I am the district math specialist K-12 for Clarksville Public Schools, in Clarksville, Arkansas. I came across the Target Vocabulary Pictures at a Regional NCTM Conference. I ordered a set and then decided they were so valuable that in the past three years, I have ordered sets for all of our teachers from grades 2-6, our junior high math teachers, our senior high math teachers, and all of our elementary teachers! One of our teachers told me the kids look to the wall with the words, and when they are taken down for testing she noticed that the kids still look over where the cards were hanging. That visual memory has helped all of our students! Thanks so much!
