Get ready to dive into some fun! In this Fish Swish app, which features the hilariously quirky duck Quack, kids help Quack count fish. Quack is underwater visiting his fish friends and giving them balloon rides. In order find out how many balloons he needs, kids have to tell him how many fish there are. The only problem is there's not much time to count them! Fish swim across the screen and kids try to tell "at a glance" how many there are. The Fish Swish app was designed to promote sight counting, or "subitizing" which means seeing how many objects there are without having to count them each individually. This is a useful skill that can be improved with practice and these fish give kids a chance to do that by changing their formation and speed. Don't think the fish are trying to help though, they're really just in it for the balloon rides! The PEEP and the Big Wide World Fish Swish app was produced by WGBH and the producers of PEEP and the Big Wide World.
