Littleplayer is more flexible than standalone applications. Littleplayer is more economical than outgrown grade or subject specific software. Littleplayer is more entertaining than standard flashcards. A variety of early learning and elementary materials are available with many containing graphics and/or audible prompts in languages such as Vietnamese, Spanish, Russian, German, French, or Italian. Our growing CalK series of files is based on the Kindergarten Mathematics Standards as set forth by the California Department of Education. Dozens of files are currently available with more in development. Simply add new files as your needs change, or remove files your students outgrow. Many of the files reward correct answers with brief, graphical interludes such as caterpillars changing to butterflies, birds leaving their nests, or jalopies racing by. Multipacks and site licenses are available.
