This warm up is created for geometry students learning about triangles. There are three problems, one asking students to find the midpoint of a segment on a coordinate plane, another asking students to construct an argument to justify a claim, and another asking students to classify triangles. Argumentation language is used in the first two problems, encouraging the use of evidence.
