Book excerpt: Ms. Snowden introduces the THiNK Test to Tyaja’s class. Mrs. Snowden tells the kids that T = True, H = Helpful, N = Necessary, and K = Kind. If what you’re about to say isn’t any of these things, she tells them, you shouldn’t say it. Later that day, when Tyaja is about to criticize her friend Dhavi’s new haircut, she is stopped by four little elves sporting the letters T, H, N, and K, who reinforce Ms. Snowden’s lesson and remind Tyaja how friends should treat friends. Tyaja learns that she is the “I” in THiNK!
