Talk to them about different light sources (sun, lamp, flashlight, lightning, etc.)
Tell your child that today you will be playing a game in the dark.
Find a dark place to play (you may need to wait until nighttime).
All the letters of their name should be printed on a piece of paper.
Mix up the letters and tape them around the room being sure they are at your child’s level.
Give your child a flashlight and tell them we are going to search for each letter so we can put their name in the right order.
Go through each letter and provide support as needed.
Once you have all the letters, be sure to go back and recall all the letters you found.
Extension:
To extend on from the above game, you can include the letters from their last name, or you could include all the letters and do a random search to help your child with all of the letters.
If your child is ready, play this game by saying the letter sound rather than the letter and encourage your child to look for the letter that matches the letter sounds.
