There are unlimited things that you can do on an everyday basis to help your 4 year old. Just using everyday life experiences in the home and in the community as learning opportunities can make learning fun for both you and your child.
Talking about the different things you see as you go places can help your child develop their language skills. You can use activities such as the grocery store, cleaning the house, or even just driving as opportunities to work on concepts such as counting, colors, numbers, and letters. Playing guessing games or I Spy helps your child in a variety of areas such as descriptions, categories, problem solving, among many other life skills.
Taking turns making up silly stories or funny words that rhyme increases your child's ability to use language.
Using these ordinary, everyday activities as opportunities for learning can make the learning and the activities fun!
At this stage, learning to read for your child should involve being exposed to reading in a fun and low-pressure way.
