Does anyone have any experience using Scholastic Big Day for PreK Curriculum? My director wants to change our curriculum and this is what she wants us to use in September. I got a sample today and I really like it, except that it does not address high frequency words like my old curriculum does. But before I go gushing to her that I do really like the curriculum that she has selected, I'd like to know if there are any pitfalls I should look out for. Any comments would be much appreciated!
