Davidson's Learning Center Series: 1st Grade (Jewel Case) Previously released as JumpStart First Grade, Davidson's Learning Center Series: 1st Grade is Knowledge Adventure's edutainment offering, targeting the educational needs of the First Grade student. It's a game-filled environment of learning opportunities. Kids can start at the playground to play the Math Marble Game, the Milk Cap trading game, or help the dog Frankie find the items he's buried. Or, if the student prefers to enter the lunch room, there is the Pizza Picker and Measuring games. Then serve up fractions for lunch or play the Cash Register game. It's all about learning and having fun in the process. In the classroom, a library of story books awaits. Play with paints, stickers, or jump on board the field trip bus. There are dozens of opportunities in JumpStart First Grade to increase reading, writing, arithmetic, language, and arts skills for five-to-seven year-old students
