This is a cool Maths application using which a child can learn and practice the whole number and decimal addition concept. A magic Robo in the application gives different weight measurement examples to practice. It monitors the child’s progress and paces the complexity of the problem according to the performance of the child, starting from simple whole number weight addition to weight addition involving different unit (e.g. 11 kg 100 gm + 8 kg 500 gm) and then moves to decimal addition problems. In case a mistake is made (e.g. carryover is not added),it pin-points the exact mistake and also walks through the detailed solution of the same problem in an animated way. The child can touch the Report Card icon to see the progress.
