In this video I made a simple “Perimeter and Area Formulas” working model for Maths TLM, specially useful for Class 6–8 students. I focused on the most common shapes we use in school chapters—square, rectangle, triangle and circle—so you can quickly revise the formulas and also understand what each term means. This is not just a chart; it’s a DIY model idea you can present in school as a maths project. While making this model, my aim was to keep everything easy and classroom-friendly, using basic craft materials you can arrange at home. You can use it for explaining perimeter (total boundary) and area (space inside) side-by-side, so students don’t get confused between the two. If you are preparing a Maths working model or a TLM for geometry formulas, this project helps you show the formulas neatly in one place and makes revision faster during exams.
