I keep a basket handy in our living room (great room? With a high ceiling and wall to wall windows, I never know what to call it) complete with pre-reading supplies. There are Bob books, a moveable alphabet box, some writing tools and sandpaper letters along with a book or two that Bear can confidently
A typical activity begins with us reading a "Bob book" and then focusing on a word from it, in this case "cat". We play around with it's sounds and I help him pick the letters that represent these sounds out of the moveable alphabet box.
If we're feeling jumpy, we go on to match up and trace these letters with the sandpaper letters. Sometimes, we develop rhyming words and I show him how to just replace the beginning sound.
Bear also use these letters to help guide him as he practices writing new words.
There is so very much that can be done with these materials! I'm still discovering new uses for them that help to keep Bear interested and engaged in his learning.
If you're curious for more, just Google "moveable alphabet" and have at it!
