Not being very good at it myself I was recommended this package as something that would help her. It works on the idea of converting maths problems into an alien type shoot em up closely modelled on the classic space invaders.I wouldn't say that it's my daughter's favourite thing in the world to be doing, but she enjoys it more than sitting at the table while someone fires problems at her head. After the initial grumbling she can get fairly immersed in it, and has even, on the odd occasion gotten rather competitive. I would say that her maths skills are improving, so it's doing what it says on the tin, which is surely a good thing."},{"@type":"Review","reviewRating":{"@type":"Rating","ratingValue":"5.0"},"author":{"@type":"Person","name":"C***N"},"datePublished":"Reviewed in the United Kingdom on 14 May 2018","name":"\n\n\n\n\n\n\n\n \n \n Fantastic value\n \n","reviewBody":"As long as you can get it working (works in compatibility mode for XP if all else fails), it is fantastic for the money.My 5 y/o actually goes and plays this without being asked, as she enjoys the games.Of course she also likes driving her car in Test Drive Unlimited, or killing Orcs in LOTRO."},{"@type":"Review","reviewRating":{"@type":"Rating","ratingValue":"4.0"},"author":{"@type":"Person","name":"D***D"},"datePublished":"Reviewed in the United Kingdom on 3 January 2018","name":"\n\n\n\n\n\n\n\n \n \n Four Stars\n \n","reviewBody":"good product for kids, very fast delivery as well."},{"@type":"Review","reviewRating":{"@type":"Rating","ratingValue":"5.0"},"author":{"@type":"Person","name":"N***G"},"datePublished":"Reviewed in the United Kingdom on 27 April 2017","name":"\n\n\n\n\n\n\n\n \n \n Five Stars\n \n","reviewBody":"Awesome game, my son loves it and it's really helping his maths whilst making it fun also!"}],"aggregateRating":{"@type":"AggregateRating","ratingValue":4.5,"bestRating":5,"ratingCount":4}}
