Children grow up so fast, don't they! Age-appropriate toys for kids 9 to 12 allow children to demonstrate their personality. Kids love playing fast-paced games, learning to play musical instruments, are efficient at using tablets, like listening to music, and playing silly party games. STEAM Toys & Games that allow children to use complicated problem-solving skills to build robots are also popular. Crazy Aaron's Putty is a huge hit for this age range.
