912Geometry_SRT_SimilarTriangles_ExitSlip_Construct_SimilarityExitSlip

This exit slip is for geometry students learning similarity. Two similar triangles are given and students must find the missing side lengths and scale factor. The final question uses argumentation language and asks students to construct an argument justifying the process of how one the side lengths was found.

912Geometry_SRT_SimilarTriangles_Warmup_Construct_SimilarityandDilationsWarmup

Similarity and Dilations Warmup is geared towards geometry students. The task provides two triangles on a coordinate plane and asks students to determine if the triangles are similar and construct an argument that supports the answer. The task does not provide measurements of the sides of the triangle and requires students to be able to read the coordinate plane as well as identify similar triangles.

912Geometry_SRT_PythagoreanTheorem_Warmup_Construct_PythagoreanTheoremWarmup

This warm up is designed for geometry students learning the Pythagorean Theorem. The first two problems contain a triangle with a missing side length that students need to solve for. The third question asks students to use argumentation language to construct a justification for one of their answers. An answer key is provided, with key pieces of information that should be included in the argument.

912Geometry_ParallelLines_ExitSlip_ConstructCritique_ExitSlip–ParallelLinesandTransversals

This exit slip is designed for geometry students working on finding missing angles. Students are provided with a set of parallel lines and a transversal and a couple of angle measures. With the given information, students must find measures of missing angles using knowledge of parallel lines and transversals and the postulates and theorems that come with them. Students are also asked to critique student work and provide a reason as to why a proof does not receive full credit. The proof addresses the common error students make in not identifying that lines are parallel before using definitions such as alternate interior angles.

912Geometry_Midpoint_LessonPlan_Construct_Talk-Frame–Midpoint

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.

912Geometry_GMD_Volume_Worksheet_ConstructCritique_FiringonallCylinders

Firing on all Cylinders is a task designed for geometry students to find the volume of a cylinder in cubic inches. Students are given a word problem, where they know the radius and height of a can, and is shown work determining the volume. With the use of argumentation language, students are asked to use a sentence starter to critique the work, create a claim, provide evidence and warrants.

912Geometry_SRT_PythagoreanTheorem_Worksheet_ConstructCritique_TotallyRadical!

This task is geared towards geometry students with knowledge of the pythagorean theorem and an understanding of simplifying radicals. Students are asked to critique student interpretations of a problem. Ultimately, the task assesses the student’s ability to simplify radicals and recognize equivalence between different radical expressions. Students are asked to construct an argument by stating a claim and providing supporting evidence.

912Geometry_SurfaceArea_Worksheet_ConstructCritique_IceCreamEngineers

In Ice Cream Engineers, geometry students are given the dimensions of a cone and must critique a solution for finding the surface area of the closed cone. Students are asked, through argumentative language and questions, to construct an argument using evidence to support their claim on the solution. Ice Cream Engineers applies knowledge of calculating surface area, using Pythagorean theorem to find a missing side length, and critiquing another student’s claim.

912Geometry_SurfaceArea_Worksheet_ConstructCritique_TheWorld’sMostBoringSculpture

The World’s Most Boring Sculpture is a worksheet used in geometry classes. Students must critique calculations made by someone about the surface area of a rectangular prism. The calculations address a common error in which students only find the area of each different face, and fail to acknowledge how many faces are on the figure. Students are asked to create an argument by stating a claim and providing supporting evidence.
