Based on your query, I would recommend Scratch as a suitable EdTech tool for creating digital maths content.

Scratch is a free platform developed by MIT that allows students to learn coding through the creation of interactive stories, games, and animations. It can be integrated into various subject areas, including mathematics.

One of the key features of Scratch that could be beneficial for your needs is its ability to encourage creativity and engagement. Students can design games that help practice math skills, such as addition, subtraction, multiplication, and division. This makes learning maths more enjoyable and memorable for students.

Moreover, Scratch offers a block-based programming language that eliminates syntax errors, allowing beginners to focus on logic and problem-solving. This feature can be particularly useful in teaching mathematical concepts, as it allows students to visualize and understand the logic behind mathematical operations.

In addition, Scratch promotes collaboration by allowing students to share their projects with others. This can foster teamwork and enhance the learning experience.

In summary, Scratch provides a creative and engaging platform for teaching maths digitally. Its features such as block-based programming, creativity encouragement, and collaboration tools make it a suitable choice for your needs.
