I have written about this before, but I can’t overstate the usefulness of this as a hands off helper.
Hung at four-year old eye level, I use this 100 yen whiteboard to review the most recent points covered in the Jolly Phonics syllabus. I have been using this or it’s like for some time. It took a little time to get my daughter used to it, but once she did she enjoyed finding a new word or sentence written on the board and she will try by herself to read it. Once she has read it she will go and do something else. It takes me almost no time to choose the target language and I can change it every morning before she wakes up. I keep it pinned to the shelf next to the dining table where I know she will see it.
