In fourth grade math the emphasis is on multi-digit multiplication and division with multi-digit dividends, developing an understanding of fractions and decimal fractions, plus developing fluency in addition and subtraction.
Math Galaxy’s Fourth Grade Math covers all of the Common Core math standards for fourth grade as listed below.
The concepts are presented in bite-size pieces with an unlimited supply of problems, with numbers chosen randomly.
Illustrations are used throughout to reinforce the concepts.
You can be guided through problems step-by-step or just give final answers.
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 can be emailed from final-answer mode to be printed.
A stylus is recommended for iphones.
Topics covered are listed below along with their Common Core standard.
More details on common core standards can be found at: http://www.corestandards.org/Math/
