Big or Small 5.1

Big or Small offers an organized framework for evaluating and enhancing children's understanding of spoken language, as well as fundamental concepts such as size, quantity, and numbers. The application is particularly useful for parents and children who may experience language delays, serving as a valuable resource to gauge developmental progress.

The inception of this app stemmed from a pivotal question for parents: At 30 months, does your child understand concepts such as “big” and “small”? This tool provides a practical means to assess children's comprehension of these concepts, while also introducing more advanced ideas such as quantity and numerical understanding, thereby facilitating ongoing development.

For international users: This app is accessible even if English is not your primary language. You may communicate instructions in your native language, allowing for a more personalized approach to learning. For instance, if the app prompts “Find a big A,” you can adapt this guidance in your own language. The focus is on grasping the concept of size rather than the specific letter. Users are encouraged to share feedback regarding the possibility of localizing the app to cater to various languages, which could also serve as an introduction to English for children given that the application includes all 26 uppercase and lowercase letters alongside numbers up to 20.

Theory behind the app: The principles of Applied Behavior Analysis (ABA) are implemented to promote positive reinforcement, thereby fostering children's motivation and engagement.
