How to teach a child to write
Let your kid color.
Give your child crayons specifically made for younger kids, and let them color. Younger kid's crayons are usually smaller and wider (more like a pebble than a stick), so they are easier to grasp.

Available choices:
[a]. Even if it's your child's first color, you want them to be able to enjoy the art. Search for crayons in the paint store..
[b]. If you find your child struggling, encourage them to draw on paper (with a larger pebble or crayon), and suggest the use of colored pencils. That will help them feel confident and ready to write..
[c]. A child as young as six may be frustrated if there aren't many crayons available from grandparents. If they have to draw crayons online, it will likely be frustrating them to show they aren't savvy with coloring..
[d]. Just like any part of the body, kids need to build up muscle and dexterity in their hands before they learn to write. If it's a nice day, take it outside..
[d].
