Look for a pencil sharpener in your local craft store, or store that carries the crayola brand pencils. You will be able to find a pencil sharpener that is compatible with the extra large-shaped tips. Find a hand held sharpener so your little ones can do it by themselves. Consider using a jumbo eyeliner pencil if you can not find a regular over-sized sharpener. This will work great, given the soft waxy nature of the Crayola Write Start pencil lead.
Show your kids how to sharpen the pencil before letting them have a turn. Gently insert your pencil so it fits snugly inside the opening of the sharpener.
Try holding the pencil and the sharpener vertically to eliminate the possibility of the lead catching and breaking off after the removal of the pencil.
Grab a trashcan and position yourself directly over top of it. When you sharpen your pencils, the tiny bits of wood and lead will go into the trash, not onto the floor.
Gently and slowly turn the sharpener in a clockwise direction, until you start seeing wooden shavings fall off from the bottom of the sharpener. Turn it about three or four turns, then take the pencil out of the sharpener to observe the length of the lead.
Check to see if the lead is slightly above the wooden base of the pencil. If you can see the color poking out, you can use your pencil. It is not recommended to sharpen the tip as high as it will go, because it will be more likely to break off and you will waste your lead.
Put your pencil back into the sharpener and give it about two more turns, if you have not seen the colored lead yet.
