hundreds frame 2.4

For a practical demonstration of its functionality, please visit the free online version of the hundreds chart available at www.lernsoftware-mathematik.de/prototypen/hunderterfeld.html.

This digital learning tool serves as an interactive mathematical manipulative designed to facilitate exploration and comprehension of fundamental operations such as addition and subtraction. Users can manipulate virtual double-sided counters within a structured hundreds chart framework, observing the resultant changes in the associated mathematical expressions. Through repeated interaction with multiple representations, learners can develop a more profound understanding of these basic operations. This feature is particularly beneficial for students with dyscalculia, as it provides visual support for grasping the concept of place value.

While the tool does not include predefined exercises, it functions effectively as a visual aid to interpret and solve various school or homework problems involving addition and subtraction. Its interactive design allows for flexible use across different learning contexts.
