App DescriptionPlease check the free online-version of the hundreds frame at www.lernsoftware-mathematik.de/prototypen/hunderterfeld.html to see how it works.
The learning tool provides a virtual math manipulative for exploring and understanding basic math operations (addition, subtraction). You can manipulate the virtual double-sided counts in a five-structured hundreds frame and observe the effects to the addition or subtraction term. Over the observation and manipulation of multiple representations the child gets a (deeper) unterstanding of the basic math operations. This helps especially children with dyscalculie. The child also get's a visualisation of the place value system.
The virtual tool doesn't provide tasks, but it can be used to solve and visualize all school or homework tasks. You can use it as a visual aid.
