Every once in a blue moon I visit 1st and 2nd grade elementary school classes or kindergarten classes and I like to end the lesson with a big book. But I don't have any big books these days.
I used irasutoya and powerpoint to make a couple of story books based on other stories to use instead.
I no longer visit such classes but I thought somebody else might find them useful.
Little Red is more advanced and maybe a little too scary for very young classes.
