ENDLESS FUN FOR YOUR KIDS Let the children try to build their own construction vehicles and enjoy hours of fun. Each piece can be disassembled or reassembled repeatedly. Parents can accompany their children to play together, and can present the functions of each engineering vehicle to children to expand their knowledge. So What Skill Will Your Child Develop? By trying to figure out how to match the pieces the toy trucks have to stabilize them together, your child will develop multiple cognitive skills. First of all, your child will learn some problem-solving skills which will turn out very helpful at school and later in their everyday life. In addition, they will improve their hand-eye coordination and achieve fine motor skills all while playing!
