This performance task on parts of a triangle was given to geometry students. This 15 question multiple-choice and short answer assessment queries students on their knowledge of measurements of internal angles, definitions and classifications, scale factors, finding missing side lengths and angle amounts, and ending in a three part question involving medians. Students are to construct answers and solutions to the variety of material presented.

This task was used as a performance task during our congruent triangles unit. The overall objective was for students to be able prove congruent triangles and classify triangles. This task was given towards the end of our congruent triangles unit either before or after the unit assessment. Students seemed to understand what the task was asking them to do, and the majority of students were able to answer the questions appropriately. Students did struggle on part f where they had to explain the classification of the triangle described.

This task is designed as an assessment for algebra students studying functions. Students are given a table, mapping, graph, and set of ordered pairs. Students must recognize which representation does not show a function and provide a justification as to why each is either a function or not a function. The task addresses common misunderstandings in which students believe no y-value can be repeated and no x-value can go to the same value for the y-value. Space is provided for student justifications.

This is a tool for teachers to use when providing feedback to students about mathematical argumentation. This is used when students need to revise and refine math arguments. It provides specific scaffolds for students. I feel this is a helpful tool because it helps target feedback and gives students a way to revise their arguments.
