Parents: call out the letter SOUND and let your child make the letter he/she thinks it is. If it is incorrect try saying, “Hmm if I were to make an ‘h’ I’d make it like this” then demonstrate for your child. They’ll want to fix the mistake without you even asking! You can also demonstrate by writing on a magnadoodle or dry erase board.
Make letter writing fun. Try using every color in your crayon or marker collection. See how many colors you can write “a” in and so on.
Make your own letter bingo game by writing random letters on a 5x5 grid. Make several different boards so your child can play many times. Make corresponding letters on cut out squares that you use to draw from. You draw a card with a letter and call out the letter name or sound and they cover the letter if it is on their board. Then let them call letters or sounds for you!
Make your own letter puzzles. Using a dark colored marker, write a letter very large on a piece of paper. Cut the paper in a simple way (into 4 squares, into 4 strips, etc). Have your child put the letter puzzle together and tell you the name and sound. They can save the puzzle to play again or glue it to a piece of construction paper. Increase the number of times you cut the puzzle to make it harder. Let your child try making a letter puzzle.
“Alphabet Soup” place some magnet letters or paper letters into a pot. Use a spoon or ladle to scoop out a letter and name it. If you get it right it goes in your bowl. If not it goes back in the pot.

“Alphabet Hunt” can be played any where! Call out a sound or letter name and your child hunts for it. This is great for the commissary. “Bobby I need a vegetable that starts with the /g/ sound” and let him bring you a can of green beans! Make it hard by leaving out the vegetable clue. This is wonderful to play with more than one child- make it a competition!
Make your own tongue twister using a certain letter. Aunt Annie ate an alligator! Busy bees buy bread! Silliest one wins!
Keep a running list of words that start with a letter. You could write the letter in dark marker at the top of a page on a notepad. As your child thinks of or finds words that start with the letter help them write it on the letter page. Start out by having them write the first letter and you finish the word (while sounding it out slowly for them to hear) but then, as they improve, have them start writing all the letters they hear and know.
Turn those lists into a letter book! Fold a piece of paper in half (“hamburger style”) and write one word from the list on each page and let your child illustrate it.
