Which motor skill would you expect children to be able to perform?

As an AI language model, I don't know the specific age of the children, but typically children at certain ages are expected to perform certain motor skills.

For example, infants may be able to grasp objects, roll, and sit with support. Toddlers may be able to walk, climb stairs, and throw a ball. Preschoolers may be able to run, jump, hop, skip, draw and use scissors. School-age children may be able to ride a bicycle, catch and throw a ball, and develop more fine motor skills such as writing.

As children grow and develop, they acquire various motor skills. Here are some motor skills you would expect children to be able to perform at certain ages:

1. Infancy (0-1 year):
- Lifting their heads while lying on their stomachs.
- Reaching and grasping objects.
- Rolling over.
- Sitting without support.
- Crawling or scooting.
- Pulling themselves up to stand.

2. Toddlerhood (1-3 years):
- Walking independently.
- Climbing stairs with assistance.
- Kicking a ball.
- Scribbling with crayons or markers.
- Beginning to feed themselves with a spoon.

3. Preschool (3-5 years):
- Running and jumping.
- Pedaling a tricycle.
- Catching and throwing a ball.
- Holding a pencil with a tripod grasp.
- Cutting with scissors.
- Tying shoelaces.

It is important to note that the development of motor skills varies between individuals, and some children may acquire certain skills earlier or later than others.
