Let’s meet a fantastic inventor named Jerry Lawson! Jerry was a super-smart engineer and game designer who loved playing and making video games. Back in the 1970s, he did something incredible that changed gaming forever. He helped develop the first-ever home video game console with interchangeable cartridges, The Fairchild Channel F. (The F stood for FUN!) This console used special game cartridges that allowed players to switch between different games easily. Jerry’s creativity and passion inspired many inventors and revolutionized the gaming industry. Thanks to Jerry Lawson for taking those first steps that led to all the incredible video games we love to play! So let’s keep our imaginations running wild, and who knows, maybe you’ll be the next Jerry Lawson, bringing new and exciting games to the world! Game on!
X & Y Grid System in Scratch
In Scratch, the X & Y grid system introduces students to the concepts of spatial reasoning and coordinate-based programming. This intuitive grid on the Scratch Stage is a visual guide for positioning sprites (the characters and objects that come to life in Scratch creations).
As students manipulate the positions of their sprites using X and Y coordinates, they grasp that the X coordinate determines the sprite’s left-right placement and the Y coordinate dictates its up-down position. This understanding lays a solid foundation for more complex programming tasks, like animating sprites across the Stage or creating interactive games.
Students also gain a deeper appreciation for the mathematical concepts of programming. And as they experiment with different coordinate values, they begin to grasp the idea of precision and the importance of accuracy in programming.
