Izzy 3:6 Movable Alphabet

Izzy has had an explosion into letters and numbers, she notices them everywhere we go, she is constantly asking what is the name of the letters and numbers she sees.
We are using the phonic alphabet and have started 2 period lessons with the Sandpaper Letters. We have used the sandtray to reinforce the letters and she has freely started to write the letters on her drawings, especially het name.
She saw her sister using the Movable Alphabet and asked to use it, I have let her and am just following her at the moment, letting her touch the letters and telling her the sound if she asks. She also wrote some if the letters on her paper.
