Let’s Try Textbooks

Hi

Been working at elementary school since April after a stint at high school. Getting accustomed to their textbooks. Could someone explain how this activity is supposed to be conducted? It's unit 6 for 3rd graders on page 25. It has "Activity" at the top. I think you've got to give each students a set of alphabet cards. One asks for two letters and the other gives. Then rotate roles. They paste the cards in the top box. The part I am confused is the two boxes below. Appreciate any advice.
