It is an important skill that helps develop number sense and prepare children for mental math. Learning Goals This game is designed to help children strengthen their subitizing skills as they: • Make small collections up to five without timing • Identify small collections up to five objects without counting • Learn and reinforce number names and symbols • Understand that quantity can be represented by a numeral or a set of objects • Compare sets of one to five objects and identify if the sets are the same or different • Count from one to five Jungle Gym is part of the four-game subitizing suite from Early Math with Gracie & Friends™, a first-of-its-kind mobile app brand based in early learning sciences, rigorously researched and developed specifically for preschool classroom use.
