Based on your search query, I would recommend ScratchJr as an excellent tool to help kids learn to code.

ScratchJr is a programming language specifically designed for young children aged 5 to 7. It uses a block-based coding system with icons instead of words, making it easy for early learners to understand and use. The interface is designed to resemble toys and art supplies, which makes it engaging and encourages exploration and creativity.

One of the key features of ScratchJr is that it helps students develop cognitive abilities such as logical thinking and problem-solving skills. This is achieved through the creation of interactive stories and games. The projects created on ScratchJr are shareable, promoting collaborative learning experiences.

Moreover, ScratchJr serves as a stepping stone for more advanced programming languages like Scratch, Java, and Python. This means that as the students grow and their coding skills improve, they can transition to more complex programming languages.

ScratchJr is a free programming language available on multiple platforms, including iPads, select Android devices, and Chromebooks. There are no hidden costs or subscription fees, making it a cost-effective solution for teaching coding to young learners.

In the classroom, ScratchJr can be used for storytelling, teaching basic mathematical concepts and logic, creating interactive collages, and introducing students to the concept of game design and programming. It can also be used to create coding puzzles for students to solve, introducing them to problem-solving and critical thinking skills.

Overall, ScratchJr is a comprehensive tool that not only teaches coding but also enhances cognitive development and promotes collaborative learning.
