Or with spaghetti. Thats funny to make letters outta wiggly slimy food 😂

With sensory. I put shaving cream on the table or flour and my son made letters in it. I also got bath crayons and he wrote words on the bathtub walls

Find books on things he is interested in .

Turn reading into a song

Make noises while reading .

Writing mhm maybe have him trace. Some fun words.

Or write words that u can draw a picture from the lettets

Forgive my typos please.

Read to him every chance you possibly can and point to the words. Make it fun but studious at the same time. Ask him to read to you. Let him pick from a stack of books that you ah e already approved and that he is interested in. Live in the library with him. Lol. The more he read the more the words will commit to memory. Teach him fun ways of using the letters to make new words from words he already knows. Have him do fill in the blank stories. So much you can do!!!
