Addition and subtraction - Three-digit and one-digit numbers not crossing 10 - Starter

In this engaging maths activity designed for Year 3 students during their Autumn Term, they are encouraged to master the art of addition and subtraction through practical and visual learning techniques. The exercise begins with a 'Fluent in Four' revision task, where students are asked to count money, understanding the concept of multiplication as repeated addition, and to perform calculations involving three-digit and one-digit numbers. These tasks are designed to consolidate their arithmetic skills without crossing the boundary of ten, thereby simplifying the process and enhancing their confidence.

Additionally, pupils are invited to create both an addition and a subtraction sentence based on a given picture, using one-digit numbers ranging from 2 to 9. This exercise not only reinforces their numerical skills but also encourages them to translate mathematical equations into full written sentences, thereby integrating literacy into their maths practice. To further stimulate their critical thinking, they are posed with a challenge: Can they draw a square inside a triangle, and how many straight sides will this require? This question bridges the gap between arithmetic and geometry, prompting the students to apply their knowledge in a creative context. The activity sheet provides examples to guide students, ensuring that they can approach the tasks with confidence and a clear understanding of the objectives.
