Description

please check before buying the online-version of the hundreds frame at www.lernsoftware-mathematik.de/prototypen/zwanzigerfeld.html

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 twenty 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.

Using this App on an iPad is recommended because of the bigger screen size. But it also works on iPhone or iPod Touch.

To see how to use the twenty frame and all it's possibilities, watch the video at: http://www.youtube.com/watch?v=mWAxGLGoVDo.

The virtual tool doesn't provide tasks, but it can be used to solve and visualize school or homework tasks.
