific focus on subtracting four-digit numbers with one exchange. The "Fluent in Four" section serves as a revision tool where students are tasked with a series of calculations to reinforce their understanding of place value and the subtraction process. Students are encouraged to use place value counters to visually represent and solve the subtraction problems presented, such as 345 minus 129, which equals 216. This hands-on method helps to embed the concept of exchanging between columns when subtracting larger numbers.

Additionally, the resource incorporates a variety of activities to support mathematical learning. One of the tasks requires students to describe a 2D shape by identifying its properties, including the number of angles, right angles, obtuse angles, acute angles, and lines of symmetry. Another engaging activity involves completing a bar chart based on given data about groups and cookies, which aids in developing skills in data interpretation and representation. These activities are designed to be both informative and engaging, promoting a deeper understanding of mathematical concepts through practical application and visual aids.
