The underlined cards are word problems. The answer key has the core reference for each question. Most are on p16 & 17, the Standard 4 concepts, with some from p12 & 13, the process skills associated with Standard 4. Significant figures are used throughout the answer key, with a few exceptions. There are 22 cards at the end for extra Reference Table practice. I hope they do help your students with reinforcement and review for the Regents Physics course. Have phun!
