Up, Up and Take Away - PowerPoint

In this engaging and interactive PowerPoint presentation, primary school students are invited to help Joe, who is passionate about numbers, with a unique problem. Joe's hot air balloon is too heavy to take off because it's filled with too many numbers. The aim of the lesson is to practice subtracting numbers within 20, and the children are tasked with helping Joe lighten his load by taking away some of the numbers from his balloon. This visual and story-like approach is designed to capture the children's imagination and make learning subtraction an enjoyable experience.

As the students embark on their mathematical journey with Joe, they are presented with a series of subtraction problems that they must solve to assist him. To help with these calculations, a number line is provided, which serves as a useful tool for visualising and understanding the subtraction process. The problems range from simple subtractions like 18 – 2 to more challenging ones such as 19 – 16, catering to varying levels of proficiency and ensuring that all students can participate. By the end of the presentation, the children will have not only helped Joe's hot air balloon take flight but also reinforced their subtraction skills within the number range of 20, all while having fun with numbers.
