The child will work on letter recognition, letter formation, and letter placement/sizing.
Make a tic-tac-toe board using the markers, crayons, or pen.
Let the child choose a letter (focus on the letters that are difficult for the child to form).
Play the tic-tac-toe game, taking turns, writing the letters the child chose and making sure the child forms the letters correctly and places them inside the lines you drew.
For grading, make the tic-tac-toe board boxes in smaller or bigger size.
