When you’re out walking or driving with your child, why not use that time for a little phonemic fun? Pick a “Starting Sound of the Day.” For preschoolers and kindergartners, this can be a single letter, like the letter b. For first and second graders, this can be a consonant blend, like the letters ch.
Remind your child of the sound the letter or letters make, and give some sample words that begin with that letter. Then search for things that begin with that letter.
I did this with my daughter walking home from preschool the other day after she spent the day learning the letter l. She told me all about lions and love and lettuce. As we walked, we found lots of good l words: leaves, light, lines (on the sidewalk), library, and litter (did I mention that we live in New York City?) To help her find some of these things on her own I would give hints like, “Eww! What’s that on the ground that starts with the letter l?”
