Since yesterday was the first Group Test of the year, I make sure to explain how I graded all of the tests and give time for students to learn from their mistakes. I give students the opportunity to re-explain to each other after they have seen my feedback and to ask questions if they are still confused.
I grade tests by identifying the foundational, application, and extension items on the Introducing Geometry Unit Assessment. Typically, I ensure that the foundational items on the test are worth 70% of all the points earned; this way, a student with a foundational understanding of the unit's objectives can earn a passing grade on the test. From this point, application and extension items, both weighing in at 15%, boost students grades into the B or A range.
Problems 9, 10, and 11 are examples of Foundations items since students have to recall basic information like the definition of "non-collinear" or use appropriate symbols to mark a diagram.
Problem 12 is an example of an Application problem since students apply their understanding of the terms "concave" and "polygon," and then explain their thinking.
Problem 7 is an example of an Extension problem since students identify what they know from the symbols given in the picture to draw a conclusion about how to classify the given quadrilateral.
