3rd Grade Math - Math Galaxy

"The French mathematician Jacques S. Hadamard found, in a study of 100 leading mathematicians [including Einstein], that the majority of them were primarily visual in their approach."
Scientific American, Sept., 1984, p. 56.

The secret to learning math is consistency.
Ten minutes or ten problems a day, if done consistently, can yield significant results.

Math Galaxy’s Third Grade Math covers all of the Common Core math standards for 3rd grade as listed below.
The concepts are presented in bite-size pieces and there is an unlimited supply of practice problems, with numbers chosen randomly.
Illustrations are used throughout to reinforce the concepts.
There are review sections and you can be guided through problems step-by-step or just give the final answer.
By solving problems students earn robots to use in a maze game, plus there are several other games involving math practice.
Certificates with scores and summaries of scores can be emailed to be printed.
A stylus is recommended for iPhones.
