A template of the talk frame was used to plan a geometry lesson on finding the midpoint of a segment. The teacher recorded a paraphrased version of the question in the Think section, anticipated ideas to be contributed in the Talk Ideas section, which include using a ruler, folding paper, and solving algebraically to find a midpoint, and the pieces of information to be learned in the We Understand section. Students are asked to construct an argument on finding the midpoint of a line segment and use argumentation language to convince another person.
