During a motor skills observation, which statement best describes a six-year-old's development if they can kick a ball and jump but cannot hop or balance?

The most appropriate description of the six-year-old's development in this scenario is that they are demonstrating delays in gross-motor developmental milestones. At this age, children typically master a variety of gross motor skills, including not just kicking a ball and jumping, but also hopping on one foot and balancing. The ability to hop and balance is usually expected to develop around the ages of four to six. Since this child can perform some gross-motor tasks but is missing significant milestones like hopping and balancing, it indicates that there are indeed developmental delays present.

Choosing this response reflects a comprehensive understanding of typical gross motor development during early childhood, highlighting that while some skills are present, the absence of others suggests a need for further assessment or possible intervention to support motor skill growth.
