My sons M. teacher taught this pre-reading game they do in class - letter sounds and words... (He is 3.5)
The game is similar to eye spy and you can start simply and make it more challenging as she gets the hang of it:
Get an object in your hand; pen, ball, paper, green pepper, carrot [if you play the game while you are cooking, veggies are handy...]
For example you are holding a ball
I spy something in my hand that starts with buh (b) - do not say the letter b, say the sound of the letter b - buh buh.
And your child should guess it and they learn to connect the sound of the letter with objects.
To advance the game, hold an object in each hand (presumably two objects that start with different letters
) so they actually have to guess which object starts with the letter you are sounding.
You can play this game very casually, anytime, while you cook (use food items), while you are walking to the park (pick up nature items on the way ... stick and grass)
Eventually this ties / helps with reading.
