I definitely think that many teaching challenges can be tackled by making our own resources. When we don't have expensive textbooks or high-tech labs, we have to look at the "Exosystem" around us and see what we can repurpose. I have found that students actually values the resources more when they see their teacher creating them by hand. It shows them that learning doesn't require a lot of money, just a lot of creativity.

One example from my own experience is when I wanted to teach basic logic without having enough computers for everyone. I made "Logic Cards" out of old cardboard boxes and used different colored bottle caps to represent "Input" and "Output." We played a game where students had to "run the code" manually by moving the caps around. This help them to understand the core concepts of programming before they ever touched a keyboard. It turned a difficult abstract idea into something physical that they could actually feel.

Another thing I have done is creating "Mini-Libraries" using digital files on a shared offline drive. Since the internet can be blurry or slow, I collect free PDFs and open-source videos so students can access them even without a connection. This ensure that everyone has the same "data" to work with, regardless of their home situation.

Making your own resources is not just a solution for a lack of money; it is a way to make the lessons more local and relevant. When a student sees a math problem written about the local market instead of a city they have never visited, they engage with the material much faster. It's about building a "custom build" for your specific classroom needs.
