Posted on by

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.

A template of the talk frame was used to plan a geometry lesson on supplementary angles. The teacher recorded a paraphrased version of the question in the Think section, what ideas would be contributed in the Talk Ideas section, and the realization that linear pairs are formed at the intersection of two lines. Students are asked to name pairs of supplementary angles and construct an argument to convince another person that the claim in true.
