Second Grade PLTW

 Second graders have been working on learning how computers work. They played a game called "Rosie's Runtime" where they had to get Rosie the Robotic Dog back home by giving her exact directions in the form of command cards. Just like a computer, Rosie has to be told exactly what to do through "code", or a computer program. These are directions people give, and computers will doing nothing more and nothing less than what their program says. Students would hand their cards to "Rosie", (usually played by their classroom teacher), trying to get her home with her dog bones. If Rosie did not make it home successfully, they had a "bug" in the program and needed to go back and fix it.

 Students collaborate with each other to write the best program for Rosie to follow. She has to pick up both of her dog bones and get back home without stepping in any mud puddles!

 After 2nd graders learned that you have to give computers commands in order for them to do what you want them to, they learned how to use the app, Scratch Jr. In this app, they created a "scorekeeper". They created characters and wrote code for these characters so that they could use their project to keep score as they played a math game with a partner.

Students use the scorekeeper program they created in Scratch, Jr. so they could give themselves a point whenever they won a round of the math game. The scorekeeper included two soccer goals and a soccer ball. The winner of the math game is whichever student had the soccer ball reach their goal first!
