Unlock your child's potential and introduce them to the exciting world of programming with 'Move the Turtle' - the app trusted by parents and educators worldwide. Our fun and easy-to-use platform empowers kids with 21st century skills, helping them learn to code and prepare for a bright future! *** Winner of a Parents’ Choice Gold Award _______________________________________________ "I highly recommend it for all kids, whether or not they want to get into programming. The kind of thinking required to solve the tasks in the app is important for everyone to learn, for every field of study." -- Wired.com / Geek Dad "Are you a computer geek that loves programming or are you a classroom teacher instructing on such skills as angles, measurement and two dimensional geometry? If you answered yes to either these, then you have come to the right educational app" -- IEAR.org "I spent my formative tech-years trundling a robo-turtle around the floor while learning the Logo programming language. Now there's an app for that, although in this case the turtle is virtual" -- The Guardian _______________________________________________ *** Move the Turtle teaches children (ages 5+) the basics of programming (yes, we do mean coding!) *** Challenges and rewards keep children (with parents' assistance) & teenagers (on their own) engaged! ----------------------------------- Do you remember the Logo programming language? A friendly Turtle will introduce your child step by step to the basic concepts of programming in a colourful graphic environment. Who knows, maybe your child will be the next outstanding programmer! By completing the tasks, one after another, your child learns: *** how to plan complex activities composed of simple elements *** how to reuse previously completed work *** how to use graphics, spatial orientation and sound in programming Your child will also become familiar with the notions of loops, procedures, variables and conditional instructions. Programming is about more than completing tasks, it is also about implementing your own ideas using your imagination. With this in mind we give you the opportunity to create your own programs from scratch or based on our inspiring examples. ----- Website: https://movetheturtle.com/ Our new math app: https://correctresult.app/

Harness the incredible power of your iPad or MacOS desktop computer. Design impressive handheld gliders that you can easily put together. Create whole squadrons of your very own designs that you can make soar! Have a contest to see who can design and build the best glider. All you need is our software, along with your iPad, scissors, a metric ruler, card stock and/or balsa wood, a little clay, and a bottle of super glue (for card stock gliders) or a hot glue gun (for balsa wood gliders). This software is a true designing application that includes authentic glider analyses and predictions. It requires a bit more effort to design and build your own gliders to fly instead of just watching simulations, or using prebuilt designs, but the payoff can be well worth it. By building your own gliders you will quickly learn much more about flight, while likely feeling far more empowered and satisfied seeing your designs glide off into the distance. The software is already a great success at many schools (students 11 years old and up).
