I used this for two of my kids and we are selling it. I had the grade 2 and K sets so I only used the posters and teacher book for the grade 2 set. I am now selling the K set, and it is basically brand new. The posters, stickers and CD are all still in the plastic wrap. The teacher book was never used (I used my other one), and the picture books were always kept with the kit, so we read them and then put them back. It all looks perfect. Here is our ebay listing Check it out if you are wanting to improve your Kindergarten/grade 1 child's writing or ability to represent their thoughts through pictures. This curriculum recognizes that pre-writing (using pictures and symbols) is just as important as writing. I would totally use this curriculum in K or gr 1 to encourage the transition to written work. Thanks for looking!
