I purchased these posters for use by my granddaughter who is a kindergarten teacher in a public educational facility. The lack of training aids to assist in her teaching efforts have been woefully inadequate provided by the school. She is ecstatic about these training aids, her coworkers that teach kindergarten also vocalized these posters to be extremely valuable in helping them achieve the goal and they indicated a desire and are determined to procure them also. And extremely helpful way for anyone that does homeschooling or just help their children learn. Highly recommend.
